Thanks for the input. i reshot today and did an experiment. When I used asa 1000 at 1/100 sec no problem, but as i increased shutter speed to 1/850 the yellow appeared on the edge, and in the middle.It seems to indeed have to do with the freq of the lights and the shutter speed. However I am still not sure if its only my camera, I need to have this shot with another 1 ds and see if the same thing happens.I have seen alot of shots done in a gym, and with gymnastics you need a fast shutter, but I dont recall seeing this problem befor. Please let me know if anyone did a similar test. i hate to imaging its just my camera. Thanks for the input, nick

I have acanon 1ds mark 11,16.7 mp. Recently while shooting indoor sports I

noted 1/4-1/2 frame of random photos there was a yellow discoloration along

the long axis of the image.( It was not a dirty sensor or software proble w

photoshop.) it was not on each image. It also could not be from a different

temperature of light since 3 frames shot at the same time and only 1 frame had

this. It was sort of like when the flash sync was off on film camrea. I was

shooting asa 1000, and it was most apparent on the 85mm 1.2. It was not always

on the same side of the image, it was sometimes in the middle. Anyone else

seen this?It does not seem to happen on outdoor subjects. The lenses are clean

as well.
