Free Photography Courses – Digital Color Management

We discuss here Free Photography Courses – Digital Color Management. As you know, digital photography mainly consists of an additive color mix. The primary colors for digital processing are red, green, and blue. Historically, red-setting on color gelatin prints was performed by overlapping magenta and yellow filters. Adjustment of magenta and yellow gels also affected exposure values.

In digital curve settings, red has its own channel. What most photographers don’t know, and what you should really ponder, is that one should adjust the layer of the composite RGB curve to match the opposite of the red channel curve.


1: the right film

Description: Photographers had to load their camera with film rated for the primary light source to be used with their subject. For example, a landscape project would require a color film in daylight. Free Photography Courses – Digital Color Management

2: precise film processing

Description: Processing toxic color photographs requires very precisely temperature-controlled chemical baths. There is little margin for error due to this. Every step in film processing requires maximum precision and must be very well understood by the developer.

 3: expert engraving

Description: Engraving experts use layers of color gels to adjust the lamp that will expose the colored jelly paper with the image in the film negative. Adding or removing the red color of the lamp also affects the amount of light, therefore requires adjustment of the exposure values. Adjusting blue or green colors does not affect exposure values ​​when making color gelatin prints.

The color process has completely evolved digitally. In addition to the actual exposure with a camera and lens, the film’s steps have disappeared. Now there are new steps, and understanding evolution can only benefit the image taker! Get a panoramic view of the entire workflow for realistic colors in digital photography.

Digital color management

Take a reading with a calibrated light meter in the associated lighting environment to calculate the most accurate exposure value

Capture a RAW image of a color target in that lighting environment

Postproduction: Set the correct color temperature of the image and create a curve fit so that each swatch matches the corresponding theoretical values ​​of the Color Checker. This could be done on a calibrated monitor, but that is not necessary.

Make a print with a raster image processor, making sure to configure the profile to match the loaded paper. Also, the profile should ideally be one created specifically for the light source under which your impression will be displayed
You should be aware that historically it has been easier to produce realistic color on film than digital, but there is still much more control and possibility to achieve greater realism with greater precision. In the days of the film, there was no color objective that could aid the printing process. With digital, we can be absolutely sure that a particular color in a photograph represents its theoretical value.

If you educate yourself about the photographic medium and its history. So,  you will become a more complete photographer. With more knowledge, you can help teach others who are interested in it. But, Get motivated to embrace the digital medium and learn all you can about how it works, evolving from traditional film photography.

I excelled at art school by harnessing my passion for color and photography. Therefore, I studied and learned on my own outside the academy applying new knowledge. But, consider myself an expert in color correction and hope to share the wisdom with you.
