To create this composition i used white backgdrop, gray laptop, white wallpaper as well as strictly geometrical lines hand rule of thirds and apple logo in the middle
Here it took many takes to get the right result. I experemented with shutter speed and apperture, and tried different combinations, but found out it is too dark to get the result i want. So Ihad to increase iso, that caused noise in tha dark areas.
To capture the smoke and light in the night I used ISO 3200, shutter speed about 30 seconds, and F5.
This picture was taken in a completely dark room at a nighttime, with only ambient light coming from the street. It took 90 seconds to capture ths. apperture was 5.6, lens 50mm. This resulted very short depth of field, the sharpest part is only where the front doors are.
Here we used a flash and a flashlight. with about 10 seconds exposure.
