No Mountain in Photoshop Curves

[Fordos Moon]

Hi guys. When I use Curves in PS I have no visible mountain / histogram to use as a reference.

When I click on the image I get the temporary circle on the diagonal and an adjust from there but no visible histogram.

Picture attached, your thoughts please!

maybe the historgram is present but too stretched out. (I don't have PS, but I've experienced this in other packages)

On my curves box there is a button for display options, open this and make sure histogram is ticked............

Got a feeling my old version of PS doesn't have the option :-(

It was added in either version CS2 or CS3 (it's certainly in the latter).

I use CS2 and the histogram isn't shown. It really doesn't matter. So long as your line isn't hitting the top on the right and ends at the bottom left hand corner you won't be clipping. The histogram is handy because you can you can use it to easily adjust the black point from curves but not having it really isn't the end of the world.

Martin thanks for putting my mind at rest!

Although I have it I never use it. I find the histogram easier to see in Levels.
