High Dynamic Range or HDR Photography

I've always been curious as to what HDR photography is, but I'd never attempted it until recently.


Aberdeen, near Union Terrace Gardens

It's pretty easy once you grasp the concept of how to do it.

You need at least 3 images. One with a normal exposure, one overexposed and one underexposed. (You can take a couple extra either side). The over exposure will get your highlights and the underexposure will get your shadows. 

To take 3 identical images, you will need a tripod and a sturdy one at that. Adjust your camera to the light you're shooting in and take your normal image. Then up your shutter 2 stops and capture the next image for your underexposed image. Then put the shutter 4 stops down, so it will be 2 down from your original image.

I took the images from the cinema using 7 images each with a 5 second difference within the shutter times. 

Once you have all your images, it's editing time. I used Photoshop, however it can be very slow to load but I don't have any other HDR software. 

So in Photoshop, got to File>Automate>Merge to HDR Pro.. which will open a small menu and then select the images to open. 
HDR Pro will then come up and you can edit the image's saturation, highlight and shadows how you seem fit.
