Hey!
I ain't Ansel but technically these are not that great.
I guess this have to do more with the size than other things and maybe there is more to it when viewing it in person.
But of course you could make large mural print from a better 4X5 to 8X10 LF also.

Well, still I have to give it to the guys for going through all of trouble.

Take care,
Buddy
