help in judging if images are exposed correctly or not, first calibrate the brightness of the monitor
by comparing an actual image with the same image on the monitor, and adjust the monitor until it
matches the brightness of the actual image.

When using strobes to take images, the kind of light exposing the film/image sensor increases from
just one type; natural Ambient Light, to two types; Ambient Light and Strobe Light. Therefore,
when Strobe Light becomes a factor, in order to expose the image according to your intention, you
must first image in your mind:
1) The combined total exposure amount of Ambient and Strobe Light
2) The balance between the Ambient and Strobe light in the total exposure amount, and
how to match the camera parameters for each subject and shooting condition to
appropriately control the outcome.
Considering the light exposure from the Film or Image Sensor's perspective, the characteristics of
Ambient and Strobe light can be compared as follows.
Ambient Light
Comparatively weaker than strobe light, but exposing for the whole time the shutter is open.
Exposes subject, foreground and background equally based on the ambient conditions.
Strobe Light
Comparatively stronger than natural light, but only exposes for a brief instant while the shutter
is open.
Because much of the strobe light will be absorbed by water, amount of strobe light reaching the
subject, foreground and background is different. Objects closer to the strobe will receive and
reflect more strobe light. Distant objects or background may not receive any strobe light at
all.
