Or buy Photoshop Elements and choose the 'colorize' option? ;-) Photoshop is great but I do find it a little overkill sometimes. For most of my graphic manipulation I use Elements or Paint.Net!
Ta for sharing though Lisa, will file this away. Gordon -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Lisa M. (Bronson) Gielczyk (TCP) Sent: 22 March 2007 19:16 To: TCP List Subject: [TCP] update on changing color in graphics A couple of weeks ago, I wrote a question to the list about changing colors in graphics using PhotoShop. I have been working on this intermittently, and while I'm not quite done, I have learned a lot, and thought I'd share what I'm doing. (I think it's time to ask my boss to invest in a good PhotoShop book. Any recommendations?) I'm starting with a graphic of some bubbles. Most of it is fuschia and there is also some green and a very small amount of other colors in it. The target is to have everything in shades of green for one graphic, then two more graphics that are shades of yellow and shades of blue, respectively. These are the steps I'm following to get there: 1. Convert the original fuschia image to grayscale. The easiest way to do this is using Image>Mode>Grayscale, but I've read that there are better ways. The method I'm using: a. Convert the image to Lab Color. (Image>Mode>Lab Color) b. Go to the channels palette. c. Select the Lightness channel. d. Convert that channel to grayscale. (Image>Mode>Grayscale) You will be asked if you want to discard other channels. Click OK. I highly recommend you save the grayscale image in PhotoShop format and gif format at this point. 2. Use a duotone to add the color you want into the grayscale image (Image>Mode>Duotone). This process is not intuitive, and I have not found any good resources to figure out how to use this feature. But, by trial and error, I've been able to make the green graphic. a. Select two colors to make the duotone. I used black and a medium green to make mine b. Click the curve to the left of the color swatch to change how the colors mix and blend. (This is an extremely unintuitive part to me!) Click and drag points on the curve or change the numbers in the boxes. 3. Once you have the colors the way you want them, convert the graphic back to RGB or CMYK. 4. Save as a gif or whatever filetype you need. Clear as mud? That's what I thought. ;) Have a great day, Lisa G. ______________________________________________ Author Help files and create printed documentation with Doc-To-Help.
