Hi keep the ISO as low as possible i.e. 100 no more than 400 at the death, me personally use custom white balance but if you are shooting RAW it doesn’t really matter…
Me and my dyslexia it should say matter ha ha…
The white balance setting doesn’t affect the image data in the RAW file, but the setting is recorded in the meta data in the file, so you can still use it to process the RAW image if you like.
