Mon Jun 21, 2010 Description
Trying for a photo like the garden magazines; with deep depth of field (high f/stop#) and focused throughout. Still have to work on it. Either the focus is in the foreground, midground, or background. Not sure how to remedy that. Step back further, maybe? Any suggestions much appreciated.

Mon Jun 21, 2010 11:02am Heidi, this is a gorgeous composition of colors, and you have perfect placement of the pink rose. Can you tell us what f/stop you used, and which item you focused on? In general, to get crisp DOF throughout an entire flower photo, you can a) Put the camera on a tripod and use a really small aperture, like f/14 or smaller. You'll need the tripod because this will give you a very long shutter speed, and if you try to hand-hold the camera you'll ruin the crispness with hand-shake-blur. b) Focus on a main subject about 1/3 of the way into the picture. c) Go "old style" and use a DOF/hyperfocal distance chart to tell you how to manually set the camera to achieve the DOF you want. This was much easier on older cameras where lenses were marked to let you do this, but it's still possible if you look up charts for your equipment on the web. Here's a segment I cut from Wikipedia and the corresponding website, but you can look up "hyperfocal distance" on Google to get tons of articles on this technique: "Hyperfocal distance The hyperfocal distance is the nearest focus distance at which the DOF extends to infinity; focusing the camera at the hyperfocal distance results in the largest possible depth of field for a given f-number (Ray 2000, 55). Focusing beyond the hyperfocal distance does not increase the far DOF (which already extends to infinity), but it does decrease the DOF in front of the subject, decreasing the total DOF. Some photographers consider this wasting DOF; however, see Object field methods below for a rationale for doing so. If the lens includes a DOF scale, the hyperfocal distance can be set by aligning the infinity mark on the distance scale with the mark on the DOF scale corresponding to the f-number to which the lens is set. For example, with the 35 mm lens shown above set to f/11, aligning the infinity mark with the ‘11’ to the left of the index mark on the DOF scale would set the focus to the hyperfocal distance. Focusing on the hyperfocal distance is a special case of zone focusing in which the far limit of DOF is at infinity." [ link ] |

Mon Jun 21, 2010 11:08am Here's a comment from a guy named Tony Sweet: "First off, hyper-focal is a function of short or wide-angle lenses, practically from 20mm to 35mm (approx.). A quick method that many professionals use, since we seldom have time in quickly fading natural light to consult charts, is to focus 1/3 into the film plane at f/22. This does NOT mean 1/3 into the scene. It means 1/3 from the bottom of the picture space (in the finder). Focusing at that point, at f/22, is where you'll achieve your maximum sharpness. Using charts for more exacting measurements for critical sharpness is great for controlled light situations where one has the luxury of time, e.g. studio product photography.

Mon Jun 21, 2010 11:28am Oh my gosh! Thank you Jennifer. I'm going to print all this information and study it and check out the links. I'm wasn't previously familiar with the term hyperfocal; learning so much here!! I shot this 3 times, each time with the focus on a different area, this photo came the closest to focusing everything. I did use a tripod and the settings of ISO 200, f/22 Aperture priority, camera selected 1/2 sec. shutterspeed at 50 mm. (ha! surprising myself that I understand what all that means!) Thanks again. I should pm you to make sure you get this - if I can work out how. Heidi |
