Hi, Was just wondering what the figures meant on a depth of field table? For example, when looking at Schneiders depth of field table on their website, on the 8 x 10 format at a focus distance of 10 feet, shooting at 5.6, they give the near measurement as
9.63 (ft) and the far measurement as 10.28 (ft). Just wondering what they mean? By looking at these tables, I also came to the conclusion that by shooting at f2.8 on a 150mm lens on the 5 x 4 format, I would be achieving the same drop in focus as the aforementioned on 8 x 10. Basically I am looking to shoot full body portraits, wide open at 2.8, to get a shallow drop of depth, that would basically emulate this... From the sample images I am going off, the photographer has the image sharp from their eyes to their ears and then the image (background) falls off sharply.. Does the distance between the near and far measurements on a depth of field table, mean I should have sharpness from those distances? As mentioned before, I am looking to get both eyes and ears sharp... Or is the best way just to stop down? With my earlier tests shooting this wide open, I had trouble getting the person sharp. Also, was just wondering what an acceptable shutter speed (slowest) is to be using when using a field camera on a tripod?
Ok, thanks so much, any info and all of your thoughts would be greatly appreciated!!
Best Regards Josh
