I agree with with JamesD, (have you bought a new enlarger.etc.yet?)
Photo's taken during the devils hours (8:30am-6pm) are going to be flat and lifeless.
The only exception I've found is when you are taking deliberately hard, harsh painful pictures of very old, very thin, men with cruel and grizzled faces and piercing eyes close up. Then you can sometimes get away with the picture, if you get under shade and use the hard reflected light to make the picture even harsher. But how often does that situation come up....really?:er:
Also, if you are under a deep canopy in the woods, the occasional shaft of light can make for a compelling picture, if you are using film which has a naturally low contrast and wide exposure latitude, like tri-x.
You
might be able to do the same with digital...but I have not seen it done. Digi-B&W is just too muddy to manage the effect most of the time.
So...back to the light.
Lotsa' people are concerned with camera, lens, developer, etc, but the basic element...the light, is most important.
Try shooting during the magic hour.
It happens twice a day, from just before sunrise to an hour after, from an hour before sunrise to about ten-fifteen minutes after.
P.S. I don't shoot digital, but I've been around enough pixelographers to know that white balance is important, and the preset WB on factory camera's is very seldom perfect and sometimes terrible. Also, I've been told it goes out of whack over time and needs to be reset regularly.
