    Unhappy Exposure problems (camera, not ....)

    I have booked another trip to the Farne Islands, last time hubby and I went we had very new Cannon 350D's his lense 170-500 mine 75-300. A couple of years later we still have trouble with exposures in extreme conditions..white birds, guano covered rocks and bright sunlight ..... we usually shoot in AV mode. This July I would like to have a better idea of setting to use. Our mid range pics were great..puffins on grass spot on! But I love gulls and kittiwakes........
    We are not anywhere near expert with SLR cameras so please not too much jargon,
    Thanks
    Sheila

    Without seeing some of your shots Sheila it is not easy to say where you might be going wrong.

    Shooting in AV mode is correct, but not with the lens "wide open" (maximum aperture) - reducing the aperture (f-number) will give you more depth of field and greater possibility of sharp, in-focus images.

    You should also shoot in RAW format as this will enable you to correct white balance and over-exposure to some extent in post-processing; especially important for white birds against a darker background. Also, always better to slightly under-expose for white birds, or at least use "single spot metering" and meter off the bird rather than the background.

    BIG subject!!

    Hi sheila, go with what colin says, shoot raw- a lot more scope of rescuing images, being a 350d user also, it is awkward as it does not offer spot metering, closest being the partial setting which meters 9% at the centre,
    If you post some images of the ones you are referring to, then we could probably see what went wrong.

    Thanks Gents, A few pointers there. I have read lots but am overwhelmed by the technicalities I take much better to the 'composition' advice. LOL! The instruction manuals with the cameras were hopelessly tiny print and pressuposed SLR expertise but I will look up the spot metering thing, Hubby thinks 350D do have spot metering ..but there again the little icons on metering mode do not convey much so I will dive into the instruction manual on that one. I also read once that every manufacturer has its own icons for metering modes so the mag. did not illustrate any as they were not universal.
    I tend to use a wide appature to get a fast shot also I like shallow depth of field for out of focus backgrounds but I see the point of a wider depth of field to make the subject more likely to be in focus. All the Farne pics are relegated to disc so I will sort some out and post them for your further advice.
    May I say what a great forum this is... I have been very entertained by some of the threads in the bird identification ..and heartened that I could identify some of the mystery birds!

    Washed out altogether or in the white areas... but if you expose for the whites the blacks will be underexposed...

    Shelia a tip i was offered was to use the * button on the back of the camera.

    Aim your lens at either a uniform gray or green area, press the button to lock focus and then quickly recompose on your subject, half press and take the shot.

    Worth a practice before you go.

    Thanks, Mosstrooper, I will try that outside When the weather brightens)..just used your * method on the computer screen with my macro and got a much more even exposure across the bright bits and dark bits. Again I have been prompted to see what the awful user manual says but at least with a bit of experience and background reading it is a little more understandable. There is an awful lot the camera will do that I have never explored!

    A fact of life i'm afraid. Google "sunny f16" and have a play in manual mode. A 350D doesn't have spot metering by the way.

    Hi, Steve I checked out the manual and proved hubby wrong (as often is the case LOL!).Center weighted is nearest to spot metering I suppose if you are focusing on the centre of the view ( which often I don't do I like to have focus point to one side to get a bird's eye sharp... life seems to be a series of compromises..) I tried Mosstrooper's * method last night and instead of a black shillouette of a tree againsed a bright sun setting sky I got detail in the tree ..but the sunspot was then far too bright. I suppose I want unobtainable perfection in extreme lighting conditions.
