I am doing a portraiture project where I will take a number of images in "shady" outdoor environment. For this project, I am using 4x5 and 150 and 210mm lens on color films. I have used strobes in studio setting before but only with a Leica and dSLR so far. This thread talks about using monolights and 4x5 in studio setting: http://www.largeformatphotography.in...389-Monolights Anyone has advice on using monolights in outdoor setting as fill lights with 4x5? Thanks.
