Okay heres my situation. I tried something out of my realm of photography comfort yesterday afternoon/evening. Some still life work. I used only natural lighting and some burlap (bought 2 yards at the fabric store for $4) and some exotic flowers from the local central market. The flowers (forgot the name) are a deep maroon/reddish color with green stems. I shot them last night not using any filters at all with my Cambo 4x5 Monorail, 135mm lens, tripod, some lawn chairs for elevation, the universal lighting system (aka the Sun), and some Ultrafine 125 4x5 film. The exposures were about 1/10 - 1/20th of a second at around f22/32 and the negatives developed in PMK pyro for 11 mins. it was my first attempt at still life, composed photography really but Im pretty pleased with the results (these are just scans from my flatbed that are attached - the shot with the shadows from the tree will get reshot - I was out of sunlight and couldnt find a large enough piece of lit decking, altho I find it kind of interesting nonetheless) what Im interested in is whether a red filter or a green filter would serve me better to accent the tonal difference between the deep red flower and the green stem but still leave me the ability to retain detail in my shadow areas. I hope Im posting this in the correct forum. if not please anyone move it to the correct forum. thanks heres the shots.
