Originally posted by Na Horuk But I think there is a general rule, which has to do with diagonals. You need to be a certain number of diagonal lengths of the print away from it. If you do that, even a relatively low print resolution will look okay, and the photo will look generally like the artist intended. I forget the exact formula, but Im sure someone will mention it.
It is something like that I am looking for.
About resolution...there must be some limit there too. If you are too close, even if you still see details, you only see details in part of the picture, and miss out the whole picture. A bit like not seeing the forest for the trees...
