    The trouble with RED

    I am posting here rather than a brand specific area as I think this is a more generalised problem.
    In my case - I have found photographing vivid red flowers really hard.
    With my A-200 I found that turning down the saturation a tad and fine tuning the WB in the direction of Blue helped - but only working hard in Photoshop
    straightened it out. Similarly with my older Oly C-740.
    Now I find the self same problem with the Nikon D80 - in fact - out of the box, and in Auto WB it's a maniak for reds!!!
    Still with patience and experimentation I am generally OK with playing with colourspace and White balance - that is until I try to photograph a lovely Red rose in my garden - it just saturates out and goes a bit on the orange side
    First shot was just after the rain - it looked wonderfull - but my photo did it no favours at all.
    A little PP helped - but that red is still not quite right

    ~ I had another bash later and tried different settings - but that red should be deeper and not so washy!!
    Normally I have been able to tame the reds - with practice on the A-200 I nearly had it nailed - but with the D80 on 'Red steroids' I am really struggling
    With WB on Sunlight and +2blue and the saturation down and colourspace 2 Adobe RGB was the nearest - but still quite a long way off>...
    Any suggestions?/ I mean - I am not new to this !!
    - Is the Nikon a duffer, or is it me??

    If you think red is hard to photograph, try purple and purple-blue flowers.
    Anyway, avoid using auto white balance. How is a camera to know what a correct white balance should be, when there is no white in the scene? It can only guess, without having any actual information.

    Another thing, you used sun light WB, but I see no direct sun light. Why is that? Did you post process all sunny feel out of it, or was it in fact in the shade?

    Use either RAW, or the correct white balance (preferably custom white balance that you set using white or grey). If you shoot JPEG, set the colour and saturation as neutral as possible. And meter on something that has an actaul mid tone, the dark rose you are metering on will alwas get the rose overexposed, and therefore it will saturate the red channel (and that is what you are seeing).

    I tried Daylight/sunshine white as I found when I did tests that cloudy consitantly gives much more red, and shade is like a red filter across the whole scene - but daylight seems to look more natural - Auto, as you suggest, is a bit unpredictable.
    I have to admit that the custom White balance (IE colour temps) is a mystery to me and I couldn't guess which one to choose - and the manual WB requires I have a neatral grey or white card about my person. - If I am indoors I can sometimes find a peice of white paper...
    RAW - I don't do RAW. I hjaven't got a way to convert it and I haven't got the time.
    Sorry if I sound negative - but it's because I feel negative. This camera has turned out to be a real challenge, and it's getting me fed up with the whole photography thing

    Chear up Geoff

    Don't get too despondant I'm sure you'll get the hang of it soon. It just sounds like you've got more options to check out now. I still think that yellow rose bud you posted was stunning. Just stick at it.

    Flowers in particular can pose a real problem or challenge to digital cameras. The ultraviolet range for instance can make flowers on the photos appear different from what our eyes register.

    Thing to keep in mind, when you are outside, you only have to meter ONCE in a lighting situation, there is only one "correct" exposure. So, you can meter on a mid tone in the vicinity of that rose for instance, since the rose is a bit too dark, and you are over-exposing the rose... making the red saturated and "flat".
    Same thing about the white balance... it can hardly be a problem to have a small white paper with you (wallet? camera bag? pocket?). And you wil only have to set the WB once for the light conditions (unless the sun decides to peek through the clouds of course).

    When you have both of these set correctly (I'd use the manual mode for the metering on a mid tone, set the aperture you want to use with the appropriate exposure time), you will get the best results.

    I think you would have been happier if you had gone the Canon XTi route, flower colour wise (and settings wise).

    Must say, I have had no issues with colour reproduction using my tamron 90mm on either my 450D or 7D, however the kit lenses I used to use with the 450D were terrible with colour transmission.

    I always liked the way most Canon cams manage reds - although I have seen them
    over saturate it too.
