Chemical Photoshop for Emulating Film and 100 year old processes

In summary, Autochrome is a photography technique that combines two layers on glass - an RGB screen and a BW emulsion - to create color photographs. By separating the image with an RGB filter, the BW emulsion records the tones and creates a color photograph when developed. To create a software that can emulate this process, one needs to understand the curves of the dyes and BW film, as well as the chemicals and emulsion sensitizers used. One suggestion for achieving this is to look into creating a custom photoshop plug-in through Adobe's plug-in API.

Autochrome is a photography technique which all details forgotten 50 years ago but counted as the best color photograph technique.

There are two layers on glass , one RGB Screen and second , a bw emulsion. When RGB filter separates the image , bw all color sensitive layer records the tones. Than all developed and you can see whatever RGB filter and bw emulsion recorded as color photograph.

I worked on subject and learned the dye numbers , their ratios and bw panchro film details.

The important thing is to know the curves of these dyes and curves of bw film.

I thoght if I could learn many chemicals and emulsion sensitizers spectrums , I could make a photo engineer software. every curve would tell the colors and their ratios and emulsion sensitizers would result as process emulating software.

What do you advise ?

Thank you ,

A custom photoshop plug-in could probably do that. You should look at the Adobe website for their plug-in API.

This is vaguely akin to "Sepia" filters only a bit more sophisticated.
 

Related to Chemical Photoshop for Emulating Film and 100 year old processes

What is "Chemical Photoshop for Emulating Film and 100 year old processes"?

"Chemical Photoshop for Emulating Film and 100 year old processes" is a digital editing technique that mimics the look and feel of traditional film and photographic processes from the early 1900s. It involves using various chemical filters and adjustments in Photoshop to achieve a vintage or aged aesthetic in photographs.

How does "Chemical Photoshop" differ from other digital editing techniques?

Unlike other digital editing techniques, "Chemical Photoshop" focuses specifically on replicating the characteristics of film and photographic processes from the past. This technique involves using specific chemical filters and adjustments to achieve a unique and authentic look.

What are some examples of "Chemical Photoshop" techniques?

Some examples of "Chemical Photoshop" techniques include using sepia or cyanotype filters, adding grain and noise to images, and adjusting contrast and saturation to mimic the color and texture of old film.

Is "Chemical Photoshop" suitable for all types of photographs?

While "Chemical Photoshop" can be used on any photograph, it is most commonly used on images that have a vintage or nostalgic subject matter. This technique may not be suitable for all types of photographs, as it may not align with the desired aesthetic or theme of the image.

Are there any limitations to using "Chemical Photoshop"?

Like any other digital editing technique, "Chemical Photoshop" has its limitations. It may not always produce the exact same results as traditional film and photographic processes, and it may require some experimentation and trial and error to achieve the desired look. Additionally, this technique may not be suitable for high-resolution images, as the added filters and adjustments can decrease image quality.
