Ok great, looks like I'm signing up for the sharpening class then  

Just double checking. It is possible for the reproduction to be printed again on canvas and look as clear as the original at the same approx A0 size? 

Ok thanks, I'll try again and let you know. So you think it's the lighting that is the issue? 

I've done a few different versions, including, constant lighting set high at a 45 degree angle and me shooting behind the lights, also tried with lights whine me, have tried with the lights facing straight up with the idea it might create a better disbursement of light but it just created more shadows and enhanced the raised bits on the canvas making it appear extremely dotty, I also read that a polarising filter on the lens could help; it really didn't. The best so far has been using the daylight first thing in the morning with it being overcast. 

Yes, and that it no longer is a good representation of the original. I feel like it looses it clarity. Also printed to A3 still looks great, but any larger it starts to look awful. 

Yes that's right

Here you go 

Also using a tripod and delayed timer when shooting

Hi, I have a piece of art work; landscape on canvas that I have photographed and the artist wants it blown up to print approx A0 size for reproduction prints. I have photographed it and all appears sharp and in focus but when I either zoom in to 100% or get the printer to print a sample spot it looks really noisy and not so sharp. I have resampled when enlarging. What am I not doing or doing incorrectly? 

Thanks
