There are some great mural's down at the waterfront and they are constantly changing. In fact some new ones are going up in the next few days, hence the blank areas here.
How wacky are those clouds though! Result of the long exposures required with slow film, pinhole, and deep RGB filters. Love it! 😍
Wouldn't it be great if this was a real Polaroid and not a Polaroid Lab print. Not a chance though.

Love how the curve of the tidal pool leads you through to the "giraffes" on the horizon.
Those colours are pure Trichrome magic 😁

This striking image is a full color restoration of a piece from the Prokudin-Gorskii Collection at the U.S. Library of Congress.
Prokudin-Gorski was a Russian photographer working in the early 20th century who employed a revolutionary three-color(RGB) photographic process which allowed for the projection of full-color images through the use of tinted glass plates.
Having come across the LOC's fantastic exhibit of restored Prokudin-Gorskii photos and discovered that the library had made scans of all the P-G images freely available to the public domain, I decided to see if I could match the great results that the LOC's restorers had accomplished using an image that they had not restored themselves.
The resulting image displayed here is a true three-color composite and is NOT hand-tinted. The original three-color separation is provided on the right for comparison.
Here were the steps I used(all in Photoshop CS3):
1. Isolated the three separate images (Blue, Red, Green from top to bottom) and pasted each into separate layers.
2. Used the Auto-Align Layers command for basic layer registration, hand tweaked with Free-Transform.
3. Pasted each registered layer into the appropriate channel in a new layer to create color composite.
4. Used the Levels and Curves commands on each channel to set appropriate black, white, and gray points.
5. Used Healing Brush and Clone Stamp Tools on a per-channel basis to remove scratches and other surface damage.
6. Corrected faded and stained areas (again on a per-channel basis) using Burn and Dodge tools.
7. Corrected overall tone balance and contrast using Curves Adjustment Layer in RGB mode.
8. Used Layer Masks and Hue/Saturation Adjustment Layers to correct remaining color casts.
That's it! - No fancy filters involved.
If you'd like to try your hand at the original image yourself, you can find it by entering "LC-DIG-prok-01657" into the "Searching Numbers" field on the following page:
memory.loc.gov/pp/prokquery.html
Any and all comments are welcome!
UPDATE: The Library of Congress has made some changes to its website, and it sadly seems that the original three color separations are no longer available for download. One can still, however, find raw premerged versions of the images at this link. Simply download the TIFF version of the file from the link and begin at step 4.
UPDATE 2: It looks like the original black and white plates are back up, so the whole process above is once again valid!
Check out this monstrosity.
It's called the Doyen Trichrome 35mm film camera. The plaque mentions a projector, but I didn't see it, unless it was behind this thing, or else it did double duty of first being a camera and then being a projector. Here is what was said about it on the plaque:
"Dr. Eugène Louis Doyen came to prominence for filming surgeries for educational purposes starting in 1898. With the help of his mechanic, Auguste Hulin, Doyen developed a cinematic color process which used three separate filmstrips. Doyen’s system foreshadowed the trichrome Technicolor camera, which also used three 35mm filmstrips. The camera and trichrome projector featured here were never manufactured. They are prototypes found in the collection of Hulin’s descendants."
That's all there was about it. I looked online, doing a Google search and then a Wikipedia search, and I came up with nothing.
In any case, this device was never put into practical use, which is why there was not much else to find about it online.
But, as it said in the description, this device foreshadowed the three-strip Technicolor camera, which I will share a photo about that soon. So it seems the engineering geniuses at Technicolor borrowed heavily from Doyen's invention and then took it several steps further, making it a viable camera to record images on film in color.
But it is interesting to see where the crude, humble beginnings of great technology occurred.

CMYK print, using Jacquard SolarFast dye, on 9x12 watercolor paper, from digital negatives. This was a black and white 6x9 shot with my Moskva 5, AI colorized, converted to CMYK colorspace, split into 4 black and white negatives and printed on OHP transparency film. 12-15 minute exposures in my UV light box.

Taken with a Trilogy 3D1000 camera.
Trichrome photography involves taking three exposures of the same subject on black and white film. Each exposure is taken through a red, green or blue filter. These photos are then combined to produce a colour image. Three separate exposures could be taken with the same camera mounted on a tripod, though this would only be possible for static subjects, a purpose made camera with three lenses allows the 3 exposures to be made simultaneously.
The process was first used by Sergey Prokudin-Gorsky over a hundred years ago, he used projectors with coloured filters to make a combined image, nowadays it can be done with photo editing software such as Photoshop.
For these trichromes, I used a three lens “Trilogy” camera, originally marketed for making lenticular stereo prints. I taped red, green and blue filters in front of the lens, and shot on Ilford Pan 400 black and white negative film.
My latest column in this week's Amateur Photographer magazine. This one is about the Trilogy 3D1000 camera, which was made to produce lenticular stereo prints, but that I used to make trichrome colour images.

I have been asked about my method, I use Photoshop Elements, but a similar method can be used with other image editing software. These are my notes, starting with a scan of the black and white negatives:
open triple image
select first image (blue on the left)
copy
new image from clipboard
increase canvas size by 10% to allow for registration
change mode to RGB
go back to source image and move selection to next frame
copy and paste into new layer of trichrome image
repeat with 3rd (red) frame
you now have an image with 3 layers (blue at the bottom, then green then red)
for each layer, bring up levels dialogue (CTRL + L) and select colour channels, so in the red channel set the OUTPUT levels of the green and blue channels to zero, go back to RGB channel and adjust levels as needed
at the end of this stage the three layers are now coloured red, green and blue (top down)
change the blending mode of the top 2 layers to “Linear Dodge”
next use the nudge function to align the images (align to one area, there will be mismatches between the layers for all but distant views due to parallax between the lenses.
Make any final adjustments to overall levels, saturation, contrast etc
tweak levels of individual layers if needed.

Trichrome photography involves taking three exposures of the same subject on black and white film. Each exposure is taken through a red, green or blue filter. This was taken with an Olympus XA4 camera on Rollei Retro ISO 400 black and white film. This is also an example of the Harris Shutter Effect.
Love it when a plan comes together. I wait for bright days with blue skies and moving clouds. This ratchets the Colour from Movement up to 11. This scene did not disappoint. You never quite know what you are going to get but this one brought it all! 😁

For these trichromes, I used a three lens “Trilogy” camera, originally marketed for making lenticular stereo prints. I taped red, green and blue filters in front of the lens. The film here is expired Fuji Velvia slide film, developed as black and white in Rodinal 1:100 for 60mins semi-stand at 20 degrees.
A more abstract Trichrome image of the Willis Building in Ipswich. Managed to nail the composition framing with the building with the Tree branches and the tree reflections.
I've not seen this colour palette in any of my previous Trichrome images, always a surprise when you pull these together.

Another pinhole trichrome of Felixstowe Docks from Shotley Marina.
Love the reflections of the "giraffes" in the tidal pool.
Those colours are pure Trichrome magic. They come from the long exposure required with pinhole apertures, ISO 125 and 3 stop filters. The movement in the clouds against each filtered exposure induces them 😁

Malaga Trichrome - a colour image from black and white film
This year I'm using a different film format each month, starting with the smallest and working my way up through the sizes. The format for May is 35mm half-frame. I like using half-frame camera to make short sequences of images and collages. This trichrome image was made a few years ago using an Olympus Pen EE3 camera.

Love a bright cloudy day for Trichrome images. My filters are scratched and dusty. Sometimes it bothers me, sometime I love what it adds to the images. It's film, it's pinhole and it's a tricky process. Isn't ever going to be perfect so embrace the chaos! 😁
I got a wild idea to try to recreate Aerochrome using the trichrome method and Rollei Infrared 400 film. These are the results. See the process at youtu.be/KGMQ-W4QtP8

My first outdoor attempt at a #PaperTrichrome #TrichromeParty shot on 8x10. Not exactly a success, but still kind of cool! R,G,B filtered 8x10 ra4 paper negatives developed in b+w paper developer. Scanned and combined in PS. #BelieveInFilm #BelieveInOverlyComplexProcesses
My most absurd #trichrome to date.
I have been thinking about making trichromes with my new 8x10 camera, but film is expensive and most options are ortho only!
BUT it occurred to me that ra4 paper is panchromatic AND can be developed with B+W chems (though w/low dmax). And it works! (low-res cell phone scans edited and combined in PS).

Three B+W negatives shot with color filters were combined to give a color image.
It was a mildly breezy day, with clouds. The gentle sway of the trees between exposures and varying light intensity caused colored shadows. Movement of branches and leaves caused additional colored ghosting. I also moved around in the three photos to make structured ghosts (the blue one is easiest to see in the original size). Note that the stationary smokestack is properly colored only where the light is constant. Moving shadows/light give the rainbow on the left.

Here are more examples exploiting colored ghosting, a technique also known as the Harris shutter effect. Other attempts at color separation photography (trichromy) can be seen here.
Edit: Some have asked why the colors look different with this process than in an image from a common digital camera. The answer derives from the absorption profiles of the color filters used here vs those built into a camera sensor. Spectra for a typical Bayer array on a digital sensor can be compared to the Red 25, Green 58, and Blue 47B that I used. The blue 47B has a much narrower cutoff, excluding green light absorbed in the Bayer filter counterpart, and the red 25 has a longer wavelength cutoff, excluding some of the yellow absorbed by the Bayer filter counterpart. Note that there are several different filter configurations in use on consumer camera sensors, including three color RGB (red, green, blue) used in the example here, CMY (cyan, magenta, yellow), and a four color RGBE (red, green, blue, emerald) design. Each will give a different appearance to an image.
Edit 2
Jorg Piper's paper RGB-Splitting and Multi-Shot Techniques in Digital Photomicrography–Utilization of Astronomic RGB-Filters in True Color Imaging shows dramatic improvement in image quality when using RGB filters on a digital camera (Olympus Camedia C-7070).
