Help With Quality Issues

Mon Oct 17, 2005 3:51 am

These rejections were all for quality. I took them with a 300D and a 70-200 f/4 L lens. I assume I am messing up the post processing, but I really don't know. If anyone wants to see the originals I can email them to you. Thanks.

I seem to recognize all of those shots.  Big grin

They look pretty darn good to me, but what I think has nothing to do with A.net's formula.

Hi Matt,

Not sure if I can diagnose correctly, but I do see a few issues. The LAN is badly compressed as far as I can see, making it soft and blurry.
The other 3 all have some haze or jaggies, look at the tails for example. I am unsure whether this can be corrected by sharpening (USM), or whether it is a heat effect. From the looks of it, it was a warm day with much turbulence right?
How do you sharpen images? Unsharp Mask in progressive steps?

Other than that, great images indeed!

It was nice and cool with only a light breeze IIRC. Then again, maybe it was different on the tarmac. I have several of the same shots on my computer and they look similar to WT's (350D).

Interesting remark about compression. I have never had issues with that before. It might just be heat haze, but I am unsure. I always sharpen in 1 step with USM at 0.3 radius, 0 threshhold, and depending on the photo between 50-150%. I apply USM only to the aircraft and objects, but not the sky. The originals look a lot better than the final image. Here is the original LAN shot.

Matt, I had another look at the LAN shot you just posted, and the full-size version. In my view that full-size version needs more sharpening (I'm using the approach of several passes of 50%). What I always do is resize them to 1024 or similar size first, and then apply USM sharpening. That might help?

In any case, the original one above and the one on imageshack (not the full version) have jaggies. Since the full-size one doesn't have it, I thought it was due to the compression of the size (so I didn't mean jpeg-compression).

?? Then why process them? I'd say your exposures are whacked. The sky is a different color in each one. That should tell you something all by itself.

That's a little harsh, but it still had me LOL.

Yeah, it should tell you to upload only one photo at a time.  Big grin

Wow, I am so cunfused at the moment. First, Edoca, I always use the same workflow, which I think I got from Fergul of Ireland. It is very simple, and has worked for 125 shots of mine. Second, Jeff, what are you getting at, I am not clear on your remark. If the originals looks ok, than the final should look ok too. The originals look good because they are huge, when resized the quality does not stay the same on my monitor. It might be because I am on such a high resolution monitor. As far as the exposures, it was partly cloudy with some haze, so the lighting changed, plus these shots were taken over about 4 hours. The sky color is not going to be the same as well as the exposure. Please clarify what you are saying.

I notice that the sky changes colour when i point the lens in different directions a few degrees up from this horizon is enough to change the colour sometimes .
