Iray+ Rendering: Static Image Resolution

Pioneer

Hello,

Even though I change the image output resolution to 300dpi, I get a 72dpi image when saving the static image. It does not save the dimensions either.

Why does this happen? How can I solve it?

Hi,

I think the maximum DPI you can achieve depends on your display screen (standard displays support 72 DPI normally).  Achieving a 300DPI might require a better graphics card.

Hi Kapil,
Thanks for your answer.
Anyhow, when saving a "High Quality Image", I can choose between 72DPI or 150DPI, if I select the latter, the image is saved with 150DPI. I don't understand why the Ray trace static image does not work that way...

It does not make sense to me to improve the render motor, that can achieve good-looking results, but can only be saved in poor resolution. Maybe @PattiLongwinter can help me?

Sorrry i am probably wrong....i can use SNAGIT to capture a 300DPI image...even when the ray traced studio outputs a 96 DPI image to me...

Over to rendering experts now.

MSV, This is what I got from our development team.

 

 

In the example below, I have a 254 mm by 254mm size with a DPI of 300.

You will see that the saved image’s dimension is 3000x3000 which is correct since 254mm is 10inches, so 10inches X 300DPI = 3000 pixels.

 

You need to change the units from Pixels to Inches or Millimeters and then size the image accordingly.

 

Hope this helps.

Thanks for your answer bevyboy.

The properties of the exported images are:

Should I understand that Ray trace is exporting a bigger image than it should be in low DPI, instead of having the proper size in mm but with a higher DPI?

 

Edit: Checking with Photoshop, I can ensure that the image is 41.67 x 41,67 inches. Then, I have to create a new Photoshop file in 300DPI and 10x10 inches and copy the image there, to create an image with the desired dimensions and resolution.

 

3000 pixels / 72 dpi = 41.67 inches

3000 pizels / 300 dpi = 10 inches = 254 mm <- Proper size and resolution

 

So, everytime I need a image in good resolution, I have to make this annoying step (that for sure is making me lose some quality, since it has to go through another processing step). Is there a way to solve this?
