Canon 5DSR

The latest, biggest and baddest addition to my photographic arsenal is the Canon 5DSR. This beast of a camera shoots at a whopping 53 megapixels (effectively 50.6), more than double the resolution of the 5DMKIII, three times the resolution of the T4i and over four times the resolution of the XSi. Part of the reason I splurged on this camera was the desire to utilize the new Canon 11-24mm lens to the fullest, which means squeezing every pixel out this body/lens combination.

In short, the 5DSR is basically a 5DMKIII on steroids, it’s virtually the same exact body with a couple tweaks in the menu, more vibrant colours and overall better colour science with much more powerful Dual DIGIC 6 processors. The tradeoff is that the autofocus is a hair slower than the 5DMKIII and the 5DSR can only shoot 5 frame per second vs the 6 frames per second the 5DMKIII can shoot. All in all though, for landscape, weather, sky and studio portrait photography, the 5DSR is a powerful tool!

If you’re wondering which camera I give preference to, don’t worry, the 5DMKIII and T4i still get plenty of use. I basically keep a different lens on each body so I can quickly achieve the photo I desire without having to switch lenses. Wider lenses I tend to keep on the 5DSR, midrange lenses on the T4i and zoom lenses on the 5DMKIII. I found that the autofocus of the 5DMKIII is superior to the T4i and yields very good results when shooting something soft like a tornado at 150-200 millimeters which might not have rigid contrast. The T4i does very well with intermediate lenses and gives the 24-70mm lens a little more reach while maintaining autofocus. The 5DSR is slower than the MKIII but faster than the T4i and yields a lot of information that can be used to crop wide-angle shots.

Enjoy some sample photos I’ve taken with the 5DSR below!

Photographic Accessories

In addition to the DSLR bodies themselves, I have an array of filters, polarizers, plate holders and trigger / remote systems.

Having a good quality, responsive SLR is the first step in taking great weather photos, the next is having the tools that can take your camera to the next level.

Photographing storms is never a quick easy process, yet storms by their very nature require you to be a fast, accurate and confident photographer. You need your camera to be focused correctly, the exposure to be accurate, white balance acceptable or faithful and a steady hand or tripod to prevent motion blur/jitter. Only after all these factors are correct can you start taking photos and make adjustments to composition, and other elements.

Once you’ve mastered the basics, and learned how to use your lenses effectively, then you can add things to them such as circular polarizers to deepen the blues in the sky and make the clouds pop out.

You can also add graduated filters to help balance the bright clouds against the darker foreground. If you’re really brave, you can combine polarizers, neutral density grads and even coloured filters to make things pop or create hyper-realistic art.

I say art because the instant you push your photo beyond a faithful true to reality representation, it’s no longer realistic to what was there but a form of pseudo realism. Think about it like this, if I use a filter to make the sky pink and the pink sky somehow balances perfectly with a big white thunderstorm against a field full of yellow sunflowers, it’s acceptable as a cool photo, but it’s no longer realistic. I’ve tricked your eyes into believing something that’s probably impossible and further to that point, manipulated reality to create something that I feel looks better. The photo is partially representative of what was there since I did not remove elements but it’s not faithful to the reality of the moment since I added false colour to the sky.

So remember, tools like filters and grad to help you turn your photos into art, or make them more representative and faithful to what was there. It all depends how you use them.


Vaavud Sleipnir

I’m one for gadgets and the Vaavud Sleipnir is the perfect gadget for any weather nerd! I was familiar with the whole crowd funding program around Vaavud and their original wind meter but it was not until I wandered into Fogh Marine in Toronto that I saw the Sleipnir sitting in a cabinet.

I had a choice of three hand-held anemometers ranging from a standard Kestrel to a Davis ultrasonic device but the Vaavud unit was the cheapest of the three and had one major benefit, it could store and share the wind data. The Vaavud needs a compatible phone to make the unit work since it basically uses the microphone/stereo/trrs jack to send data to an app that turns it into usable information.

During my initial testing of the Sleipnir I was very impressed with the directional accuracy and velocity data resolution. I compared it against a few more expensive anemometers I have including my Davis Vantage Vue and a brand new Vortex Inspeed unit, and the Vaavud was basically on par with both units but additionally able to catch some of the more subtle micro gusts.

The unit as a whole is super responsive and seems to take measurements several times a second catching all the smaller gusts. This data can then be graphed in the program, shared to a larger map and database or even automatically uploaded to DropBox. It’s a great device to keep in your pocket, or somewhere in your car. The one detriment is that it seems to eat up your phones battery and while most all iPhones seem to work fine with it, my Android devices are hit and miss. Plus, if you’re using it in really wet conditions then you have the issue of water getting into your phone by leaking down the pin into the audio port and damaging the internal electronics. Obviously you have to use it with care and caution or for shorter periods in rainy weather.

For my storm chasing and weather needs I developed a vehicle mounted solution. Originally I had simply stuck my iPhone and all to the roof of the car by using a suction mount and RAM X grip. While it works perfectly, the phone is still exposed to any elements and not easily accessible. Plus I accidentally drove away a few times with the phone up there and had the mount failed I would have been out of a phone and $600!

The solution was to purchase a 2 meter long StarTech TRRS cable from and keep my phone/tablet inside the vehicle while leaving the Vaavud unit mounted outside. My initial testing reveals that the Sleipnir operates just fine with the extension cable. I have yet to really test how waterproof or weather/dust resistant the anemometer is but at last I can now mitigate any risk to my phone/tablet. This is especially important when your inside of a powerful thunderstorm.

The one draw back is that the digital compass data is lost when inside the vehicle. This means the directional wind component of the Vaavud becomes useless. But overall that’s a small price to pay for having recorded and geotagged wind data that will catch all those smaller but important gusts.

I’ll continue testing the vehicle mounted unit and update the blog with my findings. Once the weather is warmer I intend to build a small 30cm tall post to get the anemometer as far away from the vehicle body as possible to increase accuracy.

You’ll find a short video below showing fellow storm chase Colin using the Vaavud in 80 km/h winds.
