EOS R5 choice of shooting in CLog or in a normal picture style under indoor or nighttime conditions

[juiH]

hi,

happy new year in advance

i was wondering whether it is more advisable to shoot in Clog or in a normal picture style with my EOS R5 ( or EOS R ) in a mixed lighting situation of artificial lights indoors and artificial lights outdoors

i understand that log is usually used when sufficient light is available otherwise the images may become noisy however i wonder what the specific advice is in relation to these two particular EOS mirrorless bodies

i usually shoot at iso 800 and almost always use an X-Rite ColorChecker Video colour chart to correct my images

i currently have the RF 15-35mm f2.8L IS U and the RF 24-70mm f2.8L IS U which i use for both photography and video which i am aware only open up to f2.8 however i do have EF primes such as the EF 24mm f1.4L, the EF 35mm f1.4Lii, the EF 85mm f1.4L IS and both the Zeiss Milvus f.14/50mm and EF 50mm f1.2L which i could use with an adaptor

thank you

C-LOG has greater dynamic range and that means you will possibly see more noise in the darker shadows that it can capture. Using a Picture Style has less dynamic range and this means that often the shadows a simply black rather than show the noise. 

So this means that the question is more, do you need the dynamic range of C-LOG and the increased grading flexibility or the simplicity of a movie shot using one of the Picture Styles?

i come from a background of DSLR's and videocameras and a Sony Cinema Camera

we were advised to shoot the particular Cinema Camera, an PXW FS-5 in a picture profile rather than in slog ( in low light conditions ) because that particular cinema camera had a sensor that was not particularly sensitive to light but the Canon EOS R5 and R seem to do Okay at iso 800 and maybe iso 1000.

but given that i would colour grade the footage anyway even if it were shot in a normal ( standard ) picture style, i was wondering whether i would get better results in a normal picture style as log usually has a gamma curve that requires more light in order to hold the highlights which may be absent in darker, indoor or artificial lighting conditions

juiH,

Here is an article you might find helpful.

If you shoot Log on the Canon EOS R5, you should shoot C-Log3. Here's why.

I don't begin to understand everything he is talking about, but you might find it helpful.
