Coral Draw 8

Fri Mar 23, 2001 3:35 am


I have Coral Draw 8 and I find it very hard to sharpen without having dots everywhere, my photo quality is at it's best, I use a Kodak Gold Zoom 800 and a 200. I use the 800 the most and the photo quality is fantastic but when scanning it isn't the same, I have done everything I can to adjust the dpi etc on my scanner. Can anybody give me any tipS?

Hello EGKK,

I am a pretty new guy here with aviation photography, but I have had a fair amount of experience with Corel Draw 8 (Photopaint). I think it is a fantastic program. I am always trying to sharpen images on Photopaint since I don't have a fancy zoom and SLR, and I have had mixed success. A few things I have found is that any noise (or even if you don't have noise) in the photo will get accentuated with the normal sharpen command. To be honest I never use the sharpen filter becuase, like you said, it ends up covered with dots. Instead, I get the best results with sharpening when I increase (temporarily) the dpi of the image using resample command from 72 to 130 or something (not the dpi of the scanner, but of the image, if you are following me). Then I use unsharp mask (under the sharpen menu under the Effects bar), trying different amounts of radius. Also try additive unsharp. I recommend anything EXCEPT sharpen in Photopaint 8. It also helps to pass a remove noise filter, if you are having a lot of problems with that. When you have it where you want it, set the dpi back to 72. It can be tricky, but the bottom line is in Photopaint, unsharp mask and additive unsharp work much better than the sharpen tool. It is a fine line between just enough sharpen and not enough. If you find another way than is better than what I told you, I'd like to know as well, since that is the thing I spend most of my time time doing- sharpening!

Hopefully someone with more than my experience replies to your request, but I hope this helps in the meantime!

The answer is in your question.
Drop the Kodak Gold Zoom 800 and a 200.

Try not use high speed asa films.
Go down to 100asa, no need to go any higher.
I was using fast speed films for years for my prints
but they're just not good enough for scanning.

Also when unsharp masking, I think the norm
is to keep the radius low, threshold quite low and vary the amount
to taste!

I'm sure others may add to this....  Smile/happy/getting dizzy
