The colour filters are usually labeled with the filter factor. For example Y2 is yellow with filter factor of 2. R7, red with filter factor of 7. Take the ISO of the film you are using, and divide it by the filter factor. So for example 400/2 is now 200, 400/7 approximately 50 ISO. You can also divide other parts of the exposure triangle like shutter speed and aperture, but I find it easiest to use ISO.
That image in the field of flowers is absolutely brilliant, congratulations 🥂
The Rolleicords are wonderful. I have the IV and its beautiful to use. Especially if serviced, they are so smooth and quick to use.
Nice camera, been looking for one of those myself. Love the photo of Corfe Castle framed by the gnarly tree.
Very nice :)
How do you calculate the compensation to the exposure when using filters?
For yellow open up 1 stop, for red two - looking to do video on use on filters during the summer. Thanks for watching. Andy
