I’ve recently start experimenting with digital photography. I’ve owned a digital camera for several years now but I have only just started to play around with more advanced techniques of manipulating digital pictures.
My first experiments were with HDR, which is the result of taking multiple exposures of the same scene and then combining them on a computer in order to obtain a hyper-real rendering of the scene… obviously there is a little more to it but I’m not going into that here, that’s what Google is for. There are several good applications out there which make the process of generating a HDR image incredibly simple. You don’t even need a big expensive digital SLR camera, even my Canon IXUS 500 is capable of exposure compensation, which is the key to HDR.
Tilt & shit
The other technique I’ve been wanting to have a go at is a digital Tilt & Shift effect. Traditionally the tilt & shift style of images was generated in one of two ways. Either it was created when taking macro photographs of model scenes (e.g. model railways) using a very short depth of field or it was created using a bellows adaptor on a camera with interchangeable lenses (e.g. an SLR). There is however a much easier method than these for digital photographers… photoshop. I found a great four step tutorial on RecedingHairline.co.uk the down side is that so far I have only found one of my pictures that was suitable to try this effect on.
What I wanted was a source of pictures that I know I would be able to play around with and then post on the internet for other people to be able to see what I was doing. I wasn’t until today that I realised that the very site I had been hosting my images on was also an almost limitless (relatively speaking) source of material to work with. I remember that I released my images on Flickr with a creative commons license and that it must surely be possible to search for other images with a creative commons license on Flickr. And sure enough there is. Now when I see a new digital manipulation tutorial I have no reason to not have a go at it, all I need to do is use the Flickr Creative Commons search to find a suitable image to play around with.
