As was done a few months ago, I am reposting the reasons the screeners have for rejecting pictures. Some of the text (and reasons) have changed, and have hopefully become a little more transparent, giving the recipient a little more explanation as to why his (her) photo was rejected.
Please note that the Size reason is a little out of date. Portrait-format pics are now accepted up to 1024 pixels tall. Johan will get around to updating this soon.
Comments are welcome, of course. I hope this is helpful to you guys.
$baderror_text = "
An error occurred then trying to process these photos. Probably caused
by an incorrect filename. Note that our scripts cannot process files
whose names include \"jpg\" or \"jpeg\" in the main filename (before
the dot). Example: 747jpg.jpg would not work. Furthermore, the filename
needs to be shorter than 50 characters and reasonably original (1.jpg
would be a bad filename). ";
$badcopyright_text = "
Please do not add any text or graphics to your photos. A small copyright
notice (your name & e-mail) in a corner is recommended but remove any
other text or graphics from your photos (Including URLs). You will find
more info in the Upload-FAQ. When done, please re-upload them.";
$badblury_text = "
The photos were blurry. Look carefully at your original picture/slide.
If it is sharper than the uploaded file, you might try using a photo
manipulating program like Photo Shop or Paint Shop Pro to sharpen the
images, using the Unsharp Mask, Adaptive Unsharp, or Sharpen tools. Most
scanners will not provide a very sharp image without such post-scan
manipulation. If the original image is not sharper, this might be caused
by the camera, the light conditions when you shot the photos, object out
of focus, improper photo manipulations or any combination thereof.
If you think you have been able to improve the quality of the photos,
please re-upload them. Note that we are still very interested in having
these photos in our database, we only ask that you try to improve the
quality of the digital version of your photos.";
$badcontrast_text = "
The photos seem to have been scanned with a too high or too low contrast
setting. Please change the settings on your scanner or use a photo
manipulating tool to improve the contrast. (High contrast = dark areas
are very dark and light areas are very light.). A more sophisticated (and
possibly more effective method is to adjust the black-point and
white-point of the image, where you manually define which areas of the
image should be absolute black and white, and let the software adjust the
rest of the image accordingly. When done, please re-upload your photos.";
$baddouble_text = "
These photos have already been added to the database or you have
previously added photos that look very much like these. Please read more
on this issue in the Upload-FAQ.
Note: You could also get rejection message if there are photos very similar
to these that have passed the first screening and are waiting for the
second, final, screening.";
$badcolor_text = "
There is a problem with the color in your photos. You could get this
rejection message for one of two reasons. Either there is a strong color
cast that makes you photo look too red/blue/yellow etc. or you seem to be
using a low color depth in your photos.
Please check the settings on your scanner (High DPI and color depth) to
ensure you are using 16 bit colors or higher. You might also experience
problems with poor colors if you use a too high compression level when
saving your jpeg files. You should also have your monitor and video card
properly set up for 24 bit color or higher (usually called \"true color\").
Windows users can easily check this by right clicking on the desktop and
looking in display settings.
Color casts can be caused by the light at the time you took the photos, or
any problem with color settings when you scanned or edited them. You can
usually fix these photos by simply adjusting the red/green/blue settings in
your photo editing program. Try comparing the colors in your photo(s) to
some of those already on Airliners.net.
If you are scanning very old pictures, particularly (but not limited to) E-6
slides more than 20 or so years old, there may be a very strong color shift.
Some of the more recent scanning and photo manipulation software have
specific functions designed to restore the colors of old pictures.
If you are scanning prints on a flatbed scanner, this may be the result of
\"corrections\" frequently made at the photo lab. These \"corrections\" are
especially harsh on aviation photography. In this case we strongly
recommend that you either change photo labs, or ask your lab to develop
your pictures without using any color correction (some labs will do this

$badphotog_text = "
Something about your upload or the attached information leads us to believe
that you may not be the actual photographer of this photograph. You may get
this message especially if the photograph appears to be a \"high
production-value\" photograph, such as air to air shots requiring significant
airline cooperation and expense. You must have photographed the photos
yourself to add them to Airliners.Net. This is very important due to the
copyright issues involved. If you want to upload photos taken by friend,
mail us and we'll let you know what to do. To upload photos you do not own
the copyrights to is a violation of international copyright laws and may
cause huge fines or jail depending on severity and country. If you are
the photographer, please indicate this in your remarks.";
$badscan_text = "
The image quality of these photos are low. This may be the result of several
perceived problems happening simultaneously, such as grain, blur, lighting,
contrast or color defects, which would lead us to believe that a fresh scan
would be necessary, rather than a simple adjustment to the uploaded file.
It could be caused by the scanner you are using, the way you scanned your
photos, the (digital) camera, the light conditions when you shot the photos,
object out of focus, improper photo manipulations or any combination
thereof. Most of the time, the cause is either a bad scanner or that the
scanner wasn't used properly. If you think this might be the cause, please
read the documentation for your scanner and find the best DPI and color
settings. Generally a higher DPI and color setting will make a higher
quality image but only to a certain degree and it differs between different
brands of scanners. Try many different settings until you find the best
combination. If you are using an old or low quality scanner you might
consider investing in a new or borrow one from your friend/workplace/school.
If you are using a digital camera, check camera settings.
A frequent source of this problem is when the photograph was taken under
poor weather conditions without appropriate corrective measures (such as
exposure). Note that making acceptable photographs in poor weather
conditions or at night is quite difficult, and you should perhaps try to
achieve a good level of expertise and a few successful uploads of good
weather photographs before attempting much more difficult poor weather

of photos with a high quality scanning in out \"Editor's Choice\"
section linked to from the front page of Airliners.net.";
$badsize_text = "
The size of the photos are too small. Please scan your photos about 1024
pixels wide and 768 pixels high for landscape format photos, or 768
pixels high for portrait format photos (with a high DPI and color depth

(for landscape-format pictures) is 800 pixels across.";
$badinfo_text = "
Some of the info you submitted together with the photos was either
missing, incorrect, irrelevant or in the wrong format and we were
unable to correct it. A common reason for this message is where the
registration appears to have been legible on your original picture,
and the registration was not typed into the appropriate box on the
upload form. You might also have marked incorrect categories for
this photo. Please re-upload the photos and pay high attention to
supplying correct info. You will find more info on this issue in

together with the photos was either written in a non-English
language, misspelled or used capital and lower-case letters in all
the wrong places. Please re-upload the photo and pay high attention
to spelling and whether to use caps or lower-case. (General rule:
Never use all capital letters).";
$badmotiv_text = "
The photos were of low esthetic qualities - bad angle, included
window reflections, pictured just a part of an aircraft, out of
focus, distracting or obstructing objects in the foreground or
similar, pictured an aircraft far in the distance or did not
picture an aircraft or anything sufficiently related to aviation
at all. Finally, you might read this because your camera displays
the date in the lower right corner of the image. If so, please
disable that feature in the future.";
$badpeople_text = "
You need permission from the people pictured on the photo to be
allowed to publish it. Generally we do not accept photos with
people on them as our database is primarily for airliners. There
are some exceptions though. The rule essentially is that the
primary subject of the photo must be the aircraft, not the
person. If the person is clearly recognizable (facing the camera,
clear mention that permission was given by that person must be
stated in your remarks.";
$badborders_text = "
Please remove the borders that partly or in full surrounds these photos.";
$badcentered_text = "
Either part of the aircraft is not visible on these photos or the
aircraft is fully visible but not centered. If the aircraft is
fully visible but not centered, you might try to crop the photo
so that the aircraft is centered.";
$badcameraangle_text = "
The angle of the camera does not seem to be straight compared
to the horizon. In the future, make sure you always hold the
camera absolutely level. This particularly applies to pictures
of aircraft on the ground. For shots of aircraft in flight where
the ground is visible (take-offs and landings in particular),
the general rule is that the camera should be level with the
horizon and the aircraft be at an angle. There may be
exceptions to this rule if the composition of the picture is
unique and having a level horizon would detract from the
aesthetic value of the picture (such cases will be rare).
Such problems can often be fixed by carefully rotating and
cropping the picture. If you think you have been able to
improve the photos, please re-upload them. Note that we are
still very interested in having these photos in our database,

correct categories. Please re-upload the photos, making sure
you select the correct categories. If you are unsure which
categories applies, read the Read Me link situated beside
each category button on the upload page. Note that several
categories, such as special or hybrid color schemes, are
ONLY for airliners.";
$badgrainy_text = "
These photos are too grainy. Try using your photo software's
feature to reduce. Adobe PhotoShop has a special feature on
reducing grain. Grain is often caused by too much sharpening,
flat, uniform areas (such as the sky) are particularly prone
to becoming grainy if too much sharpening is applied. Certain
films, particularly high-speed films (anything higher than
100 ASA) have more visible grain and poorer color performance
than slower films (100 ASA or lower)";
$baddistance_text = "
The aircraft pictured in these photos are too far in the distance.
In the future, try getting close to the aircraft or use more zoom.";
$badcompression_text = "
Too much JPEG compression. If your photo is wider than 1024
pixels or higher than 768 pixels it will be downsized and
that might lower the picture quality. Keep the width on
exactly 1024 and save with minimum JPEG compression and the
quality will be at it's best. Do not worry about long download
times for low compression files, our scripts will automatically
optimize compression without loss in picture quality. Always
save your photos with the lowest possible compression. As a
general reference, the size of a JPEG file without any
compression, of 1024 pixels by 700, will be somewhere in the
range of 400-700 KB, depending on the composition and color
$badjagged_text = "
The transition between foreground and background on these
photos give a very jagged impression. This often is the
result of too much sharpening. This is generally most
evident on solid lines such as wing leading edges,
particularly if several lines are close together, such as
gaps between the wing and flaps, or cheat lines spaced
closely together. Try increasing the DPI and/or
eliminating any JPEG compression. You might also try using
a smoothing filter, or selective use of masks to avoid
excessive sharpening or areas where jagged lines may

There are a large number of pictures of the aircraft you
photographed already on the database. In such cases, the
standards for acceptance are higher than for planes of which
we have fewer or no photographs on the database. In this
case, we will only accept pictures which are of very high
quality, or otherwise of an unusual nature.
Please understand that this is not a judgement on your
abilities, as your picture may be of a technical quality
which may be, on the whole, acceptable. However, due to
the common nature of the aircraft photographed, the highest
standard is applied to avoid substantial duplication.";
$baddirty_text = "
The scan is very dirty. This may be caused by a dirty scanner.
For a flatbed scanner, use lintless cloth and window cleaner or
other appropriate glass-cleaning product to clean the scan bed.
For film/slide scanners, try using compressed air to blow out
any dust. This message may also appear if there was dirt or
scratches on the slide or negative. Always try to clean away
small particles with a very light brush or compressed air before
scanning. Dirt that finds its way into the final scan can often
be repaired by using the cloning tool available in most photo
