Ok so...... the only supplier of filter for digital backs sells a filter made by Hoya... the original filers are made by Schott . Although they are equivalent, they have a very small difference. This means that you must create a custom white balance.
I shoot a colorchecker in the studio but for landscapes 5500 and adjust by eye . Anyone do this custom white balance in camera. Is it done once and thats it then the lcd will display all at a perceived 5500?
