I have a photo in the screening queue that is expected to undergo screening today or tomorrow. I have just taken a look at it and noticed has imperfections, JPEG artifacts that were not present before its upload to the screening queue. I can confirm that the artifacts were not in the finalized image that I submitted, which is still saved to my computer.

The photo was 684KB and thus I believe should not have been compressed in any way, as it was not over 1MB in size. I am now worried that the photo could be rejected solely because of this.

This is the photo in question (I am linking to it because the image function is still broken):
http://www.airliners.net/addphotos/b...1246146936.9345n874ga_attempt1.jpg

What should I do and what can be done? Should I delete it from the queue and reupload it? Would this issue reoccur if I were to do so?

Thanks in advance.

It was rejected last night for soft.

My question now is: is this a result of the JPEG compression or is there an area of softness in the image that I am oblivious too?

(This can be moved to aviation photography if seen fit.)

If its soft ,it's the forward part of the plane thats soft.

Love the angle and the clouds, but that high mid-day sun is a killer. It looks like you have great access, try it before 10am or after 4pm  thumbsup

Quoting Plainplane (Thread starter):

All web galleries during upload compressing a little bit an uploaded material. They have a scripts that cut out an exif and compressing pictures. They have to do that because of saving space (about 1/4 of picture weight). We have to remember that. I am checking my uploaded pictures after upload and if I see some artefacts I am trying to improve photo.

I don't think I'll have a chance for repeat access any time soon. It was a special favor.
