How do I export a High Resolution image from Blender? Say an 11x17 300 dpi image that I could bring into Photoshop and manipulate?
This should be pretty straightforward, but for the life of me, I cannot figure the settings to do that.
Thank you,
Jim
Dpi (or more correctly ppi) is easily calculated - create a 11*17 (cm? inch?) file at 300ppi in Photoshop, check the resolution, and use that in Blender’s render settings.
For inches that would be 3300 x 5100 pixels.
After rendering, open the image in Photoshop, choose Image–> Image Size, de-activate “Resample Image”, and change the ppi resolution to 300. Done.
I feel you do not really understand the concepts behind dpi/ppi and actual pixel resolution. Read up on this subject on: http://photo.net/learn/resize/
Thanks hvanderwegen!
That makes sense. Essentially Blender Exports by default as 72 ppi…and then you compensate for it.
I am trying to get a high resolution image of my model to a designer.
My next task:
Figuring out how to separate my Model from the background…
Right now I have a Blue Background (sort of a fake blue screen) that I was hoping to clip out…but an Alpha Channel Export is what I am looking to do.
CartoonCaveman: http://wiki.blender.org/index.php/Doc:Reference/Panels/Scene/Render/Renderit’s important you read all, but what you want is rgba and premul (dont forget to save the image in a format that supports alpha channel, ex. png)
Blender doesn’t export/save images at 72dpi, it just saves them at the pixel size/resolution that they are. Your display settings might be set at 72dpi, or 96, or 110, etc. That will be representative of how it looks on your particular monitor. When you open it in Photoshop and tell it, as stated above, to be a 300dpi image, (without resampling), then it essentially overrides the default setting of your display settings.
paulo _gomes: Thanks! That is exactly what I was looking for!!
Using the presets: premul and rgba…when I open it in Photoshop the Alpha Channel is there!
anitmatter289: I figured out how to do the re-sampling…but I like your idea of changing the output settings to output to 300 dpi/ppi right away…
Question: Where are those settings?
(I’ve been working with Adobe products for so long…)
Blender is an Amazing Program…my one complaint are the controls (tools etc…) aren’t as user-friendly as the adobe products, or maya’s toolbar etc…(but it’s open-source, so…hard to complain abut that too much!)
antimatter289 wasn’t referring to DPI in Blender, as there is no such paradigm in Blender. Blender is capable of outputting an image of almost any pixel dimensions required (memory dependant).
In Photoshop, open any image of any pixel dimensions.
Go to ‘Image > Image Size’. Uncheck ‘Resample Image’ and type in 300 in the dpi text input. Watch how the Document size changes in dimensions. This is just showing you that the physical print size is different, because you are telling it to print with more or less pixels per square inch of paper. The number of pixels doesn’t change, only the print density… per square inch.
