Hey all, I'm in the middle of developing a portfolio, and for one section of the portfolio I am going to include a series of rough sketches. The only problem is that some of the sketches are drawn in simple graphite, while some are in blue pencil. I'd like to make the graphite sketches blue like the other sketches. Is there an easy way to do this in photoshop? Thanks in advance

you can adjust the "Hue and Saturation" (*ctrl+U*) and then click "colorize" ... move the sliders to get the colour you want, and adjust the "Brightness/Contrast" (*Layer --> Adjustments --> Brightness/Contrast*) to sharpen the blue and clean up some of the white... if you want to include some strong black into it also adjust the "Levels" (*ctrl+L*)

Thanks a lot, I'll try that when I get home!

You can also use "replace color" with the advantage that the background won't be affected (depending on the threshold setting of course)

Or you could use a Gradient Map of blue and white.

I'm late to this, but another way is if you're using a layout app like InDesign or Quark, keep your drawings in b/w. When you import them into the layout app, there are ways to make the image be colorized there, i.e. anything black is changed to whatever color you choose. There are tutorials for each program at their websites as this is a pretty basic feature. :m
