Hello, given that your Skies wash out with both the 1A and UV Filtersm there are in my opinion 3 options open to you: - underexpose by 1/3rd to 1/2 stop (not for diapositiver film) - get a polariser (takes about 2 LV of light) - try the Skylight 1C filter (stronger than 1A, but not as strong as a polarizer) Also I dont recoomend stacking filters, for the following reasons: 1) With every glass surface betwen the object and the film, additional diffraction occurs, which costs obth light and definition 2) the stronger filter usually cancels out the weaker one.
