A bright sunny day and shinny glass greenhouses. Everything all at once to make a photo impossible.
If I was shooting film, 35mm days, no way would I even bother. But hey, it’s digital so the worst that can happen is I delete everything.
My solution was to ‘bracket’ the photo. Shoot one at the proper exposure, one a stop higher, another a stop lower. Basically a good one, then over exposed, and under exposed. An old trick to cover your bases.
The newer solution is to use software (Lightroom for me) and merge all three images into a single photo with all the ranges of color and exposure (HDR). In this case it worked and I can see through the glass.
At this point color tones and highlights can be processed to make any number of changes.
