Just shot some footage on my Canon T2i this AM at the park down the road here in Tucson and I uploaded what I did here:
At this writing, it's still in queue to be processed so it could be about 45 min or so before it's actually ready. Notice the 2 clip partials - one is shot with the ProLost picture style built from the one described on Stu's site for the 5D I think. The other uses the default Landscape picture style. As you can also see, I have "corrected versions" of both. The Landscape was probably pretty good on its own, but the corrected ProLost looks closer to what I actually shot.
Now, notice in the water in the shadow areas - you'll see colorful flashes. It's far more pronounced in the Landscape version than the ProLost. There are obvious focus issues in the ProLost footage, too.
Are the colorful flashes just my machine, a problem with the DSLR sensor (moving horizontal lines), an issue with strong backlighting AND the DSLR sensor, or is it just me? Can this be corrected in-camera with a better picture style? Finally, for those that use picture styles, what do you use?
Like you said, the Landscape picture style (in this case) was probably all you needed. That looked phenomenal without color correction...great shot! I wish we had nicer landscapes like that up here in Columbus.
I see what you're talking about, and I think it may just be the generic line issue the Canon DSLRs have altogether combined with the detail of the rippling of the water. I must say, because I was looking for it, I found it more distracting in the color corrected version of Stu's picture style settings. The un-color corrected versions look fine, it's just when that detail is enhanced when it comes out.
That is why people need to think through their workflow. There are times and reasons to get it done in camera. But if you are shooting more of a movie or documentary where you need to cut together clips that are taken at different times and different places, you need more correction latitude, for that you need to shoot flat.
So one is right for a given situation but wrong for another.
So if you plan on doing a full color corrections you should be shooting flat.
If you need to process clips quickly and you are have a single setup then it might make more sense to shoot with a finish pic style.
