Macro Pi – Focus Stacking using Raspberry Pi

Here’s another in the series of articles of photographic uses for the Raspberry Pi SBC (Single Board Computer). This time, it’s re-purposing an old flatbed scanner as a macro rail for focus stacking images in macro photography.

Camera Pi – DSLR Camera with Embedded Computer

I’ve had the idea of embedding a computer  DSLR camera for a couple of years now, but for whatever reason I never got around to implementing it, mostly due to the cost of small single board computers. Until now, that is. With the release of the Raspberry Pi, embedded computing has all of a sudden become much more affordable. At €35 for the computer, it’s far cheaper than any of it’s rivals.

So what I’ve done is take an old (broken) battery grip that I had lying around (for my Canon 5D Mark II), and made a few modifications to it so I could fit the Raspberry Pi SBC (Single Board Computer) into it.

Workflow Tip – Fast cards & Fast readers

Here’s something that might be of interest, and will help speed up some parts of your workflow.

Get a faster memory card, and the means to get the images onto your PC as quick as possible.
I recently ordered a couple of 600x Duracell 8Gb Compact flash cards from 7DayShop.com….
They give a read speed of 90MB/sec. and are only £20.99 for 8Gigs. That’s great value. Continue reading »

DIY Intervalometer for Time-lapse videos

(See edit below regarding DSLRBot. A slightly more expensive solution, but quite a bit better…)

Recently I was awe-struck by a Time-lapse video by Terje Sorgjerd I saw which was shot around El Teide on Gran Canaria early in 2011. Looking around on the internet, I saw various solutions for time-lapse, including some very fancy rigs for moving the camera as it’s shooting the images. What I needed was something that could trigger my dSLR camera to take an image at regular intervals over a few minutes up to a few hours. The camera already has a port for a remote switch, so I needed some way to trigger that at regular intervals. There are solutions available as cheap as €50 on e-bay, so I wanted to see if I could do it a lot cheaper than that. Continue reading »

DIY Double Flash Clamp (under €5)

I was browsing around Woodies DIY today, and spotted the following clamps for sale in the bargain basement bin at €2.99 each. The spring was strong, and the plastic seemed like the good quality, hard wearing type. So I purchased a couple with some DIY strobist work in mind…

I noticed that the plastic jaws did not have a lot of grip:

so I super-glued some bits of bicycle inner tube to them:

Next, onto the real reason for the purchase, the double flash mount. This consisted of a simple tube bolted onto one of the handles of the clamp.

The copper tube has a bit of timber jammed into it so the tube would not collapse when brolly/strobe holders are screwed onto it. A simple drill hole in the clamp handle, and a drill hole throuhg the copper pipe, with a 30mm bolt and wingnut to hold them together. All done. The Result:

They’re probably not as strong as the Manfrotto clamps, and would struggle to hold a flash out horizontally, but the have no problem holding two strobes in the position of the image above, and would have no problem hanging from something. Not bad for under a fiver….
