I believe it is posterization. If you open the image in Ps and click on the "info" tab in the histogram window, you'll probably find that the values change by exactly one when you move the cursor...

I've always felt that Adobe's upgrade policies have been fair and I have upgraded regularly, though not every single version. This change really sticks in my craw, for several reasons:
- It forces...

Just look for an M42-to-EOS adapter. They are out there. I also have a Peleng 8mm fish, and I use it on the original 5D. Mine is an M42 mount, using an adapter. I've had it the better part of a...

David, I agree with agavephoto's comments. I think this is a really good result for 15-second subs and moderate processing. Things sure are different than in the film days. Even my 5D Classic does...

Ye gads, beast is right! What incredible musculature. I would not want to get in his way, no not at all. -- 'Life is pleasant, death is peaceful; it's the transition that's troublesome' - Isaac...

Yep, buy either the 100/2.8 L or the 180/3.5 L and don't look back. The MP-E65 is a great lens, but very specialized. I shot for years with the 100/2.8 Macro, and I still own it, still love it. I...

Keep the lens in the front-element-down position. Remove the filter. Put the lens somewhere warm, and leave it for several days to make *sure* that any remaining moisture has evaporated. Don't try...

I have owned the original for a few years, and I love the results it gives. If I did not own it and were in the market today, I would certainly pick up the 24/1.4L II, given the relatively modest...

No one seems to have posted the obvious exception, so I will. Yes, lenses of (truly) equal focal lengths will have the same angle of view... as long as they are rectilinear lenses. A 15mm...

I love opening this lens up when photographing people/events in low-light situations. At 24mm, the DoF actually is not that thin at distances of 10 feet or more, and I still can get beautiful...

On a budget, the 85/1.8 and the 100/2 are of course the relevant choices... not there aren't other fine choices in that range. I think that optically both of these choices will give you reason to...

I also had read the letter some time ago. There is no doubt that the data is real, although there are no error bars presented, so we don't know how confident they are in said data. Question: Does...

There might be any of several reasons, or a combination of reasons, why you are about 1 stop low in exposure: - The Camera's sensor is actually less sensitive than ISO 100 when set to that...
