I'm so glad that I used the zone system

And good old Kodachrome 64
This image was made summer of 1981 while I was living in Death Valley.  I drove up to Dante's View a few thousand feet directly above Bad Water, the lowest point in the USA.

I rememver the evening vividly. Yes, it was hot out, well over 100 but oh so gorgeous view.  But I digress.

To make this shot I spot metered the dude on the rock. The closest ridge and the distance.  I knew I wanted detail in both areas so I shot mid point. I love this image looking north into Death Valley, the dude ads scale to how big that place is.

Metering is everything...the gray scale matters

The hardest thing in the world in my not so humble it to shoot "snow".  Even on an overcast day the gray scale covers the gamut from complete black to absolute white.  Ansel Adams was a master at capturing the gray scale with his "Zone System".  It was all an issue of deciding what was the magical 18% gray and metering to ensure he had detail across the board, then developing the negatives to ensure it happened.  The Zone system in short was one where after you shot the film to expose for the shadows and develop for the highlights.

This image was from my archives and dates back to November 1975.  I was then very much into Adams and his zone system.  I metered off an 18% gray card  that came with my Kodak Professional Photographers Photoguide.  I still carry it today to meter off of in extreme situations when I am shooting on film.  (Yes, I still do my own B&W silver work AND I refuse to call it "analog photography" like some hipsters I know).

So what about the world of digital photography?  You can still use the zone system.  You set your ISO on your camera and use manual settings.  The setting will come from the exposure details given to you from a handheld meter focused on a gray card.  Use the recommended exposure settings from that reading and et voila you are working in the zone system in the digital world.  If you are not sure how to set your DSLR on manual, you can always set it to bracket shots 1 stop apart and shoot of the cameras average meter in semi-auto mode.

Enjoy "Ozark Farm". The original was shot on Tri-X, developed in D76.  The negative was scanned to positive with an Epson V600 Photo scanner.  It does click to embiggin.

Mixing chems like a mad scientist and a poem


OK, I finally did it. I found the chemicals I needed in a store in Pasadena. They don't carry the biggest selection and a lot is non-Kodak but they at least they carried my favorite "D-76" developer still. I was mixing like a mad scientist in my kitchen all I needed to do my first roll of B&W in I don't know how many years.

While mixing the chemicals I was rousting through my box of tanks and stuff and found a recipe box full of interesting stuff for developing film as well as this nifty poem that I had copied from somewhere along the line of my meanders. It is as follows:

I take to my darkroom out of affection for others.
There I make friends with the world again.
There I learn to look away, to focus on infinity.
There I play god with film, paper, chemicals and lenses.
There, in the dark, I begin to see.

Not sure why it moved me enough to type up on a 3X5 index card all those years ago when I started the reference kit in a recipe box. Its still appropriate for the digital age to a degree though we likely can remove the part about seeing in the dark, and change it up to somehow include the PC.

All that aside I got myself set up to start shooting and doing my own B&W film again. Opted for the ever faithful Tri-X Professional because I've always loved its visible grain structure and ability to capture stuff in low lighting. I even drug out my ancient, and I do mean ancient 35MM camera that is absent any form of a bell or whistle, even the built in meter died while in storage. No loss as I rarely used it and more heavily relied upon a spot meter which I still have that works quite well.

Man the torpedoes and launch the "Zone System" film photography here I come. Again.

Its all about a true black....and good mid tones


Talk about a hard shot to get right, but I did. This pic of the bridge and mill in Burfordville MO was taken fall of 1977 for my Black and White photography class. It was exercise in the "zone system" as formulated by Ansel Adams...one of my long time hero's for so many reasons.

New Year and outta the 06 funk

Don't know who I should apologize to first, those who follow my blog or myself for putting my photography aside for the last couple of months. Good reason it happened...finished up the remodel of the house. This wasn't a little paint make over, rather ripped out the entire kitchen and new put in, 2 bathrooms gutted and new put in. Ditto the patio. Some pics so you can see what was done:





Finally last night I got to go out and do a bit of shooting. I chose night time streeet photography for a reason. Am off to London and Paris in April and really want to hone this skill. I spent many years doing night work and loved the quality of light so its a circle back to an love for me. Why I had to pick one that was very cold windy I don't know, but I did.


Wandering down Myrtle Avenue during the Family Festival and Old Town Monrovia when I stumbled across the Kettle Korn store front. This place is usually pretty pristine and it makes the most incredible Kettle Korn. The scene caught my eye and I started to shoot.


I knew when I first peered in the window it was something I'd more push towards the impressionist view with after processing. To do that, you still have to have a good exposure and this scene had its challenges. Dipping back into my bag of tricks I knew that the "Zone System" so beautifully designed by Ansel Adams was the way to go to make it work.


The Zone System is a theory that simply helps you break your scene down into blocks or zones of the shades of gray from absolute black to absolute white. It gives a 10 stop range of gray. The zone assumes that the perfect neutral is an 18% gray and from there you base your exposure. You pic the zone within your scene that you want to be 18% gray, meter that area and expose as your meter readout dictates and voila the area you wanted is perfectly exposed.


The problem with this theory is you have to carefully chose what you want to be the 18% gray. Of course you better know the contrast range your capture media can record. Regardless if it is film or digital sensors each has a range it can effectively capture. If you aren't sure find your self a preprinted (Kodak used to make a great one) gray scale zoned on one side and neutral 18% on the other and take some test shots. Knowing your media limitations help you get closer to the "right" exposure for the gray scale representation you want in the final image.


Back to the problem of picking the wrong gray for your metering for 18% gray. Chose an area that is too dark you have great shadow detail but leaves your highlights completely white and lacking detail. Chose an area too light for your metering gives you great highlight details with no shadow detail. Finding the balance is where the artistry comes in. Bracketing helps you with a range of exposures around what the meter recommended to get the final result you wanted.


Now on to todays image. "Kettle Korn" was an interesting challenge. The front of this store was not lit while the back was strongly lit. There was little light from the street leaking onto the front so I had to work with backlit dark objects and a white wall in the back. A stroke of luck was the fake slate floor was there and knew it was likely a zone V or VI, metered that, used the base "f-stop" down 2 stops and shot with 1/2 stop brackets from that starting point from 1 1/2 stops eitherside of the adjusted. Make sense, it did to me at the time. The 1/2 stop under the adjusted wound up giving me the balance between shadow detail and highlight I wanted to portray. Of course I still had a little of balance work to do with Photoshop to fine tune it for the final image that I ran through the "dry brush" filter for the final image I wanted.


So there you go, even digital art you need to know your capture tool and its strengths and limitations. Bracketing helps get you closer to the ideal you envisioned when you saw the scene, digital makes that cheaper. Enjoy Kettle Korn and forgive the long silence...
