Rejection question

[dlowwa]

Good evening,

I picked up a couple rejections lately, both for Colour.

Come to think of it the rejection before that (expired) was also for the same reason:

I'm aware of at least 15 (fifteen) different image problems that could be covered by the Bad Colour rejection. None of the above images came with screener comments so I'm hoping someone from the crew can comment on what the specific issues may be.

Thanks,

Alex

All images have a strong green/magenta color cast.

Just wanted to say thanks to the screener who fixed the night shot category on my shot earlier today instead of rejecting (https://www.jetphotos.com/photo/9371007). I appreciate it!

Happens a lot more than people likely realize (I correct 20-30 images a day probably), you're welcome in any case

Everything in that photo seems to say CCW rotation is needed. Does the runway really slope that much at YHM?

Nah, it's only about a 0.1% gradient. I would have been happy to take the runway as level, but then the fence post would look tilted and I suspect I'd be asking for rejection advice all the same.

Hello,

the following photo was recently rejected for Horizon Unlevel: https://www.jetphotos.com/viewqueued_b.php?id=7369432

When submitting I added a note explaining that I chose to use the fence post as a vertical reference. The rejection email contained no comments from the screener so I do not know if the message is that:

a) the crew thought the fence post wasn't vertical enough, or
b) the crew thought that some other feature (e.g. edge of grass or rwy) should have been used as a reference instead
?

The following was rejected for Categories Wrong or Missing. No comments were provided and the system does not allow me to check what categories were selected. Can someone from the crew advise:

- what categories were selected
- what categories should have been selected

Thank you,

Alex

The only category needed is “Airport Overview”

Yeah, the compression was just an assumption, not a certainty, as to what was causing the blockiness of the effect.

Thanks for looking Dana.

As far as the magenta blocks in the equalized image go, I've been looking for a while and eventually found the culprit last night. It was the automatic CA correction in the RAW converter that was on by default. The linear borders of the artefacts are a function of the way the algorithm works, breaking up the picture into segments (to questionable effect in this case).



(Auto CA correction, no VigC)

If this photo was rejected for Over-processed I would disagree as well, since the artefacts aren't visible in the actual image. I wouldn't have made a thread about it however, since I see a world of difference between the Digital Manipulation rejection and every other kind of rejection.

P.S. I'm surprised at your comment about the compression. To me it's generally a balancing act between noise in the sky and compression artefacts. Without seeing any banding or distinct blotching (over the size of 3-4 pixels) I would have thought this one is well within the gate for that criteria. Any further thoughts on this would be appreciated.

Thanks for sending the RAW file; after taking a look, I can see that effect was almost certainly unintentional, and cause by two things. First, the lighter areas on the left and top of the frame are a result of some poor vignetting removal, or other poor processing on your part. The fact that they are quite blocky is likely due to how compressed the image you uploaded was. If I were to re-screen the image, I would change the manipulation rejection to overprocesed and (maybe compression) instead. I processed a jpeg from the RAW file you sent, with no editing other than cropping. Compare the equalized versions:

What you uploaded


What it should have looked like with no processing


Should be clear to see somewhere along the line (likely in an attempt to correct vignetting as I said above) you overdid the processing a bit, resulting in the brighter areas along the edges.

I appreciate your reply and need more clarification: What kind of digital manipulation could the magenta blocks (in the equalized image) be indicative of? I.e. is the thinking of the crew that I copied and pasted some sky into my photo?

I don't want to come accross as overly pedantic but this is an important issue for me, especially considering the nature of the rejection.

Alex

Edit:

To be clear:
- the photo was not digitally manipulated, have the RAW file to prove it
- the photo required minimal processing. All processing (except perhaps sharpening) applied to the entire frame
- the blocks visible at equalization are artifacts of the RAW conversion

If you want to send me the RAW file, I can take a look. I've never seen such patterns in a RAW file before, but I'm willing to take a look to see if that is in fact the case.

Indeed, bad edit of the sky on the left and top edge of frame.
