Many years ago as a young man I shot a lot of film. I had my own darkroom (B&W) and loved the smell of dektol...lol. Shot mostly cop stuff... crime scenes, car wrecks plane crashes etc. I understand the mechanics of photography. Shutter speed, f stop, film ISO, focal length, how to figure flash range, long exposures, all that stuff. Then along came kids, job and life. 25 years later I would like to get back into it. I'm looking for a camera that will do everything (and more) that my old SLR would do, such as change the iso, bulb setting for long exposures, adjust f stop and shutter speed manually, control depth of field etc. I DON'T HAVE A CLUE WHERE TO START! Suggestions?
