Photochrom is a printing process that uses an image printed on lithographic stone to transfer color to a photographic negative.

The resulting print can then be used to make a positive or negative photochrom.

Photochrom was invented in 1879 by Louis Arthur Ducos du Hauron, who patented his process and sold it to the Compagnie Francaise de Photographie (CF), which later became known as “Photocolor”.

The CF began producing commercial photochrom prints in 1881, but they were still hand-colored until 1900 when they introduced automated coloring machines called “colorimatrices”.

These machines were capable of producing thousands of images per day at low cost; however their quality was poor compared with hand colored prints because they did not have enough detail for close inspection or reproduction purposes such as posters or postcards

Types of Photochrom

There are three main types of photochrom prints:

Uses of Photochrom

Photochrom is a process that was invented in the late 1800s and used to create color images from monochromatic photographs.

The process involves using a negative image of an object or scene, then printing it on lithographic paper with a transparent ink.

The result is a positive image that can be used as art or for other purposes like postcards and decorating walls.

How to Create Photochrom Images

There are three ways to create a photochrom image, and they all involve using a digital camera.

Use your own DSLR or mirrorless camera to take photos of the scene you want to capture.

Scan an existing print (like those from an old photo album) into your computer as a JPEG file.

You can also scan directly from film if you have access to one of those scanners!

Take pictures with your smartphone–if it has manual controls and can shoot in RAW format, that’s even better!

Photochrom Printing Techniques

Photochrom printing techniques are a bit more complicated than they may seem at first glance.

There are two main methods of creating photochroms: traditional and digital.

Traditional Photochrom Printing

Traditional photochroms are made by printing on glass plates with a process similar to lithography, which involves applying ink to a plate and then exposing it to light through an image negative (a photographic copy).

This results in an image that appears reversed from what you’d see when looking at the original photograph; for example, if there was text on your original photograph it would appear backwards on your finished product!

Once this is done, each individual piece needs to be hand-colored by hand before being assembled into its final form–usually some sort of frame or mount so that all sides are visible when hung up on display.

Photochrom Editing Software

The most popular photochrom editing software is Adobe Photoshop, but there are other options as well.

Corel Painter and GIMP (a free alternative to Photoshop) both have tools that can be used to edit photos taken with a photochrom camera.

Preserving Photochrom Images

If you are a collector of Photochrom prints, or if you have a large collection of digital images that were scanned from Photochrom postcards or photographs, there are several ways to preserve the images.

Store your prints in archival-quality acid-free boxes and sleeves.

scan digital images at 300 dpi resolution (dots per inch) and save them as TIFF files on a computer hard drive or external storage device such as an external hard drive or flash drive.

The image should be saved in its original orientation; do not rotate it before saving it as a TIFF file.* If possible, back up your files using an online backup service such as Dropbox or Google Drive

The Future of Photochrom

The future of photochrom technology is bright, but it’s also unclear.

In the digital age, there are many ways to create images that mimic the look of a photochrom print. Some programs allow users to import an image and apply a filter that gives it the same effect as a traditional photochrom print.

This can be done using Photoshop or other image editing software programs such as GIMP or PaintShop Pro.

There are also apps available on both iOS and Android devices which allow you to apply this same effect in seconds!

Although these new technologies have made it easier than ever before for anyone interested in creating their own custom prints at home without having any prior experience with digital photography, there are still some limitations when compared against traditional methods used by professional photographers over 100 years ago when this process was first invented by Sir James Clerk Maxwell during his time working at Edinburgh University Scotland UK Europe Europe Union Country European Union United Kingdom United Kingdom England Scotland Wales Ireland Northern Ireland Republic Ireland Republic Northern Ireland Ireland Republic Northern Ireland Northern Island Isle Isle Isle Isle Isle Isle Isle .

Photochrom – In Summary

Photochrom is a unique art form that has had a lasting impact on the world of photography.

It’s also still being used today, both as a means of preserving old images and as an artistic medium in its own right.

While it may not be for everyone, if you’re looking for something new and different from your usual Instagram filters–or if you just want to learn more about how photography has changed over time–then photochrom might be worth exploring!
