I finally made a Google account .I will blog here not on the forum.Anyway I might as well post some things that i learned this unit so I can review it later.
A picture is made from thousands of pictures. A pixel is like a small dot of colour that make up the image. For websites the best resolution is 72 dpi (pixels per inch ) and for print the best is 200dpi. A low # of pixels will make the picture loose quality.
Rule of 3 : draw an imaginary tic-tack-toe style line on the picture which has 9 parts . At every intersection of the lines something has to happen there or very close to it .
If an image has bad colours like they look grey adjust the contrast and brightness.
There are a ton of tools in Photo shop , too many to list in a single blog but most of them are self explanatory like smudge - smudges the image, burn - darkens at click , Dodge- lightens the image where clicked etc.
Now I'm working on MR. Wiggles which is my new "masterpiece" made in photoshop from scratch . It's an abstract arm although you might see a germ in there.
