Hi all, I recently got a rejection for "too much JPEG compression" and it has me puzzled. I am shooting in "Jpeg Large Fine" with my 30D and when I start working on a photo, I have been using the "Save for web" and "Jpeg maximum" in PS7. I have never had a problem with this before and was wondering if anyone can tell me if there is a better way or if I have been doing it wrong all along.

I don't actually see much of a compression issue personally, more of a softness issue. Did you use neatimage or try to do selective sharpening on the aircraft? It looks like the edge around the aircraft is a bit blurred in comparison to everything else. Also there's quite a lot of noise around the underside of the engines and the wingbox area.
Quoting Viv (Reply 2): "Save for web" is your problem.
Save in Photoshop using the largest file size (12).
Seems he doesn't have Photoshop. (It's not cheap! )

I am guilty of selective sharpening but did not use neatimage. How would I save in photoshop?

viv, once I "save as", do my work on the photo, just as an easier way to send it to anet, I usually send it to my "desktop" from photoshop. Am I compressing it again by sending it to desktop? Is that hurting the quality???

You know IL76, I was thinking the same thing because I have never had a problem with compression before. You may have even screened some of my shots in the past. Do you have any suggestions on sharpening that might work better for me?

Anthony,
The example you posted has some weird things going on regarding shapening (no pun intended). Is it possible for you to post a full sized part (like the cockpit section) of the original shot? (our profiles now allow pictures to be uploaded). I can have a go for you...

Have to agree, it's a tough one... Those little titles on the engine are hard to get sharp, if not impossible (at 1000x).
What I did:
- Crop
- Levels (a bit brighter)
- Shadow-Highlight on the shadows (+10, radius 0)
- Resize
- Duplicate layer
- Select the sky with the magic wand at treshold 15 and invert the selection.
- Expand the selection with 1 pixel, then 1 pass of USM 200, 0.2, 0
- Again expand the selection with 1 pixel, then 1 pass of USM 200, 0.2, 0
- rub out jaggies with the eraser.
- flatten image and save.
Ok, it was a rushjob, but you can see the difference best on the "Luis F. Kahl", the registation, the "Embraer 190" and the tail.
I hope it makes sense. Perhaps someone else can do a better job.

Ed, I have to say that is a major improvement! I always have a hard time with Jetblue. I will try exactly what you did and try to get it right but I must say a big THANK YOU for your time on explaining this and for the example. I think one of my mistakes is that I resize it first and then work on it. I also do not really get the duplicate layering thing but all in all I did learn a lot today from you. Thanks again and if you see this shot come your way while screening, have mercy !!! (lol) Thanks again, Anthony

No, I don't think so. But I save in a sub-folder of "My Photos".

Quoting AIRBUSRIDER (Reply 16): OK, I tried as best I could to follow Ed's guidlines..........is this an improvement?
It seems slightly un-centered on the horizontal to me. If you are going to crop tight with the stablizer on the arse end (which I do) then you should duplicate that spacing on the nose.

Yup, I see those damn jaggies.........can someone tell me how to rub out jaggies using the eraser? IL76 (Ed) mentioned how to do it but I can not figure it out. Also, I noticed the crop error Phil, I will probably re-do the whole shot (or scrap it I am so tired of looking at it) it was just sort of a practice using some of the techniques I am learning from this thread. I am using PS7....

Thanks Phil, I will work with that. I am imagining it is ok for PS7??
