Guys, I just have rejected one image at IS for purple fringing. This is the problematic part sent from IS. Can someone tell me where the reviewer saw purple fringing?
Parachute is purple, and some cables are purple tho ;D

the pic is too small, but if I AM SUPPOSED to see fringes to agree with the IS reviewer   ;)
 i would say it's on his lap and behind his ankle . as i say, only guessing from this size.

It looks to me like what they saw was purple cables :)

Reminds me of that famous rejection, your blue bin appears purple :D

Oh, a bigger version of the image can be seen by clicking on it.

I checked it in 300%. Those are bit soft edges, probably due to motion blur because the parachutist moved his leg, but there is no trace of fringing. Maybe it's on some other place...

I can see a little fringing around the left foot on the bottom edge also along the edge of the black part of the jacket. Its there but in your defense its pretty minor  :)

Tiny amount of purple fringing around shoes and coat, tiny...

Yes, I see it. Is it really the reason for rejection, or maybe there is some stronger fringing?

Well... aren't the cables supposed to be white? Unless they are actually purple (and the reviewer cannot know that), there is a lot of CA along the two main cables I would say.

Two main cables are purple. Cables on parachutes are almost never white on todays parachutes btw. They are divided into groups (A,B,C etc) colored with different colors by groups. I know that because I am a paragliding pilot.

You know that, but most don't (myself and the reviewer included)... and it looks like CA  :-\

Should I submit this to scout? I never did that before.... Or maybe I should change the color of those two cables... hmm...

Zoom to 700% on this clip, and the edges are purple all around the guy and parachute.  Must be som kind of  edge/contrast sharpening to make it look sharper than it is. Do you have that setting in your camera?  

This may be on all cameras though. Havent thought about it before :-[

I tried and yes I see it too. It is just a scary thought that we are starting to zoom in at 700% to see these things. I would still like to think that the reviewer simply saw purple cables as as white cables having purple fringing :)

sorry to say but I see plenty of CA around black clothes and along the lower shoe. I clearly see it at 100% which means it's too much.

Actually Miklav, if you think about that part of dark clothes behind him, that's purple too. It's part of the parachute. It's where it was before opening :) That's why you can see purple edge around it. Pants are dark blue, almost black. I don't see there any purple fringing, only soft edge :)

But maybe the reviewer also thought it was fringing.

To be honest whether you see and/or believe there is purple fringing or not is negatable, if you submit it again or ask scout it'll probably get rejected for the jpeg artifacting of which there is quite a bit, have you used image degrader noise ninja on it?

If this is it, don't you think this is quite insane?

Nope, no noise reduction at all. Shutter speed was 1/500, and ISO was 100. I have series of images made that day with very high acceptance rate. Actually, this is the only image rejected from this batch... I was just curious. I wrote to scout anyway. I just wanna see what he thinks.

I am sorry to say I see a lot of fringing also. It happens alot when objects or people appear against the blue sky. I have had a bunch of rejections for this.

You also have another issue, haloing. This can be seen along the guys right pants leg, where there is almost a dark line outlining his pant leg. You can also see it along the left edge of the red strap just over the guys shoulder (his left shoulder, right shoulder as you look at the picture. The haloing creates a white gap between the sky and the red strap.

Its a great photo, I think it's salvageable, but would need some work. I wouldn't submit to scout. Can you resubmit? If so, I would fix and resubmit.

I only ever view my photos and correct at 200%. Look at ANY photo at 700% and you're going to see problems. It was my understanding that photos get reviewed at 100%. If you fix them at 200% and they get rejected, I say give up and move on.

I don't mean to be harsh, I'm speaking from experience on these rejection issues!

Thank you cclaper,
I don't think I will bother with resubmission. I have several pretty similar images accepted already, so... :) I'll throw this one...

Yesterday I got a rejection for 'an unacceptable amount of purple fringing' on an image with a field of purple hyacinths! I am laughing about it for 24 hours now!  ;D And indeed looking at 300% or so, I can find a little bit purple that seem not to be original to the flowers. Using software removes all the purple from the image and cleaning up half a million tiny hyacinth flowers by hand... no, I don't think so!
Of course there's nothing wrong with your image. Demanding this level of perfection is deadsting to creativity. Perfect beauty is boring.  And when you might ever reach that level they sell it for 0,30 ct....:D
These rejection reasons seem extreme to me and you need to have a little bit of sense of humour when uploading to Istock!  :) (and not only to Istock...!  ;)

whitechild,
I have a cool photo that I took inside of the Opryland Hotel, looking up at palm trees and the skylight that covers the whole hotel. It has a TON of fringing. I started to fix it all, but about an hour into it and halfway through the photo, I kind of gave up. It is a lot of work for sometimes a small return.

I took a look at your port on istock and you have some great photos. I added some to my lightboxes, I hope it helps you get some sales!
