I hope I am in the right place - wasn't sure if this came under software or printing, but here goes.
I had 25 or so Jpeg images I wanted to have printed. The images were taken on a Nikon D70 in Jpeg format, not Raw.
Some of these I cropped using Nero Photosnap Essentials - the only thing I did was crop the images; I did no other manipulation. I saved the cropped images with the same name as the originals but with the word CROP on the end.
I then uploaded both the original images and the cropped ones to UK online photo print service Photobox.
I've used them many times in the past, and had cropped images printed with no problem. The results are always good and the service is unbelievably quick.
When I got the printed pictures through the post, all of the cropped versions were much darker than the originals. I am not a photography expert ( in fact the Nikon D70 wasn't mine ), and couldn't understand why this would be so. They are not just slightly darker, but much more so.
I looked back at both sets of jpegs on my PC, and also on the online album which I had uploaded them to. They look OK there. I also printed out a couple to see if this happened using my own printer, and it doesn't.
So I emailed Photobox about this, and they replied thus:
Thanks for your email. The darkness of cropped images is due to something called 'EXIF'. This is information held in a JPEG file that indicates things such as the camera that was used to take the photo, the date and time, and the settings used on the camera. If the image has been edited (cropped for example) then the editing software is also included.
When the printers identify that an image has been edited, they print the images 'as is' i.e. they make no adjustments to the image at all prior to printing, However, if no changes have been made, they will sometimes.
Can anyone make any sense of this ? I can't help thinking there's someting missing from the answer. But is it correct that cropping the image will affect the Exif information in such a way as to render the image darker when printing it out using a professional print service ?
I just want to have the proper iknowledge to hand before I reply to them, as it just doesn't sound right to me - but I may be wrong of course. Also, would my choice of editing software (Nero Photosnap) make a difference. I don't normally do much to photos before I get them printed, and the only reason I used the Nero sotware was that it just happened to be on the new laptop PC I have.
many thanks in advance for any input anyne may be able to offer !
