This is also a working description of what exposure fusion or HDR consists of
Let us have a real life run through. Here is a den with a window scene, I have taken 9 different exposures as you can see below. Your wedding photographer, Realtor next to you with his new digital camera, or neighbors son will not give you a better image then the best one presented. And the walls will not be straight.
This means that if I take 50 different pictures of a property, I now have to process 450 images. And we are not even talking about the 360-Virtual Tour.
I currently use a Canon 5d MK II, each image is 21 mega-pixels on a full frame sensor.That means the end picture I provide was merged/combined from 189 mega-pixels of data.
|Here is the raw combined image, but we are far from done.|
|Here it has been adjusted to where I want it, a little contrasty but that will be dealt with later.|
|Now we are in Photoshop and making sure the walls are straight even though they looked good before.|
|Next step is to correct for the lens distortion, this straightens any bowing effects from the wide angle lens.|
|Our final crop.|
|Here we bring back our outdoors scene. Then a final contrast adjustment and save.|
