hand tinted photos, black and white photos, photo art
How is it possible to decide in advance what tone an important area will have in the final Photograph. It is quite simple if you know that for any area of uniform brightness, a reflected-light meter will recommend an exposure that will render that brightness in the middle gray in the Black and White Photo.
Two areas often metered when calculating exposures this way are skin tones and shadow areas. An exposure for a portrait is often based on the skin tone of the subject. The other area frequently metered as a basis for exposure is the darkest area in which the photographer wants to keep a full sense of texture and detail.
One object that can be metered is the palm of your hand. Another useful substitution reading is from a gray test card, it reflects 18 % of the light falling on it and a white side that reflects 90 % of the light. A gray card is often used to balance the light in a studio setup or when copying an object such as a painting. It is also useful in color photography as a standard against which the color balance of a print can be matched.
With our digital camera all of the above want apply. Most digital cameras are automated and advanced that you simply point and shoot. Choosing your f/stops or apertures are not important in obtaining a quality print or a rendition of any scene. The photographer hands are tied and creativity takes a back seat.
I will never shoot a digital camera due to those restraints and a lack of negative, which I will need to create my Hand Tinted Black and White photo Art. I love to manipulate my fully manual camera to interpret each scene. The unaided eye will give you unlimited freedom to allow you to capture each scene as you like. Roll film will some day return to our main stream because the burden and lack of freedom of our digital cameras. The rules of taking photos the classic way still apply in the Art world. Technology has become a stumbling block for our Art world, but true artist don't need any computer aides.

**I use color film to produce my Hand Tinted Black and White Photos. Color Photographs begins as Black-and-White negatives. Color film consist of three layers of emulsion, each layer basically the same in Black-and-White film, but responding to only one-third of the color spectrum. The top layer responds to Blue light, the middle layer to green light and the bottom layer to red light. When this film is exposed to color light and then developed, the result is a multilayered Black-and-white negative.
**Those who used Kodak for color film in the early 70's remember the old Blue dot flash. Kodak had their film produced on the Blue side of the color spectrum (blue balanced). Kodak had on the top layer of their emulsion more Blue color couplers than other brands. Kodak film responded very well to cool colors. Their film produced very cool colors
**Afga film had their film produced more on the Red side of the color spectrum (red balanced). Afga had on the bottom layer of their emulsion more Red color couplers than other brands. Their film produce very warm and rich colors.
**Fuji film had their film produced more on the Green side of the color spectrum (Green balanced). Fuji had more color couplers on the middle layers than other brands. They produced vivid green colors, cool in nature.
Most Photographers don't understand why they choose a particular brand of film. I choose my film based on my on interpretation of each scene, this allows me to manipulate Zone "B".
** When I Hand Tint my Black and White Photos, I can exploit the mood and feeling of each Photo based on the actual scene. I use Black and White photo paper to create my Photo Art.
I have a color Photo to guide and help in placement of the colors that I apply to each Photo. This give me the freedom to choose each color and areas which I decide to highlight. This is where I implement my "2 Zone Technique" to reveal the often hidden details that you will see only on the color print. This is where the fun begins. Feel free to try for your self the next time you want to create a Black and White Photo try using color film. After all color film is merely Black and White film with two additional layers added to the film emulsion. Have fun, and good Luck.

zone system, photo art, contrast, black and white photos
...
**The Zone system can be used not only to plan exposure and development for a normal-contrast Black and White negative, but also to plan unusually low or high contrast. Metering a scene will reveal the lightest values. A flat negative lacks Zone 0,I,VIII and IX densities will remain soft, luminous, low contrast feeling of the scene. A contrasty negative has limited tonal ranges, with little details. Most tones fall in the Zones 0 and Zone IX. Contrast can be decreased by increasing the exposure and decreasing the development. By doing this you can determine what Zones will be in the middle of the Zone scale.
**I shoot color film versus Black and White film to avoid this Phenomenon. I enlarge my Black and White Photos to reveal and enhance Zone II through Zone VIII. This allows me to Hand Tint each scene according to the actual colors present. The colors are always placed in parts of the scene to highlight areas of interest. This is where the magic begins. I can alter the colors in areas that has little or no color. By manipulating the colors the Photos look surreal, but in reality if you look closely at my Hand Tinted Black and White Photos their are hidden flaws that only you can see if you have the actual color Photo for comparison. This make my Photo Art unique.
**I can take any Black and White negative and create limitless Art from the same scene. The " 2 Zone Technique" that I have created and developed give me freedom that no Computer generated (digital) imagery allows. I know that all the Computer generated Photos will fade with time.
**My Hand Tinted Black and White Photos meets or exceeds Archives Standards.

**The easiest way to control and adjust contrast is to change the contrast grade of Black and White paper-print, a high contrast negative on a low-contrast paper and low contrast negative on a high-contrast paper.
**A film's response to change in development is strong in the areas of greatest exposure (high, bright values) and weak in the areas of little exposure (low, shadow values). This occurs because the developer rapidly reduces the Silver Bromide Crystals that were struck by light in the slightly exposed shadow areas.
**The longer a negative is developed (up to a limit), the greater the Silver density that develops in high values, while the shadow densities remain about the same. Contrast increases as the spread between high value and low value densities increases, and it decreases as the spread decreases. The lenght of time a negative is developed has an important effect on the contrast.
**Changing the development time is simple if you are using Black and White sheet film, since each exposure can be given individual development. With Black and White roll film, changing the contrast grade of the paper is often more practical.
** Understanding the characteristic of Black and White Photo film and Black and White print Paper you can obtain any type of print to suit your needs. I prefer printing in zone IV to zone VII my Black and White Photo Art the Classic way. When I Hand Tint my black and White Photo Art the colors have a tendency to levitate. The colors place properly give the Photo a three dimension effect. This is where the magic begins, knowing what colors and where to tint. Toning brings out the mood of each scene.

fall, focus, tilts, rise
...
**I use my view (6cm X 7cm) camera because it allows me the freedom that lets me capture my visions and imaginations on film. There is no limit on what the view camera can accomplish. The user can manipulate the movements the same way a conductor dictates to his orchestra how to play a passage of music. It is my best asset and I find new ways to invent my Photos.
**Unlike most cameras, which are permanently aligned so that the lens and film are exactly parallel, a view camera can be deliberately unaligned. The view camera can change and control an image due to its movements. Two basic movements are swings and tilts. Swings are movements around the vertical axis of either lens or film, that is, either twisted to the left or right. Tilts are movements around the horizontal axis of the lens or film, that is it is tipped forward or backward.
**The first movements, rise and fall, change the placement of the image on the film by changing the position of the film by changing the position of the film or lens relative to one another. Rise and fall of the back changes the location of the image but does not effect its shape
**Shift is a sideways movements of either the front or the back of the camera. It is exactly the same as rise and fall except the movements takes place from side to side. Image shape does not change with back-shift, but does change slightly with front shift. Shift of the lens affects the spatial relationship of objects because the lens is now viewing them from a different point.
**A front-tilt, does not change distances inside the camera and thus does not affect image size or shape. But it does affect focus by altering the len's focal plane. When the angle between film and lens is changed by tilting the back of the camera, the shape of the object changes considerably and the focus changes some what.
**Swing is a sideways twisting of either the front or the back of the camera around the vertical axis. A back-swing just like a back-tilt moves one part of the film closer to the lens while moving another part farther away. Front-swing, since it involves swiveling the lens to the left or right, skews the focal plane of the lens to one side or another. The general effect of this is to this is to create a sharply defined zone of focus that travels at angle across an object.
**The practical application of the four movements are virtually endless. Some are subtle and complex, particularly when used in combination.

color spectrum, color temperature, kelvin scale, color film
...
**Color films sometimes record colors that the Photographer did not see. When this happens the picture may look wrong, but this is not the fault of the Film. The brain remembers the way things ought to look and automatically compensates for some changes in color.
**There are several different color (film)emulsion are made, each designed for a different balance of Light wavelenghts. The balance of colors in light is measured by a quality know as color temperature. Temperature serves as a guide because the spectrum of wavelenghts emitted by an incandescent light source varies as it heats up. The temperature reading is measured on the Kelvin scale. The way we see colors as warm or cool has no bearing on the actual color.
** Most Films are balanced to match the color temperature of one of three sources-midday sunlight, and two types of artificial light sources. For the most accurate color rendition it is necessary to match the film to the color temperature of the illumination and some times to add a filter as well.
** Colors add temperature to a Picture. They trigger mental associations, golden yellows, and reds appear distinctly warm, white blues and yellowish greens seem cool. But the impressions go beyond mere illusions of temperature. Furthermore, warm colors farther foward, cool colors farther back. You can use this distance effect to increase the illusion of depth within a picture simply by placing warm-colored objects against a cool-colored back ground.

black and white photos, color, wavelenghts, negative
...
The process that creates a picture on a piece of film involves a reaction between light and the sliver bromide crystals spread through the gelatin of the emulsion layer.
A negative is born when millions of exposed silver bromide crystals are converted to Silver metal by the developer.
Silver bromide crystals are light sensitive, they don't respond equally to all wavelenghts of light. Colors are actually different wave-lenghts within the visible part of the electromagnetic spectrum, these wavelenghts must be factored in when making Black-and-White Photos. Different types of Film responds color differently. Orthochromatic film responds well to shorter wavelenghts, toward the violet to yellow end of the spectrum. Panchromatic Film gives more of a natural appearance. This film records most all colors, red through violet. Infra red Film only records visible colors as well as some longer wavelenghts that are not visible. Its' toward the ultra-violet end of the spectrum.
Unless the silver bromide is properly exposed, they will respond variably to shorter wavelenghts, starting at ultra-violet through blue green.

The zone scale at right has ten steps and is based on Ansel Adams's description of zones in his book The negative. Zone 0(zero) relates to the deepest black print value that photographic printing paper can produce. Zone V corresponds to a middle gray, the tone of a standard-gray test card of 18 percent reflectance. Zone IX relates to the lightest possible print value-pure white of the paper base.
The Zone System allows you to previsualize how the tones in any scene will look in a print and to choose either a realistic interpretation or a departure from reality. Using the Classic way to develop and expose your prints, and understanding the Zone System will help you get improved result in the final print stages.
This is why I use Color film to produce my Black and White Prints. Color film reacts to Black and White enlargement paper better than your average Black and White film. Color film records the colors as they appear, and Black and White film records tones, which are directly related to each tone scale. Color film gives greater details and contrast than black and White film.
I use the Zone System in my final print stages. This is where I can dodge and burn my details. My Photos are printed in Zones III to VII, it allows me to Hand Tint my Black and White Print with vivid or soft colors. The shades of gray intensifies the hue and tint of each color.

A Black and White Negative is a reversal of the tones in the original scene. Where the scene is bright, the negative develops many dense, dark grains of silver. These dense areas hold back light from the paper, they prevent the formation of silver in the papers emulsion and so creates a bright area corresponding to the bright area in the scene. Where the scene was dark, the negative is thin or even clear. It passes much light to the paper and dark silver is formed in the emulsion, resulting in a dark area in the print.
Color films take advantage of the fact that nearly all colors can be reproduced by mixing only a few basic or primary colors. Color films are made with three color-sensitive layers, each of which records the wavelenghts of lights in a different third of the color spectrum. Colors negative film is processed to be the opposite in colors and density of the original scene; then it is printed onto a sheet of sensitized paper to make a positive color print.
This is why I shoot color films to Print out my Black and White Photos the Classic way. Color films gives more details in my prints. The colors remain true and the tones are richer. I use the actual color photo as a guide when my Hand Tint my Black and White Prints.

Printmaking is the most exciting aspects of Photography. Black and White Print making lends itself towards a leisurely creation. You can fine tune the image-by enlarging it and altering the tones of White through Black. You can also reduce or increase the contrast between them. Cropping the edges readys the Print for final viewing.
Photo Printing Paper is coated with a light-sensitive emulsion containing crystals of silver atoms combined with bromine or chlorine atoms or both. Light is passed through the negative and onto the paper. After the print is exposed it is placed in a developer where chemical action converts the crystals into a dark metallic silver. Then the Print is place in a stop bath to halt the action of the developer, then fixer, which removes undeveloped and unexposed crystals, and finally it is washed and dried.
All of my Black and White Photos are in the range of zone "IV" through zone "VII". This allows the Hand Tinting to take on it's on Mood. The colors have a tendency to jump from the Paper.
What makes my Black and White Photo Art Unique ? I use only color film to my Print Black and White Photos the Classic way. It gives me a wonderful guide to know the true colors of the scene for future Tinting. With Black and White film you will only have shades of greys for reference.
Color films has more contrast due to the nature of it emulsion. In color film red is red, blue is blue, and yellow is yellow. Black and White Print paper responds well in the toe and shoulder areas. Density becomes more apparent in the shadows zones.
