In reply to Nina. An Internet search should be able to answer those questions. This isn't a support forum.

Thanks for your response. Is there a way to remove alpha channel from exr file? If not how to convert a png file to jpg using python and imageio?

In reply to Nina. It may work, but it's certainly not bandwidth or space efficient (GIFs have poor compression). At the very least, use a PNG. Removing the alpha channel and using a JPEG, is still much better.

In reply to Nina. You need to remove the alpha channel from your EXR file.

Hi,

I tried to store the tone mapped image into gif format instead jpg format (because gif format support transparent) and I get good results.

According to you.Is true what i did? thanks for your response
