I've been pondering and have a question for the PS pros...sorry if this topic's been brought up before, I poked around a little and didn't see anything.

Regarding PS and resizing. I have photos I take and I do manips or adjustments to them in PS...levels, filters, color corrections, yadda, yadda, yadda. Anywho, I also have to resize my photos to 16x12 before I upload to Caedes. My question? I'm getting there...

Should I resize first then do my post work, or, do my post work then resize? Is there a difference? I don't know myself, but would assume so durning compression of said piece.

I don't use PS, only Photo Editor, but I doubt there's much of a difference. I generally like to edit or manip the image at the largest res. and then resize it to a smaller res, as I've noticed it gives better quality, just like in Apophysis.

Well .. what is your original size?

for example, when I work on an image .. I work at 3200x2400 x 300dpi .. I, of course, do all my sharpening, etc at this size then resize down to 16x12 for upload

the "bicubic al gore rhythm" ;o) .. does a bang up job of smoothing out the wrinkles (sometimes too good)

working at 300dpi is very helpful, in my humble opinion, as it gives PS more pixels to work with when resizing

note .. when using stock images I size up to these dimensions (when appropriate) .. for example, the "scenic" base image .. I hesitate to size up more than double, but I'll do it, I'm not proud (I do change dpi to 300 even if I don't change actual dimensions ...

fractals, I render at 32x24

The pic I'm working on now is 2592 x 1944 with 180 horizontal dpi and 180 vertical dpi. I hope that's what you needed to know. I've been doing my post work first then lastly resizing. I don't know if it really makes much of a difference..was just thinking out loud again...

~still waiting for that brew & wondering what's keeping the bar keep~

Yep what Baby Big Ears said... thats how I do mine too.. =)

I do all my work first on the large version, then resize last of all. Not that it really makes any difference in the final analysis - I've done it both ways and can't discern a difference. The nice thing about doing all the work up front is that you have a final product in jumbo size - one that you can print posters of if you want to.

I could be wrong .. but .. levels, color corrections etc won't be affected by resizing .. things, like, noise reduction, sharpening, photo-compositing would probably see the biggest benefit \ detriment

actually, levels and color corrections will be affected if you're sizing up, because sharper lines will appear when you blow it up… the pixels weren't there before to include in the smoothness of the change.

The rule of thumb is… you can always go down or take out… the other way doesn't work so well 8•)
