It’s just seed cone I picked up walking the dog but it became an exercise in creativity and problem solving.
To start with I just wanted a clean simple image with limited sharpness, I used an A4 sketchpad as a background and an improvised light source using a big window with a diffuser blind plus an iPhone box that was laying around as a reflector to fill the shadows. My 30 year old Calcuflash incident meter read f4 at 1/60, 400 ISO so I went with that. It’s not too shabby.
All up that was ten minutes effort but then I reworked the setup to get a sharper image. I could have gone with a longer exposure and smaller aperture but did not want to dig the tripod out so instead I went for flash. Using a ring flash diffuser I was able to use f11 at 1/160 sec, 400 ISO to get this;
The sharpness is there but working so closely (within a hand width of the subject) the light is not getting to the top of the subject and a lot of detail is getting lost. The paper is also over exposed in the top left corner.
The ring flash diffuser is a recent eBay purchase best described as a cross between a donut, a folding soft-box light modifier and a small drum. It cost somewhere between 20-30 dollars and for that you get a small soft-box that is really portable.
Solving this required a simple compromise using both the daylight and flash. Here is the result using f11 1/125 sec, 400 ISO. I also got a little further back to allow the ring flash to do it’s job better. The result is sharper and more evenly exposed. The only catch is the colour balance, which will always be an issue as the colour temp of daylight changes through the day.
Finally, for completeness I got the tripod out of hiding and did this at f20 1/4 sec, 400 ISO
Here is the set used.
