I use a CT straw 1/4 gel over my flash for indoors at reception in conjuntion with a one stop ND gel so i can shoot at f4 and use power settings on my flash based on f5.6. the reason i shoot at f4 is so the background is not as dark. I always have a 1/2 stop diffusion over the flash. Im getting brighter backgrounds, especially when i use asa800 film (npz), but my subjects dont look so hot. i shoot at 1/40 or 1/50 second. just wondering if maybe the slow shutter is giving me not so sharp shots? it is frustrating. i am trying hard to improve my shots, but sometimes the background is so incredibly dark that it doesnt really improve the look to go to all this trouble. Is the warming filter a problem? I am trying to warm things up a tad, but it seems that maybe it is negatively effecting my images. any suggestions? that warming filter is a must for sunset shots, the warm background needs a warm flash. even with the 1/4 CT straw gel, i want more warmth than that. would 2 layers of 1/4 ct straw give me more warmth, or do i need a 1/2 gel? just trying to improve things, ready to go back to doing nothing! I get to a reception with 800 film and i get a pitch black mood lighting. sometimes you cant win! comments pls, i know others contemplate these things. thanks!
