Jacko mentioned, in another thread, that some sites will disqualify an "original" image if the image data has been rotated. I have been using GraphicConverter or iView MediaPro to do a lossless rotation on my original images rather than keeping an original and a copy with rotation. I create a copy before I edit an image, but is seems like wasted space to have a duplicate if the only change is lossless rotation. There is nothing at risk for me, because I haven't come near winning a challenge, but if this is a bad practice I should probably stop now.
1) Will this cause a disqualification onf dpchallenge?
2) Is it just a bad thing to do.
Any thoughts?

From the Challenge Rules:
If the validity of your submitted photograph comes into question, you may be asked to submit your original, unmodified photograph and steps to recreate your submitted photograph from your original photograph.
I would say even though the image data does not change, it is still technically an edited original, therefore grounds for DQ.
Edit: Just work from a copy and you won't have to worry. :-)

True, however some just "tag" the image so later on the software knows what orientation it is supposed to be in. This causes problems, since there's no standard for this type of tag, and usually only the camera manufacturer's software understands the tag.
Still, the best advice is, retain the original, right out of the camera, and work on a copy. Storage these days shold really not be a problem.

You are right about the tag in the jpeg file format. Unfortunately, most of the applications that rotate images do not reset the flag no it is easy to get the flag and the image out of sync.
The additional storage required for so many duplicate images became more of a problem with the 10D, but you are right about the cost of storage not being an issue any more. |
