    Some Flowers

    Just playing with a really shallow DoF, thought the results were kinda fun, what do you think?

    Hi Tobias. Interesting experiment/concept. I think I would have liked it better if there was a 'definite' focus point. In most of these, the entire image seems soft.

    There seems to be another effect. The purple has lost all detail. I wonder if it's from some post processing, or just from having such a shallow depth of field?

    Tobias, really like the first photograph. It's an interesting flower shot.

    Hi Andrew, I was actually trying to make the image over soft to create a slight dreamy effect. Getting one central focus point was tricky because it was just a pot of really small purple flowers.

    Hi Tobias,

    Of these, I prefer #2, mainly because of the composition.

    Hi Andrew,

    It is likely because the blue channel is blown (over exposed) - check the blue channel histogram and you'll see a line of pixels climbing the right hand side (in 1 and 3 only, 2 looks OK).

    Tobias,

    When shooting really saturated flowers like these, you need to review the RGB histogram in camera at time of shooting (assuming it has one) - the luminance histogram will give grossly misleading results because it judges blue as only about 10% 'important', compared to green being 60% 'important' and red 30% 'important'.

    You can see the effect on blue here:

    Thanks Dave, that's what I expected, but it seems I've been saying that a lot lately. I didn't want to sound like a broken record.

    Tobias, I still like the shots, and they're a great subject too - don't get me wrong, just not how I would have approached it. I think you've achieved what you were looking for. For that, well done!

    Yeah I actually threw the luminance dial off the charts, I think thats what has lead to the softness. I didn't really achieve the affect I was looking for but I still think they look quite interesting.
