I’ve recently purchased a polarising filter for my camera, so I took it out for a test run. You can get quite a difference out in the bright sunlight, though some times it seems to detract from the dramatics of the image. Below is a photo I took of Leeds Canal, with light polarisation on the left and heavy polarisation on the right.

The fly and clouds come out with a lot more texture in the one on the right, and it’s difficult to see at this size but the water goes from a horrible grey to a beautiful blue too.

At first, it felt a little like just under-exposing the photo though. If I wanted to prevent the cloud detail from blowing out, surely all I had to do was drop the exposure a little. But of course that isn’t the case, as can be seen in the photos below.

In the top two photos, I haven’t used much polarisation. In the top one I’ve used the camera’s recommended settings, and in the second one I’ve sped up the exposure a few notches. In the third one I’ve put it back to the camera’s recommended setting, but used heavier polarisation.

As you can see in the third one, I’ve obtained the rich detail of the cloud, while still maintaining the vibrant face of the building, and captured much more detail from the block of flats behind it too.

I tried my hand at panning so that I could capture cards speeding by. The idea behind the technique is that you pan the camera as the car drives past, thus blurring the background while keeping the car in sharp focus.

I was using my 24-105 f4 lens. Ideally I would have had my 70-200 f2.8 so that I could blur the background even more, though whether I could get down to f2.8 and still keep an exposure of 1/200 I’m not sure. I got better results when I turned off my image stabiliser (because the camera stops trying to fix my panning), but my better lens also has a specific image stabilising mode for panning, so I would like to give that a go.

A feature that many sports photographers like to take advantage of is back button focusing. I was trying this out at Yorkshire Wildlife Park recently and it has its advantages. The idea is that you can use a button on the back of your camera to focus, rather than have the camera focus when you press the shutter button half way down.

The advantage of this is that you can focus when you want to, and then not worry about the camera re-focusing if you take your finger of the shutter button.

For example, I often press the button half way down to get my focus, then re-compose the shot because I don’t want my focal point to be right in the middle of the frame, then take the photo. This means I have to keep my finger on it the whole time, and need to re-do these actions if I want to take additional shots. With back button focusing, I focus using the button, then point the camera somewhere else and take as many shots as I like.

Some cameras let you re-assign the exposure lock button, but your higher end DSLRs will have an “AF-ON” button you can use to activate the auto-focus without having to re-assign a button – useful if you use exposure lock as well. In which case, all you need to do is stop the shutter button activating the auto-focus. I’ve done a video showing you how to do this on the Canon 6D…

By the way, the video is the right way round, it’s just the thumbnail that is wrong.

Last Monday, we went to the final session of our photography course.

Overall, it was well worth attending. I’ve read plenty of books on how to use my camera, but having in person tuition and going through the exercises is far better to getting knowledge into my head, even compared to going out and practicing what I had read about.

It did end quite expensively though – I’ve acquired two new lenses since starting the course and added flash studio kit to my Christmas list, so presuming Elina gets me that as well as my iPad 3 and iPhone 5, that is going to end expensively for her too.

Turns out, it’s reasonably easy to remove windows, in Photoshop.

I used my birthday gift vouchers to buy a new 50mm f/1.4 lens for my camera. It’s excellent for doing very shallow depth of field, although, on reviewing the photographs, I’ve realised I went far too far with the shallow depth – sometimes it was narrower, even than the object I was actually trying to photograph! Looking forward to playing around with this lens a lot more.

I’ve been meaning to do a photography course for a long time. But every time I look into it I realise I’ve just missed an intake or it’s at least some ridiculous amount of time until the next one starts.

However, being determined to get it done, I made an effort to hound Leeds City College – and I do mean hound because getting information out of them is like getting blood out of a stone. They simply don’t know when the courses are going to be running or provide you with any information on them.

Never the less, I managed to get myself and Elina booked on one, and we had our first session last Monday. The course costs about £150 I think, and for that you get ten sessions of two hour tuition, which seems reasonable.

The first session was general introductions, but was by no means non-informative. We discussed the problems we were having and what areas we wanted to focus on in the first part of the session and then dived straight in to the course material and practice exercises.

By the look of the schedule, it’s very focused around the kind of photography I want to do as well, so I’m very much looking forward to it!

I recently got a flash gun for my camera, so I’ve been taking lots of pictures of Moomintroll.

Although I really love my Canon EOS 450D, one thing I have noticed recently is that I’m not taking as many photos as I would like to because it’s particularly convenient to take my camera clubbing or to gigs where they search your bags using ambiguous policies.

To counter this I decided to get my self a cheap camera which could serve such a purpose. I finally settled on the Sony DSC-W350 which for under £100 gets you 14 megapixels (two more than my 450D as it happens) and easy point and click operation in something that will easy fit into my pocket.

Size was really my primary concern when making the decision and the W350 holds up well. It’s about the same size as a credit card so if you’re thinking “wow, it’s only slightly better than a paperclip” I should point out that that is a very big paperclip lol.

It comes in at a depth of 17mm, just slightly shy of being twice that of my iPhone 4 at 9.3mm. That seems a little bulky in comparison but it is perhaps an unfair test to compare it to the world’s thinnest smartphone, and it manages to come in thinner than most of the competition I looked at with most of the slim cameras in it’s price range coming in at around 23mm.

Picture quality is mediocre. It is significantly better than my iPhone 4 but having shot with nothing but a DSLR for two and a half years now, my quality expectations have come to rest somewhat high. Just viewing the photos on my 23″ monitor you can see the photos aren’t quite perfect but then for a compact under a £100, you would have to be very demanding to expect them to be – if I need print publication-quality photos, I’ll take my real camera.

What I do like is that the wide-angle lens produces usually warm images in comparison to my DSLR and as the camera’s main use will be taking shots of my friends while we’re out, this actually makes for more than adequate results for what I need it to do.

After almost a year in development, we are pleased to announce the launch of Atheist Stock!

Atheist Stock is a stock photography website designed specifically for atheist, humanist and free-thinking societies. On the site you can find a wide selection of high-quality photographs to use in your advertising, websites and print material when designing creative for your group or society.

So whether you need a photo of groups at work and charity work to Conway Hall and Richard Dawkins, we have the image you need. They are all available as high quality – good enough to print – almost all at resolutions as good as you would find on professional stock photography websites.

Best of all, they are all available completely free to free-thinking groups! Just contact us with information about your group and will we provide you access. So why not check out our collection!
