Digital pinhole photography

Digital pinhole photography is something I've not tried my hand at for some time so I thought I would refresh my mind, go back over some old notes and give it a try with my current gear. I wanted to answer two questions; would it be better/different with a newer higher spec camera and would it look different processing through Capture One rather than Lightroom. Below are some old notes reposted along with updates to address my two new questions.

My pinhole set-up I have a simple low cost pinhole adapter based on a modified body-cap type design which fits my Canon EF mount DSLRs. These adapters are readily available for most popular camera mounts.

The focal length was quoted as 42mm (NB almost the same as the Canon EF flange distance which is 44mm) with an aperture of 0.25mm (not easy to confirm). These two parameters give a relative aperture of f168 (by dividing 42 by 0.25).

With the long exposure times required I place the camera on a tripod. Instead of a cable release I typicall…

Edinburgh Zoo

A selection of photographs taken at Edinburgh Zoo, Scotland. These were all taken with a telephoto zoom and natural light. A couple of them by necessity have been shot through glass. Not my usual subject matter but a bit of fun anyway and hopefully some good images.

Monochrome around Oban

Here are a selection of recent photographs of subjects around the Oban area. Taken as digital raws, they have been processed through Capture One only as I continue to explore a monochrome workflow without Silver Efex Pro.

Beyond a short caption I've opted not to say a lot about these photographs, please feel free to imagine your own narrative.

Light pad as a light box

Light pads are thin surfaces fitted with arrays of small LEDs and may typically be used for tracing and drawing applications. Strangely they are sometimes advertised as being suitable for viewing X-Ray images (is this a common need outside a hospital?) and this may suggest that they would also work for viewing photographic negatives.

However there is a problem, the surface is shiny and prone to specular reflections, you can see the reflection of my LED OttLite desk lamp in the image above. Even worse is that the array of LEDs shows through when trying to back light an image, so for example here is how a colour slide (positive) looks:

Not very good but the solution is actually very simple, a layer of diffusion material is needed and this can be done with a sheet of paper. The paper should not be coloured and should be thin, I found a sheet of 41gsm tracing paper works well. To see the difference this makes here's the same slide, now sitting above a sheet of paper:

This is a big imp…

Taking Capture One Pro for a test drive

I've already spent some time investigating Lightroom alternatives and identified Capture One as looking likely but you can only get so far with reading reviews and looking at tutorial videos so it was time for me to get hands on with Capture One Pro. My intention is to put Capture One through it's paces for those aspects that matter to me but not to run through every single function or option and not to compare with Lightroom at a pixel by pixel level. I started out simply by going onto the Phase One site, entering a few basic details and then being emailed a download link.

Once installed I fired it up and created a new empty catalog (tip: I located this on my SSD drive to improve performance). Tip: once installed this is a good moment to review and edit preferences, you'll want to check the "Preview Image Size", it defaults to 2560 pixels, set lower if your screen resolution is lower to avoid having unnecessarily large preview files (NB this preview size is also…

Choosing a Lightroom alternative

Back in 2017 I upgraded my Lightroom for the last time, essentially this was a decision not to move to Adobe's subscription model, along with various miscellaneous grumbles about the quality of the application. At that time I planned to just keep running the old version of Lightroom and keep my options open. However a year on from that I found that my Lightroom Map module had stopped working ( and this prompted me to give the question of switching raw processing engine a fresh look. The map module issue was a simple one, the Google Maps API had changed and Adobe decided they would only fix this on their latest products. In itself this is not a massive issue for me, it's something I could live without but when and what else will stop working with my version 6 Lightroom, dating back to 2015, as my Windows 10 environment has regular ongoing changes and updates?

So what raw convertor could I switch to? I'm …

The Victure HC200 Trail Camera

The most recent addition to my camera armoury is the Victure HC200 Trail Camera, at a special offer price of just £39 this seemed well worth trying.

What you get is a robust unit with waterproof IP66 camouflage effect finish. It can shoot stills as 12mp jpeg and shoots video at 1080HD (in AVI format). It has a PIR type movement sensor that triggers recording and can record at night using it's own inbuilt infrared lighting.

The instructions are not particularly clear but the camera operation is reasonably straightforward. First up is battery installation, it swallows 8 regular AA cells. It also needs a memory card and takes standard (UHS-I) SD cards up to 32Gb capacity, which can easily be formatted from the setup menu.

There are various configuration options; shoot stills and/or video, shoot one still at max res or shoot a short burst at lower res, set the length of the video clip, set the reset time etc. It takes a little practice (and luck) to get the camera well positioned, the…
