Can Nerfstudio train and render HDR images (values above 1)?

[vincepapaix]

Hi

it will be great if NerfStudio allows other files type like EXR and especially if it can handle values above 1 (HDR images).

Currently, it seems like even if we train images that have a high dynamic range (values above 1), both the training and rendering process will output a clamped images (between 0 and 1)

Preserving the high dynamic range can be a nice improvement for higher fidelity nerf output.

thanks

+1 for EXR support, will be a big quality improvement for post processing filter/tonemapping.
