« on: September 02, 2010, 11:16:35 pm »

please help me figure out what is wrong.  see photo in the the link "best of the day" and look at the grey that is turning purple.  i shot jpeg+RAW and this is in both.

it looks like a chromatic aberration but it has never happend with this equipment before...1ds mkii, 70-200L at f12 or f16 iso 100.

thanks for any help you can give me!!

Hi, if this is B/W where is the purple?

to the left of the subject in the first quarter of the frame....maybe it's my monitor.  I have a print coming in of the image sometime next week...we'll see if it shows up on there.  The thing is that it's not showing up on other images on that screen.

I could not see any purple, but after analysing the image I detected that it is not completely B&W, even if it looks so: most pixels have different values for each RGB channel. On the other hand, any chromatic aberration should have been eliminated while doing the conversion to B&W.

How did you edit the image? How did you do the conversion to B&W?

Did you flip/rotate the image to see if the purple moves?
