I need urgent help with setting up DPI settings at export.
I’m exporting still images using the StillRenderSetup widget found in MovieRender’s folder. The stills will be printed for a physical exhibition preferably with 300 dpi. I had a look at UE’s DPI scaling but I don’t think I’m following it correctly and I couldn’t find tutorials on it either.
I’m currently rendering an image with 96 dpi and 72 ppi (both of which should go up to 300) at 6K.
I’ve set up Temporal Sample Count at 64 under Anti-aliasing; and 6-8 tile counts under High Res.
Hi jinxewy
DPIs are relative to print size. We don´t render images with 72 or 96 dpi, we render images with pixels.
If we want to print an A4, we need 2490 x 3510 pixels.
8,3 in x 300 = 2490 pixels
11,7 in x 300 = 3510 pixels
If you cannot find a setting within Movie Render Queue, then you can edit the DPI later in the final image with almost any photo editor or drawing program to your required number.
Photoshop, Gimp, Krita (there its in the image scale menu, have checked it just now), IrfanView can do it too (this one should even be able to batch render a whole image serie).
DPI is only relevant for printer (maybe for scaling on different sized monitors too), as mentioned above, they don´t matter for rendering or pathtracing.
Editing the DPI will not have any influence in the pixel size of the image itself, or if f.e. Photoshop offer an option to resample or resize the image, don´t use that, just change the DPI number and that´s it.
Exactly.
By the way, dpi exif is some kind of “accursed legacy that haunts forever”
Changing exif dpi does not change image quality at all, but client insists on seeing 300 dpi on exif
To clarify dpi doesn’t change image Print quality, if I render at 300 dpi at A4 size there is no image quality gain? or do you mean I will have to render larger then print at A4?
