I'm going to Sedona for a week at the end of march. I will be shooting 4x5 tmax 400. I usually use an orange filter to help darken the sky a bit. But I'm wandering if that would cause the redrock to be become a bit washed out if it is being hit with strong sunlight. So I was considering using a green filter instead. I know the effect on the sky would not be as great as the orange but would help a bit. I also know the best way to find out is to do some tests but since this is a visit I'm not going to be able to do that in advance. So I'm asking any B&W photographers from the area what they would recommend. Thanks.
