Lots of plusses and minuses with showing framed work. If it isn't good quality it degrades the image and its value. If it is good quality the total price is higher and that may turn folks off. But the biggest problem is that you are making the buyer's decision regarding color of matte and frame and they may not tell you that your choice sucks but simply walk away. I happen to like the framed examples shown here. But I also happen to know that black frames and white mats may not be the best possible choices for the general art show type of buyer. Here's why I say that--granting that my experience may differ from others here. My best selling gallery sells about 70% painting prints, and 30% photography prints. They cater to weekend crowds in their venue of 10,000-30,000 per day. They mat and frame about 100 pieces per week. Most are double, triple, and quadruple mats with non-wood frames. All mats and frames are chosen to work in nearly any decor and color scheme. 98% of their sales are impulse sales with 2% opting for custom framing not on display. They never use black frames with plain white mats. Their experience has been that each print can be enhanced with the proper matting and framing yet still fit most decorating situations. The black and white treatment just doesn't fit with the majority of their customers.
