I want to replace my old, 2-buttons, ball mouse with something new that is better for work with PS and I need your help. Do you have any favorite mouse or trackball to work with? Are cordless mice more convinient than corded and how precise you can be with them? I found more of gaming mice on market than one designed forphotographers. Is wacom 4x5" tablet worth buing, or just a mouse would be enough? I am not a professional photographer and I do mostly basic PS adjastments.
I find a graphic tablet far easier to use for image editing than any mouse, but other posters find a mouse sufficient. Most basic work such as curves/levels can be done easily with a mouse, but as soon as you start talking about cloning out dust spots or making selections & masks a graphics tablet is ideal. Using a stylus on a tablet is far more intuitive and direct than palming a mouse, at least for me.
I've never had the chance to work with a graphics tablet, but I can recommend the Microsoft CORDED optical mouse. It's nothing fancy, generally inexpensive, accurate like you wouldn't believe, and reliable.
I use a kensington turbomouse...which is a TRACKBALL:
I had the opportunity to test out a lot of devices, and this, to me, gets everything into one device. The only thing a tablet can really do is pressure control. But for my skills, this item is better as I am not good with a pen...I have far greater control with the stability and size of this ball, and there is no annoying lift-and-move like you have with a mouse, and it has a smaller footprint on the desktop.
I started using this in about 1995, and I've tried other things since (even other products from Kensington) but this is the best I have used. It may take a week or two to get used to, but once you do it is very intuitive. My three-year-old (at the time I started getting her used to computers) had the option of mouse or trackball, and she used the trackball by choice, and it looked so much more natural.
