Last week we learnt the technique of bracketing. By taking several shots of a scene or object at different exposures the best part of each shot can be combined to get the same detail over the whole image. For example, the following two photos were taken from inside but one has so much light coming in that you can’t see outside and the other is underexposed but shows the garden beyond the windows.
Too much light coming in to get detail inside and outside at the same time
Has outside detail but interior is too dark
By copying the windows from the darker shot to the to the overexposed shot the interior looks more interesting. This technique is used where there is strong contrasts in the light.
The result of bracketing
We also learnt the technique of blurring in Photoshop (Filter…Blur..Motion Blur). By taking a still shot and dividing it into a background layer and an object layer, the object layer can be copied and blurred. Then the layers are rearranged (Background, overlaid by blurred object, then overlaid by still object) to give the impression of the object moving.
