  1. Firstly - apologies to those who may be fed up of newbie
    questions about digital cameras on here!

    Since I lost my old faithful 35mm camera last week I'm
    considering replacing it with a digital, but to be honest I
    don't really know what I'm looking for - I get the
    megapixels side of it and that's about it. For the 35mm side
    of things it took me long enough to get my head round the
    ISO numbers (with the help of this newsgroup a couple of
    years back ;-)

    My old camera was an Olympus AF10-XB compact model (details
    at <http://makeashorterlink.com/?O2B551088> ), point-and-
    click, nothing fancy, I was happy with the results. I'm
    after something similar. Pics will mainly be kept on my
    computer, some on the internet, if any are printed they
    won't be bigger than A4 size.

    Questions I've come across in my research:

    - Do pictures get more "washed out" in bright light
    than 35mm?
    - What's the lifespan of batteries, assuming I use the
    viewfinder primarily (rather than the LCD screen)?
    - Last week I used up 4 rolls of 36-exposure film across the
    whole week. What's the equivalent memory needed for this
    many photos?
    - Are they more prone to damp and cold than 35mm cameras?

    Many thanks

    Iain

    Oh boy, this is a cracker ;o)

    1) Some cameras are more prone to blow outs than others.
    Comes down to how the sensor handles the light, cheaper
    you go the worst it can become...
    2) Depends on the camera and types of battery, a 10D dSLR
    can pull about 400-500 shots with a 1Gb Microdrive, my
    602 Pro can pull about 400 with the same Microdrive but
    using standard NIMH (2000mHA) batteries. Also down to how
    much you use the LCD preview and flash...
    3) Depends on the size of MegaPixels and the final image and
    resolution you choose, such as my 602 can fit about 440
    shots (6MP fine) on a 1Gb Microdrive but a Canon 10D can
    do about 250 ish RAW iirc.
    4) I have not experienced this, but if you keep a sachet of
    silica gel (you get this with most electronic items) in
    your camera bag then you are helping to keep the
    moisture out.

    How big a camera do you want to carry, how much zoom do
    you need, what size of prints do you want to print. Do
    you want manual or full auto, do you need the ability to
    use a external flash, these are all questions you need to
    ask yourself.

    You note I have not said anything about MegaPixels, it's a
    fallacy that people think that a 5Mp is better than a 3Mp
    camera, it not's necessary so it comes down to how well the
    picture is rendered. Don't fall into this trap. 3Mp will
    produce decent 8x10 shots.

    Steves-digicams.com and DPreview.com are good places to
    start.

    Check out Fuji, Canon and Olympus cameras these have all got
    good reps, Kodak do some good cameras as well.

    I'm happy with my Olympus C5000z camera. Was also happy with

    manual controls and aperture / shutter priority.

    hope this helps.

    The general concensus is that 6MP is roughly equal to the
    resolution of film, however the lenses on cheap compacts are
    hardly of the best quality so probably 3-4MP will do.

    In my opinion 4MP is enough produce a good quality A4, 3MP
    is probably okay at a push. Note that most 3MP digital
    cameras are actually 3.3MP so there's not that much
    difference with a 4MP.

    Quoted message said:

    - Do pictures get more "washed out" in bright light
    than 35mm?

    That's primarily an issue of exposure. In my experience most
    exposure meters tend to overexpose, resulting in washed out
    skies. Best to take the reading off the sky to prevent
    overexposure. The other thing is that digital cameras often
    produce lower contrast images than film. While this is
    actually a good thing, it results in flatter looking images
    with less colour. Boosting colour is easy, so is contrast.
    Boosting contrast also boosts colour. There should be
    settings to adjust in camera to get a good looking result
    straight out of the camera, or (ideally) you can post
    process later for the best restuls.

    - What's the lifespan of batteries, assuming I use the

    Depends on what batteries the camera uses. I've heard that
    camera's which use AAs have a pathetically short life. Li-
    ion batteries are waaaaaaaaaay better! This may vary from
    manufacturer to manufacturer but Canon estimate 450 shots
    with the LCD on, over 1000 with it off. People have reported
    going away for a week and not running out of battery power.
    You're more likely to fill your memory cards before your
    battery runs out with a Li-ion battery.

    With a 6MP pro camera using top quality RAW mode, 1 gig.
    With a 4MP camera in RAW mode, 576 meg. 4MP at top jpeg
    quality, 288 meg.

    Quoted message said:

    - Are they more prone to damp and cold than 35mm cameras?

    Don't know about damp but you definitely don't want to get
    them wet. Not recommended for use in rain, although I know
    someone who's used his Canon G3 in the rain for a short
    while without problems. Cold is really a battery issue, it
    won't last so long. I've used my G3 and 300D in sub-
    zero/snow conditions though without any problems.

    It depends a lot on the type of battery and the
    milliamperage thereof. If you can find 2100s or above the
    battery life will be good; however always carry a couple of
    spare sets if you're going to be away from your car for more
    than a day at a time (see below). Use your camera at its
    maximum resolution. You'll get fewer pictures to your cards,
    but you'll be able to crop and play with them better if
    they're bigger to start off with. Always have at least one
    spare card with you, of whichever memory your new toy uses,
    and don't necessarily go for the biggest cards (in terms of
    Mb) you can get. Oh, and you'll probably want a card reader
    to plug into your computer, so that you don't need to use
    the batteries whilst transferring your photos to the HDD.

    Thinking of batteries, I bought myself a 'new toy' over the
    weekend and I'm very happy with it: one battery charger from
    Maplins. It runs from either the mains or a car battery (via
    the lighter) and can charge NiMhs or Ni-Cds as long as you
    don't mix them. The big things for me are:

    * Works from car battery;
    * It can charge *single* batteries! So if, like me, you have
    the odd 'flattery' that you can't otherwise charge because
    it's on its own - well now you can;
    * As long as all the batteries you're charging have the same
    chemical wotnot, they can have different milliamperages,
    as each is charged separately;
    * It came with 4 x 2300ma NiMhs, which it charged up in just
    over an hour in the car.

    It's a... hang on.... <rummages> Vanson 1-hour NiMh/NiCd
    Battery Charger.

    I don't have shares in the company - I'm just very
    pleased with
    it.

    Possibly. Digital cameras have a smaller dynamic range

    Exposure=20 therefore needs to be more accurate in difficult
    conditions. There are advantages, however - it is easier to

    Again, on my (4MP) G3, the highest quality JPEG was ~2MB, so
    a=20 256MB card would be enough. I tend to shoot in RAW
    mode,=20 however (gives you more options for post-

    card is under =A350 these days. Another factor, though, is
    that you have the ability to review=20 your images after
    shooting, and delete the ones that didn't=20 work. In this
    case, you wouldn't need so much storage.

    I don't believe so.

    My wife and I also made the move from good quality film point-

    the=20 improvement in the quality of our pictures. Having

    Okay, lots of technical answers already. General user
    answer, I have an Olympus MJU 300 as my company camera (also
    personal use) good quality build, metal casing and pictures
    are equivalent to a 35mm and it's 3 meg camera.

    MJU 400 4 meg available for £168 see
    lauriem.plus.combargain basement.html

    Go and have a look at it in the flesh to convince yourself.

    Please look at the Canon specs for their cameras that use
    AAs and you will find them comparable to the specs for their
    battery pack cameras when running on NiMH.

    e.g. the A80

    powershot.comspecs.html

    AA ALKALINE LCD ON Approx. 250 LCD OFF Approx. 800 AA NIMH
    LCD ON Approx. LCD OFF 350 Approx. 1000

    That hardly makes the 450/1000 you quote for your Li-ion
    waaaaaaaaaay better now does it????

    Much of what you post does appear to be based on fact but
    you do seem to repeatedly bark up the wrong tree on this
    particular point.

    I have found that CCD doesn't necessarily respond in exactly
    the same way as film, especially in extreme light
    conditions. It's a case of practising with, which of course
    you can do your hearts content. Delete until your happy with
    the results.

    Quoted message said:

    Firstly, don't bother with digital viewfinders. They are a
    complete of space. A review screen is essential and if
    you're only using it to review what you've taken then it
    wont impac too much on bettery life. Do not go for anything
    that uses a proprietary battery so you can go for standard
    rechargeables, as discussed.

    - Last week I used up 4 rolls of 36-exposure film across

    Depends on the resolution. I have a 128mb card and 64mb card
    for backup and unless I'm doing something that may be used
    later for A3+ work I will shoot at about 3M pixels and I
    will get your 144 shots on my two cards. Also, you'll find
    that you'll edit out your weaker shots, making better use of
    what memory you've got.

    Quoted message said:

    - Are they more prone to damp and cold than 35mm cameras?

    Not that I have noticed but I have recently had to send my
    camera back to Fuji after it broke when dropped only 18
    inches in its case, so in my experience they are more
    fragile than thier predecessors.

    Other factors: Digital zoom is also a waste of space.
    Optical zoom is the king. Check out how many ISO equivelant
    speeds it supports and shutter speed equivelants. Mine will
    do up to 400 ASA and 1000th sec but I could sometimes do
    with some more extremes. Mine also lacks a B mode which
    really irritates me.

    With all technology there is a pay-off between
    sophistication and ease of use. I don't mind paying good
    money for a camera with a lot of features because I know
    that I am going to use them. I am sure that someone can
    recommend an excellent point and shoot variety of camera
    that delivers excellent picture quality with limited
    flexibility.

    Iain, you've had a goodly few responses that have approached
    answers to your tech questions, not my field ;-) but I might
    suggest a different tack in your quest for a new camera.

    First of all, I'd suggest you're more serious about your
    photgraphy than you give yourself credit for, anyone who can
    shoot 4x36 in a week is not hanging back for bets! So I'd
    suggest you look further "upmarket", i.e. consider spending
    more, than you might have done initially.

    Other 'roundabout things to think of;

    - generally the more MP the better

    - more memory on your memory card is better

    - try for a camera that gives you RAW mode

    - user the LCD, especially if your chosen camera shows you
    the histogram, the histogram is a "good thing"

    - brand / make, browse the shelves at your newsagent and
    read their "buyer's Guides", they price-bracket and give
    an overview of each product.

    - you'll need image-processing software too, the stuff that
    comes with cameras is always pretty basic, useful for file
    handling and not much else. Photoshop is the de facto
    program to use but its expensive, alternate sources might
    resolve this problem to greater or lesser extent. Another
    option is The Gimp, gimp.orggimp.org which a lot of
    people rave about... and not just because its free.

    - don't dismiss photo processing on your PC too much because
    the options it opens up to you are immense... and its
    exactly the same as working in a dark room (i.e. accepted
    practice... you don't need to think that what comes out of
    the camera is the finished product, especially since film
    photographers don't)

    - have fun, its great, produce stuff with basic errors and
    notice your mistakes immediately soemone say's, ever so
    gently, "you may want to consider this" :-) Yes, I wear
    that hat at this moment in time :-) and would love to hand
    it on to someone else!! Until then, tho', I'll still be
    plugging away.

    Since I lost my old faithful 35mm camera last week I'm
    considering replacing it with a digital, but to be honest
    I don't really know what I'm looking for - I get the
    megapixels side of it and that's about
    it. For the 35mm side of things it took me long enough to
    get my head round the ISO numbers (with the help of
    this newsgroup a couple of years back ;-)

    My old camera was an Olympus AF10-XB compact model
    (details at <http://makeashorterlink.com/?O2B551088> ),
    point-and-click, nothing fancy, I was happy with the
    results. I'm after something similar. Pics will mainly be
    kept on my computer, some on the internet, if any are
    printed they won't be bigger than A4 size.

    Questions I've come across in my research:

    - Do pictures get more "washed out" in bright light
    than 35mm?
    - What's the lifespan of batteries, assuming I use the
    viewfinder primarily (rather than the LCD screen)?
    - Last week I used up 4 rolls of 36-exposure film across
    the whole week. What's the equivalent memory needed for
    this many photos?
    - Are they more prone to damp and cold than 35mm cameras?

    Earlier this year I opted for an Olympus mju-digital 400. My
    reasons were that I have used other olympus cameras, both
    SLRs and compacts, and they all have had good lenses and
    exposure metering. Also the mju series of cameras are small,
    easy to use, and are water and dirt resistant.

    I use my cameras to record my outdoor activities in
    rockclimbing, mountaineering and ski-mountaineering. They
    have to put up with conditions such as sea spray, rain and
    snow, cold and heat, and be usable in all seasons. Weight is
    also an issue for activities such as multi-day
    mountaineering and ski-mountaineering.

    I use the maximum image resolution on the 4Mp camera but
    compress the files onto the xD picture card as jpeg files.
    This means that a single 64Mb card can hold about 150 shots.
    The lithium ion battery seems to last very well and on a
    recent two week ski-tour and taking about 100 shots each
    week, the battery was only charged once in the middle
    weekend, and even then it wasn't empty. The automatic
    metering coped well with the snow conditions, it also has
    the ability to set exposure compensation, but I found this
    was only necessary for early morning or evening shots.

    I'm pleased with the results so far and find that it is a
    reasonable digital alternative to my mju 35mm compacts
    (which I still use).

    (2000mAH NiMH) if they have not been charged for quite
    some time.

    It also used to be nice that the spare camera batteries
    would fit my headtorch and GPS but now I use a Tikka and
    Geko 201 most of the time I no longer have that advantage.

    I've not had any experience of such cameras myself, I was
    simply going by what I'd heard from other people. I'm sure
    I've been told that AA battery life is terrible in digital
    cameras, often running out after just 20 shots or so. Maybe
    they were low capacity rechargeables, I don't know.


    The first digital camera I used (an early Olympus Camedia
    loaned by a client for work) would only do very small number
    of pictures on fresh alkaline AAs. But it would quite
    happily take pictures all day on 650mAH NiCds!

    The alkaline cells just couldn't deliver the high current
    used by the camera but the NiCds had no problem with it. I
    was gobsmacked at the difference especially as the nominal
    capacity of the NiCds was 1/4 that of the alkaline cells.

    From Canon's figures quoted above it seems that the current
    drain of modern cameras is not as bad as with the early
    models so alkaline cells are not a complete waste of time.

  13. Phew! Thanks everyone so far for your help, after re-reading
    my own post I was expecting more along the lines of "get in
    the right newsgroup"!

    I must admit most of the technical stuff went over my head,
    but then I've just back back from work so I'll try reading
    it again later. My old camera was auto-focus, and that's
    about all I knew about it - no manual controls for
    exposure/shutter speed/whatever.

    In terms of how serious I am about photography, I spend a
    bit of time framing the shot and do the odd experiments like
    taking a picture into the sun (some nice silhouttes as a
    result), and I've picked and chosen who to develop them for
    me. I've only gone into the technical side of it once, and
    that was asking what ISO film to use.

    Saying all that though I'm reknowned for under-selling
    myself ;-) but money's the big issue really, whatever I get
    it'll be going onto the credit card to pay off slowly.
    What's tempting me most is no cost of films & developing
    (getting towards £10 a go, to buy the film then get it
    processed).

    For now, the Olympus MJU 300 or 400 are looking tempting.
    Any more advice is welcome.

    Cheers Iain

    Take a look at the Canon A80 and A75 as well. The weather
    resistance of the Mjus are a plus but Canon has a very good
    reputation for image quality.

    Take a look on www.jessops.com to see the specs.

    If you have a branch of Jessops near you pop in and have a
    play with the models you are interested in.

    You are perfectly correct Paul. The difference is not in the
    capacity but in the chemistry.

    For instance a AA alkaline has about 2400mAh capacity but
    only lasts a few shots or a few minutes, whereas a NiMH AA
    of 1200mAh capacity works for a much longer time.

    Basically alkalines are not manufactured to mix the
    chemicals fast enough. They can supply the 1A current for a
    few minutes and then the chemicals around the 2 anodes are
    exhausted and the batteries are not physically able to mix
    the depleted and fresh chemicals fast enough to keep it
    going. That's why when you give it a few minutes rest it
    will give you a few minutes more work. And also why your
    "exhausted" AA from your camera will drive a torch (low
    current) for nearly as long as a new one.

    Size for size, yes. But I am frustrated by the small Lion
    batteries (550mAh) in my Minolta tiny camera which runs out
    much faster than my Canon 4xAA.

    - What's the lifespan of batteries, assuming I use the
    viewfinder primarily (rather than the LCD screen)?


    It depends a lot on the type of battery and the
    milliamperage thereof. If you can find 2100s or above the
    battery life will be good; however always carry a couple of
    spare sets if you're going to be away from your car for
    more than a day at a time (see below). Use your camera at
    its maximum resolution. You'll get fewer pictures to your
    cards, but you'll be able to crop and play with them better
    if they're bigger to start off with. Always have at least
    one spare card with you, of whichever memory your new toy
    uses, and don't necessarily go for the biggest cards (in
    terms of Mb) you can get. Oh, and you'll probably want a
    card reader to plug into your computer, so that you don't
    need to use the batteries whilst transferring your photos
    to the HDD. tinyurl.com9bg2

    Thinking of batteries, I bought myself a 'new toy' over the
    weekend and I'm very happy with it: one battery charger
    from Maplins. It runs from either the mains or a car
    battery (via the lighter) and can charge NiMhs or Ni-Cds as
    long as you don't mix them. The big things for me are:

    * Works from car battery;
    * It can charge *single* batteries! So if, like me, you
    have the odd 'flattery' that you can't otherwise charge
    because it's on its own - well now you can;
    * As long as all the batteries you're charging have the
    same chemical wotnot, they can have different
    milliamperages, as each is charged separately;
    * It came with 4 x 2300ma NiMhs, which it charged up in
    just over an hour in the car.

    It's a... hang on.... <rummages> Vanson 1-hour
    NiMh/NiCd Battery

    After a while my Vanson from Maplin never stopped charging
    on one cell position. I could charge 3 batteries reliably
    but that was not much use...

    Cost me £40 too.

    First of all, I'd suggest you're more serious about your
    photgraphy than you give yourself credit for, anyone who
    can shoot 4x36 in a week is not hanging back for bets!

    Ha! I take that many in a day! Half a roll a day is really
    restrained
    IMO. :-)

    Ah, but you've got that itchy finger thing that makes you
    hit the shutter release shutter release shutter release,
    plus I'm sure spaceitis will get you, even
    subconsciously? ;-)

    I'd take praps a roll-equivalent in a trip oot (Weds eve)
    but I'd tail off in my enthusiasm over a week ;-)

    One reason I changed to digital was that I took typically
    700 photos in a week of holiday in good weather on my film
    camera. I recovered the cost of the digital mighty quickly
    in not developing film, especially as I had them all scanned
    to CD at the same time.

    My advice is to buy cheap. Regard the £100(?) you spent as
    learning money to decide what you really want. You can
    always sell it on eBay afterwards anyway.

    I went for a Canon A20 as my learning camera. I moved up to
    Olympus E10 SLR. But the A20 takes most photos for me as I
    take it on all my walks as a visual record.

    Seconded.

    Always worth downloading full pictures from

    www.imaging-resource.com

    so that you can print the same picture taken on
    different cameras.

    Not so long ago I saw amazon selling Canon A60's for £100,
    which is a very good deal, though I'm not sure if you can
    still get them.

    You can, but beware when they're from abroad. You pay VAT
    and import duties amounting to perhaps 20% extra.
