The Value of The RAW file format
One of the most significant image output enhancement options is often ignored by amateur as well as many professional photographers, – the RAW file format.
Shooting in RAW is perceived as extra work, more data to store and unnecessary since we all know how to shoot good jpegs . . . right? We don’t ever make an exposure error or concern ourselves with color temperature. Hummm.
Here is an example:
Photographing people is fluorescent environments . . . as I recall many, many corporate and small business offices are lit how???
I created this image in one of the worst lighting scenarios on the planet – an office with fluorescent light – with a digital camera set to Program Auto Exposure mode.
Image shot in RAW - no Correctio
Problem-
• Overhead light casts shadows under the eyes and tends to make people’s faces look flat and tired.
• Fluorescent light casts a greenish yellow color, which makes the skin look pretty bad.
Image file shot in RAW - corrected for flourescent
Solution-
• I used a fill card to redirect the diffused fluorescent light to fill in under the model’s eyes, nose and chin.
• I removed the greenish yellow cast from the fluorescent light source by clicking a button in Photoshop.
The Camera: Set your DSLR to 400 ISO – from the camera menu, select the RAW file format - put your camera on a tripod – elevate the camera to slightly higher than the subjects face – use the longest focal length available between 85mm – 135mm.
The subject: Place your subject under the edge of a fluorescent panel – have the subject hold the fill card to redirect the light to fill in under the chin and the eyes – take lots of pictures – work with the subject to get a range of emotions – do the left & right side. Pick the one with the best expression!
Happy Shooting!
