Hi all
I have been reading about digi photography and my D70.
Is there any way we can perhaps organise a workshop so that one of you experienced guys can go through these things and how to read/adjust settings in reference to a histogram?
I have rapidly gathered that being able to read a histogram for a pic you have just taken can make it extremely easy to make sure your exposures are correct but just cant quite get my head around them
What do you all think?
thanks
Glenn

Perhaps this workshop could be put into PDF format and uploaded to the Tutorials section.. so all of Australia (and perhaps the world) can enjoy... not just those horrible horrible Sydney folk!

Good job I'm not from Sydney. Much better that I'm a horrible, horrible Newcastle person

IMO the Ron Reznik book is the definitive for histograms

Perusing the Important Links section of this forum will come up with various websites and tidbits on histograms. Work through them at your own pace, and then at one of the meets you can start teaching us Glenn.

A histogram has to be interpreted in relationship to the subject. This means that it often not easy to decipher. However, for most "average subjects" it should be broadly spread and as close as possible to the right hand side but without touching the right hand side. This providing there are no specular highlights in the image. A specular highlight is a flash of light off chrome or water and is the same white as the paper the image is printed on. It has no detail whatsoever. I will put a powerpoint presentation together and make it available via this forum in the near future. The subject probably does not warrent its own workshop because it is too difficult to lock down any given rules in general photography and because the histogram can be used only as a guide.
