Black and White Target Values in Paint Shop Pro?

tjsgarden · #1 04-24-2002, 07:45 AM

In her book Photoshop Restoration and Retouching , Katrin Eismann states:
"To get the most out of Levels you will need to set the black and white target values before beginning. This tells Photoshop which values to use for black and white."
Her instructions advise using the eyedroppers to set white, black and gray points. The problem is Paint Shop Pro does not have white, black or gray droppers in the levels windows. How can I quickly make these adjustments with Paint Shop Pro? I have tried the Manual Color Adjustment feature but that dosen't seem to duplicate the same effect.
THANKS for advice!
John

Hi John...

I know very little about Paint Shop Pro, but I was poking around and it appears the COLORS/Histogram Functions.../Histogram Adjustment has possibilities.

It graphically represents the tones in the image and although it doesn't have 'eye droppers,' it allows you to set the black/white points based on the histogram using sliders and your eyeballs!

Here's an article that looks promising, too...

Found this [and other articles] using the following search at Google.com:

Try this one, too:

Hope this is what you were looking for or at least gets you moving in the right direction.

I think DannyR has pointed you in the right direction.

I used to use Paintshop Pro but it's been awhile...

I would use Paintshop Pro's Historgram Adjustment found under Colors and then Histogram Functions and finally Histogram Adjustment: shortcut - Shift+Ctrl+H. Under Luminisity you will see three points mapped on the historgram. The far left is either dark grey/black, grey for the centre point and white on the far right. Click on the black arrow and slide it to the right a bit, it's a bit of trail. I do this with each color until I'm happy. When I'm finished there is a slider to the right with Midtones Compress at the top and Expand at the bottom. Move the slider up and down until you like the results. Here is a nice link and tutorial about Histogram Adjustments....

Here is a picture I worked on using the original - then Paintshop Pro with a histogram adjustment and finally Photoshop 6 with a levels adjustment.

Thanks Danny, Oh That Girl and Doug for your generous and helpful advice. All the info and links have been good. My web link has been down since last Thursday. Thats why it took me so long to reply.
Some good news!--- I got more RAM and a graphics tablet this weekend.
A special thanks to Doug for such a great sight!

Hi John
You will have to let us know how you like your new toys. Does the RAM make a big difference for you and how long does it take to get used to the graphics tablet. I know you will love that one. Good for you. I love getting new toys. (My credit cards reflect that too.
