I just love this hobby of photography and I'm delighted with the amazing things one can do in Photoshop.  
As there are not many people around here I can share with, I thought I'd share my passion, via this web site, with you.
Also being new to this world of post-processing and not really understanding colour (channels) and tones, I'm thrilled at how much one can achieve using Lab mode compared to RGB - it is the difference between juggling one ball at a time compared to two+, and so quite a few pages are devoted to how easy and powerful the Lab Colour space is.

These pages have grown over time and some of them are rather naff, as I put things up as I learn them, so you will have to pick and choose what is worth looking at!

Before you continue are you seeing what Im seeing? Can you see the full range of 16 evenly spaced grey boxes?

And how about this image you need to move back around 3-4 feet for a CRT screen and 2-3 meters for a LCD screen (and even then you may have difficulty getting the right viewing angle!).

If you see a band down the middle of the columns, then your gamma is not at 2.2 (best for the web and most cameras) - if you are using a LCD screen, then notice how it changes as you move your head around.

Now looking carefully, close up, you should be able to read the numbers 248 and 252 in the top right corner of the white bar and the numbers 8 and 12 (even 4 if you have an excellent screen) near the red/green bars in the lower black horizontal bar.  The background and the grey patch should be neutral grey.

If you cannot see these numbers, then your screen is not showing shadow and highlights properly.

Does it really matter that we are not both seeing exactly the same tones and colours?  Well yes and no!  
If you are only ever going to look at your pictures on your screen, and do not mind that your the prints are slightly different - then leave things as they are.  If you have a laptop, compare it with another screen (both showing the same picture).  If the colour difference is small, then live with it.

However if your prints dont look like your screen, then the best thing to do is to adjust it.  Think of the problem as the screen's White Balance.  You know if the camera's White Balance is wrong then your picture comes out with a tint in it - well the same is true for screens.  

I could never get photos of people to print correctly, the faces were always too red - it was very frustrating and so I rarely printed anything and if I did, then it took me ages trying to correct them.  In the Computer Related pages I show you how to adjust the screen's Gamma - and then your screen will be properly balanced.   By the way if you run a Mac, then this need not apply to you, as the Mac gamma is initially set at 1.8!

Incidentally, you can save any of the images, by right-clicking on them and selecting Save Image As
