Replicating B&W film types using channel mixer in Photoshop

Many people, just like myself, started off with photography before digital was wide spread. I used to work in a camera shop and remember selling the first digital camera the shop ever sold. It had 1 MP and cost about £500. The 128MB memory card cost almost £100. These days it would only hold about 10 RAW images, 30 jpegs at a push. Back then it was the height of technology, people didn’t seem to care the quality was far worse than if using film, it went on like that for a long time.

Behind the counter were hundreds of rolls of film, Ilford FP4, kodak TRI-X, the super fine grain Agfa Pan 25, Fuji Velvia, etc etc. Those were the days when big decisions had to be made long before the shots would be taken. You couldn’t shoot in RAW like we can these days and change the colour balance to suit, any mistakes in the set-up were permanent.

I shot on Afga Pan 100 or 25, not because I thought it was any better than the others but I was able to get it in large rolls roughly 100 foot in length. I had to go into a pitch black room and manually fill refillable film canisters. I learned first by doing it with my eyes closed on already exposed film. I then had the odd habit of always closing my eyes when doing it for real in the blackened room. For the record I preferred to use Kodak Tri-X for general shooting and Agfa Pan 25 for very fine grained images.

I used a Nikon FE-2 and 50mm F1.8 type E lens. I loved that camera but regrettably sold it when I bought a Fuji S2Pro. I wish I knew where it was now but I’m delighted to see a trend by camera makers for more traditional style camera bodies. Some of the new Fujis are stunning.

As I’ve said before in this site I trained only in Black & White, everything had to be hand printed in a dark room using various red filters to increase contrast. Dark rooms are a lot darker than you see in the movies by the way, though we don’t see many these days. Film had to be hand developed which is an art in my opinion. Timings need to be perfect, unless you’re going for different affects such as pushing the grain.

After a bit of searching I’ve found these settings to best match what results film would have produced. In Adobe Photoshop select channel mixer, set to monochrome and enter the settings as be below. The results are okay and great for getting a starting point for your B&W conversions. If I come across any more I’ll update this list

Rain on week one of my self imposed challenge

Today was a dreary day, The drizzle didn’t stop and all colour had been drained from all it touched. The clouds lacked the will to rise to any great height leaving the land shrouded in a grey mist that seemed to envelope everything.

It was always going to be a tough day getting a decent shot of anything so i had to choose my location carefully. Where else would someone go on a wet September’s day….. the beach of course.

I’ve set myself a target of shooting and posting a series of photographs each week. The idea is I will have a target set and a requirement to bring the camera along everywhere I go in case I miss out on an opportunity. I need to get back into photography, hopefully this will do the trick. If nothing comes of it at least I should be better at photography than I am now, and that’s not a bad outcome after all.

I realised most of us have a camera with us all the time, my phone has an 8MP camera which would have been a top of the range digital camera 10 years ago, and just look at the quality of the work that was being produced back then. My Nikon D200 and Samsung compact will be in a camera bag kept in the car.

So no more excuses not to take pictures.

To give you an idea of the weather today, this is not a black and white photo. The levels were changed in photoshop to give it a more moody look but it’s as grey as it was when taken.


I did manage to get a couple of shots taken before I decided to pack it in, I wasn’t risking the camera as the rain got heavier.
