Big weekend for the Calgary FreeRiderz

Back in September I was given the honour of becoming the club photographer for the Calgary FreeRiderz freestyle ski team. This past weekend members of the team competed in the provincial Slopestyle championship.  On the Men’s side there were 72 competitors including 5 members of the freeRiders.  Freeriderz had a very strong showing Kyler Tritter placed 3rd,  Cameron Duncan placed 1st in his group, Colin Hendrickson placed 4th  in his group and 5th overall, while his brother Mark placed first in his group and 1st overall.  It looked like so much fun – for or second or two I thought about debuting  the skiless snow pants tumble event – but at the last second I did manage to dig a boot in and save myself – unfortunately all photos of the mishap were mysteriously deleted.

 

Here are a few teaser photos – full video will be ready in a few days – just awaiting the sound track from RadioFlyer can’t wait to hear the new tunes

lament for lethargy

getting ready for valentines so nothing really appropriate for posting here (picture wize ). I have finally completed the cull of the pictures for the portfolio review – I came to the conclusion that, in many ways, I had been complacent and somewhat lazy. I have been in a bit of a rut in my design. I think that is because, until, now I have not wanted to have the second meeting to involve the subject in the design process of the session.  I have been contemplating this for a while . While I understand that some people feel that it is an inconvenience coming in to the studio twice for one photo session , but in the past when clients have not wanted to come in for the design session, the client will come in and the see some of the pictures on the wall  of the studio and say  gee I want something like that, but they are not wearing the right clothing, or I have they want an outdoor instead of an indoor picture. I have decided that this is exceptionally important part of the process and will now be part of every

 

At any rate this week’s blog post is answering another question. I was asked about exposure  – how do you determine the right exposure for a picture. Sorry to say that the answer to that question is  – it depends. Exposure for a picture is rather like filling a bucket with water from a tap.  You have several options, depending on your objectives in creating the photograph. In the digital world exposure is created by an equation something like exposure=iso ( aperture x shutter speed). In the film days iso – or sensitivity was set by your choice of film – but in the digital world you have a nifty dial. Think of  the picture like a bucket you would like to fill with water . at the tap you have a few options when it comes to filling that bucket – if you are interesting in filling it fast – you can open that tap wide open for a few seconds . if however you are more interested in filling that bucket accurately then you can open it up just a little for a longer period of time to make sure you get it exactly full.

The same is true for a photograph. If your objective is to stop motion or time – then the part of the equation you are most interested in – is the shutter speed. The faster the shutter speed the more you will stop time.  So if you  are shooting a picture of a car driving by, and you want the tires stopped – this is accomplished (either with a flash – ask me if you want more on this – or ) but having a fast shutter speed – the equivalent of opening the faucet to fill the bucket.

Another option is maybe you want to control how much of the picture is in focus – maybe  you want to have from the foreground to infinity (hyperfocal) in focus – or maybe you want to have only a selective part of the picture in focus and the kewl blur (bokeh) everywhere else .( I am a bit biased – but I think that this is where Canon has an edge over Nikon). This focus/blur ratio is controlled by the aperture – of the fstop (partially a factor of  your lens choice as well)  f stop is a ratio of the size of the lens opening/ the length of the lens . so the smaller the f stop – the more open the lense is ( a 50 mm lesn that is open 50 mm will have an f 1 where as a 50 mm lens open 25 mm = f2).  The smaller the f stop the less that is in focus – the more kewl blur.

So the answer to what is the correct exposure depends on what is your objective – in the old days thay used to teach the sunny 16 rule – if you were shooting out doors on a sunny day your exposure for 100 iso film at 1/125 of a second was f16. Great for landscapes – that is a pretty tiny opening – lots of depth of field pretty quick 1/125 of a second will stop most action . However if you are shooting car racing – maybe you want to look at say mayb1/250 of a second so you need 2xs as much light (each f stop is 2x ass much light) so maybe you would look at f11 at 1/250

Or maybe you only want an eye to be in focus f stop is more important to you maybe you want say f8 at 1/500 .  or f 2.8 at 1/2000 of course some of this depends on your lens choice which is another question all together . Hope this helps, If you have any questions please send me an email .
