Very high res rendering
-
Thank you all for your responses. I've been researching a bit further, and you're all right - perhaps 300 DPI is too high! But I think it will need to be 150 DPI, as it is important the images are kept sharp because although you get full effect from a distance, people will still be able to view them closely. So, it'll still need to be 3 times larger than podium can offer. I am using photoshop as my photo editor. So, I guess I should try to work out thomthoms camera tools and try exporting in segments and see how I get on from there!

If the image is not placed on the ground i am curious about the destination of it for a such resolution!
Who knows, dear pilou, who knows.
Maybe the walls of:
a) a sheik's residence
b) an art gallery
c) some expensive hotel or club
d) etc...Sometimes we have silly wishes but sometimes we get some extraordinary comission.
skylabridges,
I hope you'll step by here to tell us your solution once you finish your work.
It may widen knowledge of some of us.
It's not everyday that someone prints a high-res 5m-sq art-work.After all - if you don't find a printer which can print it all at once - maybe you don't need an image editor to merge partial high-res images.

Yes, you're right Aureus - it's for an art gallery, and it will be printed in pieces, so perhaps I don't need to join it up after. What I think I need to do is find a plugin which can keep the image as a still object, other than to move to different areas of it, but all on the same plane, because as soon as I use the hand to move around, it changes the angles. I hope what I've written makes sense, and does anyone know if this plugin exists?!
Anyway, I'll keep this thread updated on my quest for large scale printing!

Thom thom camera tools, as I said. Just move the shift x and shift y around and you'll get what you need.
It's a pity we can't render from within Layout, as you could easily do the splitting there
EDIT : If you can't do the maths, just design a grid in your full perspective scene, with the amount of columns and rows you'd need to split the image.
Then you can have a visual reference for shift Y and Shift X

The image below was printed out for a Gallery. It is mounted on wall and is viewed standing.
There were 4 pieces mounted on a single board. The final resolution was 15,360 X 8640 at 300dpi. The poster size was 80" X 42". It was hung only 12" off the ground. Of course you needed to be 7 feet tall to look at the detail at the top so as everyone has pointed out the viewing position is the most important consideration.The poster is just fun to look at because of the detail. 300 dpi was about right. I worked my way down from approx. 500dpi printing test strips for the client. The beach guys in the small image are inside that little red dot....lol.

Thank you so much JQL - I'm going to try this now. I'll let you know how I get on! Roland Joseph - how did you manage to render at such a high resolution for such a large image? Did you also cut yours into pieces?!

There were 4 renderings. My rendering software is capable of 7680 X 4320 and actually I have given you the wrong numbers sorry, I was using my memory which is getting pretty bad apparenty ........ Here it is exactly:We took the largest render we could achieve 7680 X 4320 and then began printing test strips to see how far we could enlarge and print it so that the detail was clear while standing and viewing. The images were lining a hallway that people traveled through and so we had a height limit of 9 feet.
The original image specs are these:
When enlarged from 7.557 inches at 1016 dpi to 40 inches the image was then 40,650 X 22866
That's pretty unmanageable..lol. I tried 500 dpi still to big, then 300 dpi which worked out great for the detail at the viewing position.At 300 dpi the pixel count was reduced to as you see it below...12000X6750
All of the final prints were 4 print collages except for two. The images that were sewn together were set up by hand basically...by adjusting the camera lens length and repositioning to get as orthogonal as possible over the section. That was not easy (shadows drove me nuts) Camera Tools might help but if you are creating one image it can be done within the renderer by-eye with some struggle.
So the final mounted images were exactly 24000 X 13500 @300dpi. 80 inches X 45 inches.

hey...no trouble...your welcome....

haha, sorry Roland Joseph - thank you!
-
I wonder what was the solution after all.
-
Sorry this has taken so long to report back. In short the answer was that I could only render reliably at 9999 x 9999 pix. I couldn't get to grips with splitting the image using camera tools. I ended up enlarging the renders in perfect resize and got pretty good results from this.
