One of the special challenges in altering the appearance of light digitally is to create the effect of bright, sharp sunshine, but there is software available that will help. One of the fundamental question in image editing is how far you should go – that is, how far you should move away from the original as it was shot. In principle, anything and everything can be changed; in practice, it depends what you personally feel is acceptable and on how much effort it is worth to you.

 

With daylight photography, the major hurdle is bringing sunshine into the picture. If you have ever waited for a break in the clouds to brighten up the scene, you will know that there is a demand for this – and to an extent this can be done digitally. The problem, as you can check by comparing two versions of the same view, overcast and sunny, is that direct sunlight affects everything and in many ways, down to tiny shadows and the glow reaching into shadows from sunlit surfaces.

 

Although clouds reduce brightness when they block the sun, the amount depends very much on the type of cloud. If the clouds are indistinct and spread across the sky, the light loss is on a simple scale from a light haze (as little as 1/2 a stop less than clear sunlight) through thin high stratus to dark gray, low clouds (up to 4 or 5 stops darker, and more in exceptionally bad weather). With distinct clouds, however, such as scattered fair-weather cumulus, the light levels can fluctuate rapidly, particularly on a windy day. Light, white clouds usually cause a simple fluctuation of about 2 stops as they pass in front of the sun from bright to shade in one step. Dark clouds with ragged edges, or two layers of moving clouds, cause more problems, as the light changes gradually and often unpredictably.  In the first case, two light measurements are all that is necessary – one in sunlight, the other as a cloud passes – and once this is done, you can simply change the aperture from one to the other, without taking any more readings. In the case of more complex moving clouds, constant measurement is essential, unless you wait for clear breaks and use only these.
