Need Help To Get It Right

Fri Aug 10, 2007 6:13 pm

From time to time I upload a photo to Airliners.net. In the past I managed a couple of times to get past the screeners and get the photo posted. My last photo posted is already a while back (2003) and I guess the minimum required quality has been raised substantialy since then, given that in the last year every photo I upload has been rejected.

I am the proud owner of a Nikon D80 with a Sigma 17-70mm F2.8-4.5 DC MACRO and a Nikon 70-300mm f/4.5-5.6G AF-S VR. As far as equipment goes, I bellieve that this set should be able to produce pictures that withstand the highly critical (too critical sometimes?????(not meaning to bash)) and all seeing eyes of the screeners.

Convinced that I finally got a winner, last week I uploaded this photo
Big version: Width: 1600 Height: 1082 File size: 267kb


In CS3, I brought up the levels a bit, used the "Smart Sharpen" function and resized to a width of 1600pix.

This morning I recieved the rejection-mail as I've seen dozens of times.
Eventhough the mail kindly states that "....everyone has their photos rejected from time to time....", it is getting a bit frustrating by now, because I no longer know what to do to get it right.

The picture was rejected because of "Blemishes" and "Too much grain or digital noise".
I really don't see it!  eyepopping 
So I would much appreciate it if you people could explain to me what's wrong with this photo and how I can improve it in the future.

Just to be clear, this post is in no way meant to question or critisize the A.net screeners, I just want to learn and become a part of the frequent uploading A.net photographers.

Greetz,

Hi Frank!

The screeners were still quite nice (or lazy  Wink) when rejecting only for dirt and grain; in fact the following reason would apply too: center, contrast or simply a quality rejection.
First of all you need to downsize your pictures to about 1040x700; this will make the picture look much better in quality.
You can find the exact required sizes here:

along with other useful uploading hints.

Hello Thierry,

Thanks for this quick response. Please elaborate a bit.

Quoting ThierryD (Reply 1):
center

What's wrong with the center? This was no crop. I shot the photo as is. If you mean the aircraft is too high in the picture, in total perspective of the picture, I thought it quite nicely fits the composition.

Quoting ThierryD (Reply 1):
contrast

Do you mean to high or to low?

Quoting ThierryD (Reply 1):
simply a quality rejection

Now you lost me. Please explain.

Best regards,

Frank

First of all, your shot should also get rejected for blurry, centered and level. As for your equipment, its fine. I also have a D80.

For uploading, i would never do 1600 pix wide, more like 1200 (what i always do) or 1024. That way the screeners will see less quality issues. What modes were you shooting when you took the shot? ISO, camera settings, etc.... because it does have lots of noise in it. Also, next time centering the shot before taking it can probably save you from a centering rejection.

blurry

 confused  which part  confused 
The aircraft looks perfectly clear and sharp to me.
Not to discuss your opinion, just trying to understand.

Quoting DM (Reply 3):
ISO, camera settings

Shot this photo at ISO100 in the S(hutterspeed) mode. Shutterspeed is (IIRC) 1/250th and the aperture was around f/5.
Have to check the original EXIF data for that to be exact.

It's far too high in the frame for A.net standards; aim to get the middle of the fuselage into the middle of the frame.

Too much contrast. (further explained here: http://planecatcher.com/IGRR/Contrast.htm)

Quoting 747ata32 (Reply 2):

When several factors come together, like in your picture (dirt, contrast, grain) screeners sometimes just give a quality rejection to tell you that the overall quality doesn't meet A.net standards. Up to you to find out then what exactly is wrong.

Too high, look at the bottom of the fuselage and you can see the darker areas that have been hit with too much contrast.

Quoting 747ata32 (Reply 2):

Noise, grain, blemishes, dirt, blurriness, all fall under "quality"

Quoting 747ata32 (Reply 4):
which part

Slightly in the nose area.

Now that i think of this it should have recived a editing rejection too! You have cloned out a dustspot (i think) near the right wingtip that has actually casued it to clone the wingtip also making it look like there are two wingtips!

Nope. Did not clone out anything on the photo. What you see above the righthand wing tip is the tip of the righthand horizontal stabilizer.

Quoting DM (Reply 6):

So is there a way to select only that part in PS and sharpen it a bit???

On a general note, thanks so far for all the time you guys take in explaining to me. Slowely, things start to dawn on me.... a bit....

Whoa, that was kinda an illusion to me! Sorry!

Quoting 747ata32 (Reply 7):

Yup, If you click on the selective blur tool (looks like a drop of water) you can switch it over to a selective sharpen tool (triangular shaped) which you can then sharpen what you would like.
