Quick Tip: Why Calibrate My Monitor

Calibrating your monitor.  What can I say?  We all try to get away with calibrating our monitor by eye, but that only works for so long and unfortunately our eyes change.  Not just over the years but throughout the day.  We get use to seeing a certain way and we adapt in different lighting situations.  In the end our paintings, photos or what have you suffer.  Our darks are too dark, the colors are to saturated or the hues just don't look right especially when we go to print.  So we are left to buying hardware to calibrate our monitors.

8 or 16 Bit Color Depth For Digital Painting

The question to use 8 or 16 color continuously comes up. I have tried to get a definitive answer to this question, but found nothing concrete. I have been using 16 bit for some time now. Mostly due to the advice of a friend who happens to be a professional photographer. I have to say I don't really notice a difference in my paintings, but I kept at it since it might help with better print results. This question wouldn't be coming up again if it weren't for the fact that I am looking to move to a Linux environment. Unfortunately I use Photoshop and Adobe only supports Windows and Mac OS's. But the alternatives,such as GIMP among others, only support 8 bit color. So do I really need 16 bit color?
