I want to take screenprints and then be able to add a postbox effect to grey out all but a certain area of the screenshot. I wish I knew where I saw the example of this, they had screenshots in a tutorial and this effect made it all look so clear. I haven't able to find anything that does the same job.

Any ideas? Preferably freeware (I'm poor) and compatible with XP to Windows 7. Thanks for any suggestions in advance.

EDIT - for example, the "lights off" feature on It dims the entire page, apart from the video itself. It add emphasis and that's effectively what I want to do with screenshots.

You can use the free version of FastStone Capture (in a slightly round-about way)...

  1. Take a screenshot
  2. Select the area to be highlighted with the Selection Rectangle
  3. Invert the selection (Ctrl + Shift + i)
  4. 'Ctrl + B' for 'Brightness Contrast Gamma' then reduce the brightness slider
  5. 'Ctrl + D' to remove the selection rectangle

If it's a colourful image you can also try 'Effect > Gray Scale' so only the highlighted rectangle is in colour.

I can see after a little bit of time, this is going to become one of my best friends. Just what I'm looking for. Great find, thanks. – Kez Sep 9 '09 at 22:31

ScreenHunter 5.0 is freeware that can screenshoot your entire screen, a selected area, or just the current window with the press of one button.

I don't know what the postbox effect is but I'm sure it is something you could add after the fact if it is necessary.

I like the file naming scheme in ScreenHunter. It is highly customizable.

Windows 7 has the built in problem step recorder you can use and I highly recommend Snagit. There are free alternatives that are almost to Snagits ease of use and ability but not there at least in my opinion.

Opensource, can do selected area, highlight with box, etc. directly copy to the clipboard, open paint editor directly, etc.

I used it everyday, very good program.

Already accepted an answer, but I have to admit that I found something a million times better.

Screenshot Captor

After trying nearly every screenshot tool under the sun, I found this to be the most comprehensive tool yet. It has the ability to grey out all BUT multiple selections of an image. This is exactly what I was looking for. Definitely worth a look, not just because of the feature set but because the guys behind the software are very active in development of the software, moving it forwards.

I just wish I stumbled on it sooner.
