Pinhole day 2013

Here is my entry for this year’s Worldwide Pinhole Photography Day exhibition:

Pinhole day

Yesterday was Worldwide Pinhole Photography Day, I submitted a picture of some ferns:

The obligatory dandelion

Since I’m experimenting with wide spectrum photography, here are the obligatory pictures of dandelions. I don’t have a UV flash system setup yet, so I have been taking all my UV pictures in full sunlight. I usually take all my flower pictures around sunrise, but have been waiting until later in the day so that [...]

Visualizing a wider spectrum

Since I’ve been playing with the beyond visible photography, I’ve also been looking at ways to visualize more “colors” than we can see. In yesterday’s post, I simply split the pictures into separate grayscale images: near infrared (IR-A), red, green, blue, and near ultraviolet (black light, UV-A). For this to be more than a fun [...]

UV Photography: Early Images

I’ve been gathering equipment for a project involving ultraviolet photography for quite a while. I finally have enough equipment to shoot some test photos. I used several blooming crocus in full sunlight to test my beyond visible photography setup: The ultraviolet (UV-A) image likely has a large amount of infrared (IR-A) contamination, but I should [...]

Prairie Dock

I took some pictures of Silphium terebinthinaceum, also called prairie dock or prairie rosinweed. This is a fairly tall prairie plant, so I had to stand on a step ladder to take the pictures. Balancing on a ladder while trying to take critically sharp pictures of bees on flowers that are six to nine feet [...]

Which lens?

I’ve been playing around with different macro lenses. Can you guess which lens I used for which picture of a native compassplant (Silphium laciniatum)? In no particular order, the lenses used are: Nikon AF Micro Nikkor 105mm 1:2.8 D Nippon Kogaku (Nikon) El-Nikkor 80mm 1:5.6 Tokina AT-X Macro 90mm 1:2.5 All three photos were shot [...]

A new lens

It took a while to find one of these for a good price, but I now have an Nippon Kogaku (Nikon) El-Nikkor 80mm f/5.6 enlarger lens. It seems to work well as a macro lens when mounted on extension tubes using a M39→F-mount adaptor. Now I just need to find a 34.5×0.5mm→anything else adaptor and [...]

Check out the photography of Chris Kotsiopoulos. He has some impresive astrophotography on his website, and has been featured on APOD several times.

Nikkor 18-70 repair

Earlier this year, the AF-S Nikkor 18-70mm f/3.5-4.5G ED that I frequently use stopped zooming. Since this is known as an excellent lens, and the zoom was the only problem, I decided to attempt to fix it. Working on lenses is usually a hassle, so I was pleasantly surprised at how easy it was to [...]
