I was baffled by a situation today in which my subject was a vertical close-up o f a dense bank of reeds. The bank of reeds began about a foot from the lens and extended away from the lens to about 15 feet. My intention was to create a str ong, powerful feeling yet was unable to do this because of inadequate DOF. No m atter what aperture or movements I used I could not retain sharpness front to ba ck. I've never encountered a DOF problem as severe as this. My question is wha t could I have done to correct this? (I was using a 4x5 monorail with all movem ents available and a 135mm WF Ektar. I would have liked to use a longer lens but I neglected to bring my other lenses with me)
