I was out taking a few closeup shots of flowers today using Polaroid 55 P/N film . My scale of reproduction was between 1:1 and 1:2 with a 90mm lens. Each time I adjusted focus by moving the front focusing knob the flower would either grow smaller or larger with little change in fine focus. I was able to get it in fa irly good focus, but it seemed a little soft. I tried f-stops as high as f45. I have a Wisner 4x5 PE. Since I'm new to large format cameras, I figure somethi ng is wrong with my technique. Is it common for closeup items to grow while foc using? In some respects this growth makes since because the lens itself is movi ng while the subject is relatively stationary. However, how does one achieve pe rfect focus without the subject growth? Is this possible? I guess my question boils down to, "What is the best focusing techique for closeup photography"? I know tilting the lens want help in this situation since the scene is mostly in t he vertical; hence, I'm left with f-stops as my primary means of controlling dep th. Any suggestions or comments would be greatly appreciated.
Thanks in advance,
...Wade...
