Welcome to Understanding PS CS5
Understanding Photoshop CS5 is a read only blog as this is only to show you the ins and outs of the programme. Photoshop in it's self is an intense graphics programme and I will try to explain what every feature of it is. This will be long and the information will mainly come from myself from years of using it.
This is for CS5 but I am sure that you can use the information here for earlier and newer versions of Photoshop. Everything you will need to know will be in pages to your right so navigate to what you want to view.
Anyway I hope that you find this useful and the image used for the text comes from CS5 itself with me messing with CSS to look like it is now. It was not easy I can tell you and an experiment that worked.
This will not get updated as remember this is a read only blog to help you understand Photoshop CS5 if you are absolutely new to Photoshop. I use a White Rabbit version of Photoshop.
