Can you reuse developer

Apr 19, 3. Messages: 3, Apr 19, 4. Note that at least in my experience, the paper developer has good capacity but poor keeping properties. I noticed differences in development when doing a few prints, bottling the developer, and doing another print session with it the next day.

Black and white photography eliminates the distraction of colour, which often gets us looking at the shot a little longer, and looking at different elements as well. Black and white photography removes any distraction of color and helps the viewer focus on other aspects of the photo, such as the subject, the textures, shapes and patterns, and the composition.

In General It is almost always better to convert to black and white in post, because you have much more control over the process. If you use the in-camera conversion, you get it the way it converts. If you shoot in color, then you have many different ways in post to convert the image. What colour looks best in black and white photos?

If using darker colours, we suggest black, royal blue, burgundy, or hunter green colour clothing. Earthy colour tones work really well for black and white family photos. Many times black and white helps you develop a different perspective from what you are used to seeing, which nurtures your photographic eye.

In short, convert images to black and white when the light, form, or texture in the scene is more compelling than the hues of the subject matter.

Black and white is a good choice when the color in a photo serves only as a distraction from the message you want the image to convey. Your skin tone is another thing to consider when deciding whether to get a colour tattoo or a black one. Users questions. How many times can you reuse Ilford rapid fixer? How do you dilute a film developer? Can you reuse film developer? The less alkaline most developers are, the less active they are, so a reused developer may be significantly less active than a fresh one.

A few developers, especially unbuffered Kodak D, cycle up and down in pH as they sit on the shelf. Their activity at the peak of their cycle is somewhat different from their activity at the trough. Exhaustion of the developing agents, in the sense of their being used up, is actually quite rare. It normally happens only with very dilute developers containing relatively tiny amounts of developing agent--in which case oxidation may also be a major contributing factor.

Many developers with two developing agents rely on the regeneration of one agent by the other, so one is used up while the other is regenerated. The amount of developer needed for a given area of film is often greatly overestimated. Most of the developer is there in order to make sure that the film is wetted quickly and evenly. The amount that does the actual work is tiny. Fill a 35mm single-reel stainless steel tank with ml of developer; let it soak for 5 minutes, with some agitation; pour it out.

About 25ml at the outside will remain behind, and of this, a good proportion is simply wetting the tank. In that 25ml 0. This is enough to develop the whole film. Because of the dangers inherent in reusing developers, and the unpredictable activity of reused developers, it is a very good idea to develop films "one shot" whenever possible, using dilute developers and throwing them away after a single use. Trabbi, Eastern Hungary. The foliage around this well-decayed Trabant mean that the overall composition is darker than an "average" subject.

This in turn means that the negative is thinner less silver to develop, slower film developer exhaustion while the print is darker more silver to develop, faster paper developer exhaustion. Printing black borders like this also exhausts the paper developer faster. Schultz, All Rights Reserved. Short Stop The vast majority of developers are alkaline: only a very few developing agents will work quickly if at all in an acid environment.

Short stop is a weak acid which neutralizes the alkalinity of the developer. The classic short stop is acetic acid. Make sure you give it the full time though as this is key to the longevity of your negatives. Now the film is developed and fixed you just need to wash it. Leave the tank under running water for minutes.

Alternatively, fill the tank and agitate, inverting the tank 5 times. Empty and refill the tank, this time invert 10 times.

Next, empty and refill, then invert 20 times. Finally, empty the tank. When the film has been through the wash, fill the tank with water and put a couple of drops of wetting agent in. Leave to soak for a minute then hang up to dry. You can use your fingers, chamois leather or squeegees to wipe the excess water from the film before hanging up to dry.

Practice We would definitely recommend getting some exposed film to try the next step out in the light.
