I would like to render pictures to disk so that I can have a poster made of the image. I am lookig to make a few 24x36 posters.... Do I need to render to a user-defined size and make it inches (36" x 24") and set DPI to 2400 which takes days to render.... thanks

You can try to extrapolate your render from 24"x36" in 72dpi to 24"x36" in 300dpi in a 2D graphic prog (use bicubic extrapolation), or use special fractal progs to do that. But I have no experience on printing artwork, just saw that in Vue forum some month ago. ;=) Yves

Hi klehner, you don't have to render it with a resolution of 2500 dpi!If you want to make a paperprint of it 240-300 dpi (dots per inch)are enough.The size of your images can be defined in the user -defined settings.I don`t know if you're referring to inches or centimeters now,but to get out how many pixels you need you can use programms like photoshop which show you the relations between size and resolution (simply create a new file ).In every case: first define the resolution and then the size. cheers rollmops :-)

Printers usually wants an image that have at least 3000 pixels on the longest axis in size, 300 dpi and CMYK. But that depends a lot on the printing method. And they don't love images resized in photoshop, or any other software. Just learnt that in school :) If you got a great image, days in rendering, is a must :)

Most printers who deal in Poster size prints will settle for 150dpi, which would mean that for a print of 24"x36" the rendered dimensions would have to be 3600x5400. Also, try to use the TIFF file format in (as Alekssander has already mentioned) CMYK. The best thing to do, if you are not sure, is to contact the print shop you are going to use and ask them what they would prefer to work with...:o) Cheers

I would suggest that before you make the big print, print a 8x10 or something first to get an idea of how the render will print.

maybe one additional information. CMYK is ok, 240-300dpi too. And 1 cm in 300 dpi refers to 118 pixels. Test it out in Photoshop if you want to proof it (define an image of 1 cm or 1 inch wich 300 dpi resolution and look under image size how many pixels you do have). And then go back to Vue and define the amount of pixels you need. The rest is waiting! One thing to Alekssander. If you scale an image up in Photoshop you "add information" in form of additional pixels. And this is only possible because how can any program know which sort of pixel information has to be added? Simple rule: scale down: yes (you give up information which is already in the image), scale up: NO! lol, Walther

Wabe : not exactly. Scale up = new informations of course, but you can interpolate with bicubic in classical graph applications, or use fractal programs which seems very powerful (follow the link posted by guitta for further infos). I tried yesterday classic bicubic interpolations on a pic, it worked fine. Fractals progs are shareware, you can download them and test them , for example : http://www.lizardtech.com/ Now : why bicubic and not bilinear ???? Because bicubic is for scaling up, bilinear is for scaling down . It's not so easy to scale down too :=) Before you have 2 pixels, after there is only, lets say 1 pixel. How to proceed ??? ==> bilinear interpolation. I saw that on the web. ;=) Yves

right Yves... BUT it will always be an interpolation! There are cases where it works well (i.g. soft images with a lot of smooth degrades etc) and others where it is not tolerable. AND nothing is better than a good original! That's like in life :-)) ! Thanks as well for the links, i will check these. Walther

Even during rendering there is a difference between "soft images" and "hard gradients images". Recently I was working on a picture with high contrast, and Vue was not able to antialias in the zone of very strong contrasts (in a very good rendering mode). I think there is a problem to print a poster you are obliged to render in a very high quality mode : you can't spend days and days to render very big sizes. In that case, interpolation must be considered, I suppose. Since it may be impossible to use lesser quality for the render. When a high quality is not an obligation, there is no problem to render very big sizes. For the "fractal" programs I'm very curious to see their efficiency ;=) Yves

Maybe it would be best to talk to a printer first. I have the experience, that most does want the master 1:10 (10 times smaller than the poster). And the software for printing does the rest. I do have some pretty good experiences with even A1 (=594x840 mm) and an image that is originally only A4 (300 dpi) big. Digitally printed. But Yves your right - i'm curious too to see the efficiency of a "fractal" program. :-) Walther

Maybe I will try "fractals" shareware in a few days also ;=) Yves
