Technical notes


I used a Canon 5D Mk 3 camera with a 70-300mm DO image stabilised zoom lens,a 50 mm f/1.4 prime lens, and a 24-105mm f/4 image stabilised zoom lens. The 5D is a "full-frame" camera and so the focal length factor is just 1.0. Many of the images with the 24-105mm lens were taken with a polarizing filter to bring out the clouds in the sky.

I used one 32GB camera memory card; a "600x" UDMA CF card and a 64 GB SD card (the camera takes both at the same time). I shot with the CF card and at the end of the day I copied, in camera, the images from the CF card to the SD card and then put the SD card into the built-in slot in my HP laptop computer. I downloaded the images to this computer nightly and imported them into Lightroom. I always shot in RAW and viewed the images in Adobe Photoshop Lightroom. Unusually, I had time on this trip to rank and process the images during the trip. The relatively light, mid-size, HP proved quite adequate for this task, even with Lightroom's adjustment brush. Consequently these images are posted within days of returning unlike the usual 2 month delay.

I used an HP laptop computer that is relatively small and light with a dual-core processor. The internal solid-state hard drive was fast but didn't have much room for photographs (the 5D Mk3 produces RAW files of 28 to 30 MB each). I used an external SSD hard drive for image storage. For backup I used the 64 GB SD card.

The images were imported into Photoshop Lightroom daily. Lightroom ran very well and it was easy to add keywords and captions to the images, and rank and develop them “in the field”. When we got home, it was easy to copy the images and their metadata into Lightroom on our desktop computer, by connecting the external SSD hard drive to the desktop computer.

I do not delete many images, either from the camera or the hard drive, unless they are a total disaster. I do not have the time to examine the photos carefully (nor a large screen – the laptop is 15 inches) and I also find that my opinion of some images changes over time. So, I bring almost everything home.

I took two rechargeable batteries for the camera. This was satisfactory.

Overall, the trio of digital camera, laptop computer, and hard drive worked, for me and my needs.

Once home, I import the images from the laptop external hard drive to a desktop computer and use Adobe Lightroom to sort out any "duds" and rank the remainder. Those that I plan to post to the Web are moved to a Lightroom collection and developed using the develop module in Lightroom. Where necessary, I use Adobe Photoshop Elements or CS6 to make additional changes. Finally, images are resized and saved as jpegs using Lightroom's export feature.

I wrote the Web site with Dreamweaver and manage it with Dreamweaver. I used Adobe Cold Fusion programming to simplify reusing code from exhibition to exhibition.
