Large format images

[miguel martinez]

How can I generate large format images, like ´8 feet long by 8 feet wide.
thanks,

Try not to go over 50 DPI (4,800 x 4,800) or 75 DPI (7,200 x 7,200)

Make a 8" x 8", (small),  test image by rendering at 400 x 400 or 600 x 600 and check the print quality on your photo printer, (or 5" x 7" at similar resolutions), I think you'll find that one of these resolutions will work for the larger image.

You should be able to render these sizes if you have enough RAM.

Of, course, the other option is to render just 1/4 of the screen at a time, and stitch the images together.

Does anyone have any experience with this?

I have a 2400x1600 resolution with 100 pases and it is blurry when printed in large format. I will try to work on tiles.

thanks

How large did you print the 2400 x 1600 image?

8 feet by 8 feet. It does not define very well shadows. It is blurry in the edges.

for 8' x 8;, try 50 DPI (4,800 x 4,800) or 75 DPI (7,200 x 7,200)

I would expect 2400 pixels (just 25 pixels per inch on paper to be too low a resolution)

If you have enough RAM, 7,2000 x 7,200 should take about about 14 times longer per pass. But, especially for a test, you can render just 5 or 10 passes to see what the quality looks like and then add more passes later when you are sure what resolution you want to use.

I am going to try 4800 to see how it goes.

Thanks.
