We usually take photos to grab the moment.
A few plan ahead, and wait for the moment to happen.
Fewer still are those who create the moments themselves.
Often these photos are post processed to make it look better.
Some will go further of removing some elements to get the desired look.
Then there are those who would combine several images to create a totally new graphic.
In all these scenes, we consciously look for the right composition, before we press the button.
Instantaneously in snapshots, and more planned and specific as we delved deeper into post processing.
But when one reaches for the final frontier, when one strives to fully edit an image, then one needs to look beyond the good composition.
One would need to Imagine the Photograph.
Imagining the Photo is looking at it from the perspective of the finished image. Instead of consciously looking for the best composition of the present scene, we treat them as a separate element that will fit into the different final photo.
Hence, depending on the target outcome, we may opt to adjust the perspective, lighting, view angle etc. of scene being photographed.
This technique can used to composite individuals into a group photo.
In the sample below, a single box is made into a group with a breakdown of how the shoot was planned.
Although this technique cater specifically to editing, being able to Imagine the photograph is like an open gate to fully understanding and planning a composition, and IMHO, something worthwhile to practice and keep in ones bag of techniques.
