If you ditch photoshop you dont need a fancy computer. I used Picture Window Pro, its a true 16 bit editor and very fast and easy on rescources comapared to photoshop. What is good in photoshop are some plugins like PK sharpener, also layer masks, the healing brush, history brush etc. You can do without all those things but they are nice. How big do you want to print? Thats the printer you need, search on ebay for a 2nd hand one. You dont have to have the best of everything to do good work, just the will. Just the same as cameras and lenses, make the best of what you have already. The stuff you need can be had for much less than a 7x17 Korona, lens and holders. What you need most of all is beginners mind, and that cant be bought at any price. Its really good to learn something new but I suppose its hard to put the good results aside from an already purchased ULF camera and take the plunge into that cold water. To be a complete printer and printing teacher in this modern world its something that needs to be done.
