So, as a followup to my previous post, I'm going to be rendering a large
image to be displayed on a 6 meter tall by 3.5 meter wide wall. Obviously
this is massive. What sort of DPI should I plan for here? At 72dpi the image
will be 17,000 pixels tall which seems crazy. But then, maybe it *should* be
that large.

The slowest part of the image goes at about 800 PPS so I can afford to
render at extremely high resolutions if necessary.

Are you expecting people to sometimes walk up and examine the poster at 
close hand or just look at it from a distance? If it is only to be viewed 
from a distance, then a DPI of 100 or even just 50 is probably acceptable. 
Normally the guiding principle is that posters should have a DPI of at least 
150, but what you're making is definitely not a "mere" poster.

Also, does your image have detail that requires a high DPI to show it off 
properly? If the image is photorealistic, and the image has some "shortcuts" 
where detail have not been created in an extreme level, then a higher DPI 
might just reveal this fact even more and make the image seem more crude. On 
the other hand, images where simple shapes and textures are an integral part 
of the style will often look fine when blown up to a high DPI, though it 
still might not be necessary.

Naturally, if you're using focal blur, or have any other valid reason that 
the image would naturally be slightly blurred, then a extreme resolution 
seem unnecessary.

That's a prety large image. 6m by 3.5m is murale scale, and you don't normaly 
expect peoples take a look at it up close to such a piece.
I'would try something around 20 to 50 ppi. Take a look a bilboards, the pdi used 
may be as low as 4 to 8 pdi! At about 1m or less, it looks very pixelated, but 
take one or two steps back and it looks all nice and smooth.

One thing you may do and get away with: make the botton 2m part at around 50 to 
80 dpi, and the part above that at only 20 to 50 dpi, maybe going down to 5 to 
20 dpi for the uper 2m.
