Okay, I have a dRebel, 6.3 mexapixels.

I just ordered a Epson 2200 printer... 13x19".

What is a good way to enlarge my pics to that size? I have been outputting the raws at 300dpi, which is about an 8x10, then enlarging the picture in 110% percent increments until I get it the size I want.

I tried GenuineFractals and cold tell NO difference between that and CS.

What is the "prosumer" limit that a 6.3 megapixel image can be enlarged? my friend has the 2200, and his 13x19's look great... so what is the consensus on this?
