Hi everyone, I am in the process of editing some shots from the weekend and one is giving me huge problems. I have converted the RAW image to Jpeg with no sharpening at all, when viewed at full size it is fine. As soon as I resize it to 1024 all the cheatlines produce jaggies, this is before any other sharpening is applied. I have tried it in Jpeg & Tiff but it is the same.
Any ideas ? Please.

Quoting LHRsunriser (Reply 4): Ok so on a hot day, zoomed in quite alot I imagine getting departures. Heat haze isn't going ot be a problem?
Yes, heat haze will be a problem. But your original question made it sound like you were experiencing a very common post-processing issue. Jaggies resulting from extreme image down-sampling is pretty common, and occurs mostly in areas of the image where there are fine/thin horizontal lines.

Quoting LHRsunriser (Reply 9): Sorry for being abrupt Scooter. But heat haze can't be written out of the equation.
No worries...and yes, I agree - heat haze can be a problem. But the OP stated that his problem was that jaggies were occuring when he was resizing his images. If it were heat haze, the the visibilty of the "jaggies" (or slight blur/distortion) would decrease upon down-sampling an image. Trust me, I've been shooting for years, and I do know the difference between heat haze and jaggies/imperfections caused by various post-processing techniques. Heat haze suuuucccks though. I don't even like talking about it.
Quoting Mrk25 (Reply 8): To any of you guy's still in this thread, I read earlier about turning the sharpness setting on the camera itself right down to as good as off, have any of you had any experience with this.
Yep, it's best to turn the sharpening OFF on your camera (if possible).

I know the original thread starter was a question about RAW files and jaggies but my question is what happens when one downsizes a JPEG file?? Same result in that one should expect some jaggies?? I've been experiencing jaggies more and more lately, especially on the leading edges of the wing, is this the exact point Scooter makes when he says jaggies appear on fine/thin horizontal lines??

Hi Matt, I haven't had too many probs with leading edges only horizontal lines, more so when an aircraft has multiple horizontal lines. But I am sure leading edges could be affected in the same way.
