Histogram Edge

[jeffjeffreyjeff]

I have a difficult time determining exactly where the left/right edges of the histogram are, because there's all black screen around it, and no graduated marks for the far left/right sides.

Does anybody have any tips, short of overexposing a test shot and physically putting something on my computer screen to mark the edges?

Thanks!

I have never had a problem with visualizing where the ends of the histogram are. There are several controls above and below the histogram which line up similarly. The histogram is divided into thirds so it is easy to measure by eye the width of the left and right sections from the width of the center section. Finally, the width of the right section is bordered on the right by the curve stretch tool.

Remember this is not a true histogram of your raw data. It is a histogram of the JPG thumbnail that is embedded in the raw image.

It's all inside the histogram box control, with a 4 pixel padding on wither side... it's pretty tight.

However, this should not be an issue as you need to say clear of the edge anyways and your histogram hump should be pretty well inside about control.

If you really want to know for your own sanity you could try and take an under exposed flat barely enough for the the histogram to show on the left side and then note where it start vertically and then do the same with an over exposed flat and note where it cuts off on the right side.
