Overclocking Photoshop colours

Posted in Humour, Photoshop, Technology by uninformedcomment on June 23, 2009

Did you know it’s possible to overclock Photoshop’s RGB colours, as well as those of most other graphics programs?  I found this out today from the internet, but when you think of it, it’s obvious.

Most of the tutorials you’ll see, and indeed the official reference guides, say that the maximum value you can have for an RGB channel is 255.  But that’s a computer number, and computer numbers are multiples of two:

1, 2, 4, 8, 16, 32, 64, 128, 256

Yes, 256, not 255.  So why do they say 255?  It turns out that they’re concealing the truth as a kind of Easter bunny for you to discover, but most people never try colours using 256, and the world of graphics is all the poorer without the extra hidden power it gives us.  So I’m breaking the silence, and showing you how to unleash the full potential of your graphics card and monitor.

First, set the red, green and blue channels to 256 by typing the number into each channel on the colour picker:

Overclocking RGB values

Notice how the foreground colour (256, 256, 256) is noticeably brighter than the background (255, 255, 255).  It almost hurts your eyes!

Now you can use this power to get brighter colours in all your artwork.  Just look at the lovely white smile on this lady:

WARNING:  May cause overheating of VGA cables and connectors due to the increased voltage necessary to display these images.  In computer terms, 256 is double 255, remember?  Also, don’t leave your monitor switched on while you’re displaying overclocked images – you’re not only wasting power, you’re also in danger of fading any valuable old paintings in your room.
