Not worth much. I usually prefer domains containing max 2 words. Yours has 4 which IMHO is very bad. Would be worth something if you develop a site on it.
The bad thing also about that domain is the word "photoshop" because Adobe sometimes send letters to domain owners saying they are using Adobe trademarks: "1. You may not incorporate or include Adobe trademarks in your company name, product name, domain name, or in the name of your service." http://www.adobe.com/misc/trade.html
