Thank you croowe and all.  I saved that tut.  One last thought:

My general rule of thumb is to not gotoo much below 150 dpi for a printed image. 100DPI if I was going to push it. Just depends on the audience

I think I understand what is happening with printed output as it decreases in dpi.  What is the "depends on the audience"  Pls example what would be needed as fine art for framing as opposed to poster board for backdrop display in some sort of business presentation.

Again apologies, but this is what I like about this forum.  Such a wealth of knowledge and "been there, done that"
