Hi What is the best response filter to use to create images similar to what professional companies use like Pixar etc
Currently I use agfacolor futura 2 100CD but some one said only use linear but linear creates dark oversaturated image
Thanks

I use linear mostly too and do the post editing in Photoshop but also set the filter in the renderer itself for smaller projects or where I will need to do batch-processing later.

The kind of filter also depends. I just use the one which I think looks best for the specific scene. If one filter creates a darkish look on one image it may be the extra little kick of contrast in another.

i used to use linear but notice that every single scene setup has its own best. i dont care if it is false or not just use it for my taste. this subject will make me clear. my eyes on it.

Thank you all!
We do animation and try to have image quality closer to Pixar etc as far as color space.

I tried linear with gamma changed to 2.2 but everything looks bluish now. So now we use Agfacolor 2 Seems like it is closer to neutral. We just dont need any camera responses that make image greenish or bluish. We need more neutral image

Thanks. I thought if image is already was changed to greenish and then I use white balance it alters image even more. I'll give it a try

Although this is a very subjective and content-dependent answer, I find that Kodachrome_64CD is a great starting response that's mostly very neutral but has some niceness to it. Kodachrome_25 is similar but slightly warmer. Gamma at 2.0 for some punchiness.

A good starting point for Post Processing is Bloom at 2.0 and Glare at 0.2
Glare usually works best at 10% of Bloom, as to not be overwhelming.
A spectral intensity of about 0.2 will give the bloom some visual interest, and mess with the Spectral Shift (0.0-1.0) to see what you like best. When you get a good setup, empty your scene and save it as a blueprint/template that you load up whenever you go to start a new project, that way you don't have to mess with all the settings every time.

I noticed when using different kernels like DL and PT different response filters suit it the best.

I like the oldschool exposure so you can still mess around with the iso
