Well - first real prints I made years ago in bw was sized in 1.00m x 1.40m (135 film)
with 120 format it looks much much better to me.
With full optical workflow it is a decision of your enlarger lens if you can get real fine art prints.
The best enlarger lenses are most expensive - but you can also reach the last 12% remaining quality wich were absolute reachable. The general lost of resolution is caused from the optical system of enlargers.
But we know no enlargements without enlarger lenses in the past. So it was like best quality we can get on a first view from our enargements.
Cause we can't imagine what a film theoritical may show without physically restrictions.
With digital workflow and laser prints - there are complete new ways possible.
But physically restrictions have not changed.
So it becomes the task to the scanner equipment to avoid a lost of quality.
But with 8x10 enlargements (hope not to missunderstood you so we are not talking about sheed films) .....with such enlargements it doesn't matter at all.
It becomes an issue of interest if you need the max. quality in max. size of several diferent film formats.
Then the scanner system (flat bed/ film scanner / drumscan / multiscan) is in the same resposibility to allowe max. quality
as the enlarger lens from typical analogue enlarger system.
Because (I hope so) the resolution from the laser print system is above the losses
of scan and above the losses of any optical enlarger system.A typical machine to reach fabulous print quality is this here :
...the d-lab 2 plus from Agfa.
It reaches 400dpi print resolution with color deep of 12bit.
But the including scanner unit isn't the absolute best I must state.
If you want to have a little more of all you should make your scan seperately with this scanner :
...its the imacon flextide 848 one of the best scanning machines ever built
The optical resolution is 8000dpi with 16bit. You also may have the possibility to make multi-shot scans to spread the resolution a bit more. (so if your software is able to handle the data of 400MB Tiff / frame x the multisssion rate.)
If you want big enlargements without visible grain - you may have no alternate to highest standards from my point of view.
Exeption : Simple use of 8x10 films with
8 x 10 optical enlarger and Zeiss /Rodenstock lenses.
That is indeed unreachable in all issues of max. quality to big sized enlargements.
If we are talking about 8x10 enlargements - I have a next example.
My son made a nice shot on landscape with a cheap film c41 ISO 200.
A simple 8x10 enlargement from a drugstore has made him happy.
And thats the issue from format to me.
Notice : Poket110 was't to bad on very smal prints.2 MP digital equipment make also sence in same format on a sreen.
But big stuff isn't so easy to handle - I am real glad about - because grandma smith
is never able to reach it with her modernst equipment ....
