This is an idea that has been in my mind for quite a few time already but that until today, a sunny with cloud intervals in the sky I haven’t realized. So this morning, after being doing a few thins I had to wrap up I took my EOS 350d with the 18-55 lens and with my bike I went for a photo ride around Ipswich.
The topic I have chosen today it has been something very tipical in this country, the pubs. I haven’t taken a photo of all of them but I think that as a first approach you can figure out how they are. But let’s focus on the HDR which is what I wanted to try today.
As we can see on Wikipedia, this is a brief definition of HDR: In image processing, computer graphics, and photography, high dynamic range imaging (HDRI or just HDR) is a set of techniques that allows a greater dynamic range of luminances between light and dark areas of a scene than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.
The way you do it is taking the same picture 3 times at least with a different set up on the camera, meaning that you take a normal photo as if you only want to take one photo of the scene and then you take a high exposure and a low exposure of the same item, therefore it is highly recommendable the use of a tripod when you make this kind of photography. However if it is in daylight and the speed you use is fast enough you can take them without it.
To get the more possibilities and the best marked effect with HDR you must shut your photos using RAW format. Then the image is not compressed and it is easier to handle into a wide range of colours and other settings by the program you use. As the photo is taken in RAW, the weigh of this one is way more than a compressed one in JPG as many people use to take them, so have this in your mind because it is esasy to notice that we are running out of space in the card. To compose the final image that will produce the effect. I have used Adobe Photoshop CS4 in Mac OX to compose the HDR photography. The way you do it is really easy, as the programs does all the work for you appart of the postprocess that you would like to add to the result. I haven’t done anything after that because I liked the result and because I am still learning this work.
There are more examples of my ride into my flickr gallery so I invite you go around and have a look to them
