View Full Version : "JPG from picture style" equivalence to "RAW + post processing steps A,B,C"?

I am relatively new to post-processing raw files. Presumably Canon put some thought into coming up with the various picture styles they pre-defined in the camera (40D in my case).

Has anyone put together rough equivalences of "a JPG out of the camera with picture style X" is roughly equivalent "a RAW file with post-processing steps A, B and C"?

For example, a JPG generated in the "Landscape" picture style (for vivid blues and greens, and very sharp images) would be roughly equivalent to taking the RAW file and applying the following adjustments:
A) unsharpen mask at 30%, 0.5, etc..
B) adjusting saturation ...
C) etc....

I think I would find these "cookbook" steps a useful starting or jumping off point for enhancing my post processing work. In my particular case I'm using CS3, but I suspect this would not be too particular to the exact PP software in use.

Thanks... Steve

DPP lets u do just that, but i find lightroom better, make your own styles.

Actually, you don't need to replicate the picture styles.

I'm not certain you could, anyway. If you download the Picture Style Editor, you'll see that the picture styles are actually able to target individual color ranges with color look-up tables, etc. They can be pretty complicated.

Luckily, DPP allows you to select any picture style you'd like after the fact if you shoot RAW. The one you had set in the camera is just the one it will display by default when you pull the picture up for editing.

Also, Canon published several new picture styles as well. They're "Emerald", "Twilight", "Studio Portrait", "Snapshot Portrait", and "Nostalgia." You can find them on the Web site.

I guess I wasn't very clear in what I was asking - or maybe why. I'm not so much looking for how to get a given picture style out of a raw file. Rather, I was thinking along the lines of...

1) I'm just learning post processing.
2) Mimicking the "post processing" that occurs "in-camera" when creating a jpg with a picture-style setting would be a good starting point.
3) So I wonder what steps in CS3 I would have to do to a raw file in order to accomplishing the same (or close) post-processing that occurs for a given picture-style.
4) Now that I see what's happening to simulate a "landscape" style, I can start diverging from those steps and seeing the effects. Same with "portrait" and "emerald" and other styles.

Does what I'm asking make sense? Does it sound like a reasonable way to get more detailed into post-processing in CS3? I'm looking at this more as a learning method than just trying to get something done.

I guess the short summary is that I would like to be able to manually adjust a raw file to generate a JPG file roughly the same that a "picture style" would do if generating a JPG directly.

Actually everybody knows how to do that but if we told you, you wouldn't learn.:evil:
Seriously, analyze what the P.S. does and then play around trying different things. If you are working on the RAW, you can't hurt it and if you are editing a jpg, hey, it's only a jpg. Delete your screwups.
