EOS-1D Mark IV with WFT-E2 II in HTTP / web server mode

Canon first introduced Wireless File Transmitters to it’s cameras with the WFT-E1 for the EOS-1Ds Mark II way back in history, and since then has provided WiFi transmitters for most of the advanced and professional bodies. With the introduction of the EOS 7D and the WFT-E5 several new and updated features appeared and also several …

Speedlite shoots 90 kilometres

During a recent individual training the topic of flash power came up, the photographer I was talking to was saying his flash wasn’t powerful enough, even though he had a Speedlite 580EX II. I suggested that he try something other than ISO 100 for his flash pictures. The Speedlite 580EX II has a guide number …

Using EOS Utility to control your Speedlite flash

I’m currently down in South Africa about to go to Cape Town for a couple of days, but for the last few days I’ve been busy at the Sandton Convention Centre presenting on Canon workflow software and also a session about my photography with Speedlites and other light sources.

Just recently I shot some location pictures in a parkland area in Oxford. Travelling light with no assistant I …

Did you disable high speed sync without realising?

This is a cautionary tale about how experimenting with custom functions can significantly change how your pictures look. In this case I was getting very overexposed pictures in aperture priority (Av) when using a flash and high speed sync (HSS). Setting high speed sync on your flash allows you or your camera to select a …

Crop circles

The latest version of Digital Photo Professional has introduced a feature that I really can’t think of a use for, circular crops. What’s more the way it works is a little strange. A circular crop of an image makes sense if it’s to be framed and used with a circular mount card, also if the …

EF25 Extension tube with EF135mm f/2L USM lens

Sometimes you just need to get close, really close, to make a great picture but what if close is less than the minimum focus distance of your lens? You can add an extension tube between the camera and the lens, this moves the lens further away from the sensor, but has the effect of reducing …
