Black and White Iso photography with the lowest possible ISO possible. While this is something that most of us do in color photography it is particularly important when it comes to black and white where noise created by ISO can become even more obvious. If you’re after this ‘noise’ (or grain) you can always add it later in your post production – but it’s harder to go the other way and take noise out, The negative aspect of RAW files is that it needs to be processed later. If you use RAW files, your computer, rather than your camera will process the records and generate a picture file from it, For black and white photography, use the lowest ISO. When you use high ISO the noise will become more obvious. Noise in photography is like the “grain” in film, where the film doesn’t become as smooth as you’d wish. The higher your ISO is, the more unpleasant dots will show in your photo. Therefore shady and dim days are actually great for black and white photographs.

Modern cameras on automatic will try to avoid the long shutter speed.
To compensate for the smaller amount of light gathered, it either opens the aperture more, which will let more light through the lens, or, when the aperture can not get any bigger, make the sensor more sensitive.

Frame your subject, try to hold the camera as still as you can, and take more than 8 pictures.
Some of the pictures might have a little bit of motion blur, so it’s nice to have a few to pick from.

Each picture should be kind of dark like the one below.

Take all the pictures in one run, else your second bunch of pictures might not align well enough with the first, and you’ll have to cut alot off at the edges.

When you take a picture, you expose the sensor in the camera, so that light reflected from the subject, can hit the sensor and be registered as an electrical impulse.

This happens over a period of time. A longer period of exposure lets more light hit the sensor, which gives brighter images, Unfortunately, during this exposure time, the subject might move compared to the camera, Logically this will place the object in a new spot on the picture taken.

The object will therefore appear on the final picture both where it was at the start of the exposure, but also where it was at the end.
It will also leave a trace of itself between the two points, and looks transparent because of whatever being behind the subject at the beginning of the exposure, is visible to the camera at the end of the exposure.
