Hello friends,

here two old examples but generated with my new quad gtx580 workstation.

These are only tests. The light comes from the sun passing one piece of glass and curtains, no mesh lights.

The image isn't photoretouched except for a slight denoise filter (Nik define)

3507x2336, ready for print.

History:
the scene was modeled by me with Rhino and Max (many objects comes from Evermotion) rendered with Vray. In few minutes I changed some materials within Octane.

noise is the difference.
tons of noise in the first one, a bit less but still a lot on the second.

yes...but think of...

If you print the first one you will not have any noise because the prints are 300dpi or more.

We evaluate our renderings watching a 72 dpi (sometime more) lcd matrix.

I saw many print ready renderings generated by iRay that had a lot of noise. The printed brochure hadn't any noise.

try throw that out on a A0 1 meter 20cm wide and 80 cm tall or so.
brochure is tiny canvas.

>try throw that out on a A0 1 meter 20cm wide and 80 cm tall or so.
and ask 10 people. 9 didn't notice anything.

lies

If a client of mine starts to want A0 300dpi renderings he has to pay 750€ for each image. Next day I'll buy a Tyan barebone with 8 Teslas.

None prints A0 at 300dpi except for cad drawings or illustrations. No photographer own this camera:

If you (client) want 50Mpx shots means that you have a lot of money...

I rendered out a 75MP shot three days ago for a client....large 3x4m aerial rendering for a residential area.

But what I want to ask: How many samples do you get with 4x GTX580 and what power-supply do you use? I consider buying another 580 because with my 800Watts PSU nothing more cant be used.


For the pictures: Clearly the greenish noise. And I think some clients will notice..I have lots of clients which doesnt notice too but hang on other small details which they want to change seometimes.

When the picture is mindblowing a little bit of noise doesn't matter!

I am curious about you guys doing these commercial jobs in Germany that seem to pay so well.
Where I live while people might be impressed with a photo realistic render they won't pay for them or very few of them so that it is hard to justify a lot of time setting up detailed scenes with best textures.
They agree the results are nice but it seems like more technology and artist skill than they are prepared to make use of on a regular basis or unless the project is substantial.
It must be a well established part of the architecture and interiors scene there to present to the client with nice renders so there is a decent budget for it built in to the overall cost.
I wonder what does a typical job consist of? the number of renders , size etc...
Not asking you to give away secrets, just curious...
