Rodinal is a film developer, the recipe of which was introduced by Agfa in and which has been actively used since then despite the fact that photographic emulsions have undergone changes during this time.
Film Development Chart
It is also worth noting that the formula of Rodinal also underwent some changes, mainly aimed at improving its shelf life. Anyway, Rodinal is based on chemical p-aminophenol. Rodinal is a liquid concentrated one-shot developer that cannot be re-used after processing. This is one of its big advantages as you always have a fresh developer solution just before the development process.
Also, the unused working solution will not keep. And the Rodinal concentrate has a comparatively incredible shelf life — up to several years in an airtight container.
Despite its long history, Rodinal still remains a very popular film developer thanks to its advantages: a High edge sharpness and low veil. Film negatives developed in Rodinal look much sharper than those developed in Kodak D It is believed that the processing with the Rodinal developer results in grainier film negatives.
However, it is a subjective feeling.
In fact, the grain is the same but Rodinal makes it more clearly visible because of its high edge sharpness. At the same time, the film grain it reveals has its signature and recognizable structure with a rather beautiful pattern.
Currently, it can be purchased under various names but their formulas may differ. Earlier it was released under the name Adox Adonal. Fresh concentrates of these developers may have different colors: R09 is usually less transparent and has a more distinct reddish hue, while Rodinal is light-pink and more transparent.
However, both developers get dark-red with some residue over time being opened. It is known that Agfa reformulated the developer to increase its shelf life. But in general Rodinal and R09 are very similar to each other. I have used both and have not noticed any great difference between them. However, the developing time of the two will differ. In my work, I use Fomadon R09 and I give all developing times for this developer.
It is, however, hard to say whether they are exactly the same. I recommend you to use always one of the variants of Rodinal depending on which of them is easier to get, test the developing times and correct them if necessary.In Kodak introduced two new negative format, and Read more about and film.
The film format was originally introduced by Eastman Kodak for its Brownie No. With the popularity of 35mm film became a format for professionals. ISO also specifies the dimensions of film. Unlikethere is no backing paper behind the film itself, just a leader and a trailer. This allows a longer film on the same spool, but as a result there are no printed frame numbers for old cameras that have red window as frame indicator. Moreover, light from the window would fog the film.
Also, since the film alone is thinner than a film with a backing paper, a differently positioned pressure plate may be required to achieve optimal focus.
Some cameras capable of using both and film will have a two-position adjustment of the pressure plate as well as a switch elsewhere to adjust windingwhile others will require different film backs. The only difference is the spool which holds the film, in case of the roll the core of the spool and the end flanges are smaller than that of the roll. The film is a paper-backed rollfilm, 4. Many of the first generation of film cameras were similar folders, and frequently inherited Vest Pocket or VP in their names — for example the Dolly Vest Pocket.
The Kodapak film cartridge is a roll film magazine for 35mm-wide film with a paper backing. It was launched in by Kodak in answer to consumer complaints about the complications involved with loading and unloading roll film cameras. The cartridge simply drops into the camera. Since the cartridge is asymmetric, it cannot be loaded incorrectly.
You close the back, wind, and shoot. The 35mm film format was developed and produced at an experimental scale in Thomas A.Developing 35mm Color Film at Home: Tetenal Colortec C-41 (Snippet 30)
Edison compiled his caveat for the double perforated cine film in the fall ofdescribing it as a double perforated long band passing from one reel to another, driven by two sprocket wheels.
However, it took several years to become a regular Kodak product. The smaller diameter spool and lack of need for a sprocket allowed for much smaller camera designs.
Other paper-backed 35mm film formats have included Bolta and the film Konishiroku produced for the Konilette. The film is even put back into its cartridge and returned to the user after it has been developed.
Because loading film was easy and the small size made format popular very quickly.

To use it, enter the recommended developing time and temp from the Massive Dev Chart into the relevant fields, along with the actual temperature you want to use. Always enter the temperature in decimal format. Be sure that the units Celsius or Fahrenheit are set correctly, then press the Submit button and the modified time will be displayed.
You can also use this calculator to determine the time change if you prefer to use continuous agitation where a time normally relies on intermittent agitation. This is particularly useful if you want to convert standard times for use with a motorised processor eg. Warnings will be displayed if the difference between the original and actual temperature is large, or the final developing time is short.

Your ultimate visual guide to developing your own 35mm or film photos at home. No darkroom or photo lab needed. Film is wonderful. There are few more rewarding things for a photographer than eagerly receiving your work back from the lab or the drug store, only to find that your shots are exactly as you intended them.
Few things, that is, other than the pleasure of developing film yourself. The resurgent popularity of film is undeniable at this point. For photographers already working with film or those looking to take the leap, one of the biggest drawbacks has been dwindling film development resources worldwide. Moreover, learning how to develop film yourself will give you a better understanding of the process behind shooting analog photos. I strongly recommend beginning home developing with black and white film, especially 35mm, as it is dramatically less complicated for beginners and requires less equipment.
Unlike with color developing both C41 and E6in which essentially all color developers work largely the same way, there are a myriad of developers for black and white film, and it can be difficult to decipher which one will work best for you.
There are minimal differences between liquid and powder; powder can be stored for longer periods and you can mix only part of the chemistry together for only as much developer as required. Deciding on which developer you use is largely a matter of personal taste and dependent on what you want out of your photographs. Solvent developers such as ID, D76, Perceptol, Microphen and XTOL, when mixed at stock or a weak dilution, provide fine grain and are forgiving enough to cover a wide range of exposures on a single roll of film.
To complicate things further, most fine-grain developers can be diluted at various strengths to increase sharpness, although this often comes at the cost of grain. Again, this is likely down to personal taste. Diluting provides more working solution for more film, but stock can usually be re-used up to ten times with increased development time.
Working solutions for development: fixer left bottle and developer right bottle. Both ID and D76 are widely regarded as industry standards and are the most accepting of a wide variety of development times and temperatures.
From my own experience, most different types of fixer and stop bath will work similarly. I generally use Ilford Rapid Fixer as instructed on the packaging and have had no problems with this.
There are a few safety precautions you need to take before starting your film development process. If you feel faint, dizzy or otherwise unwell, make sure to take a break or leave the room.
The liquids used in these photographs are for demonstrative purposes, but you should always make sure to use rubber gloves when handling potentially hazardous chemicals. Working solutions of developer and fixer for one roll of 35mm film.
Measure this using your digital thermometer. Measurements for the amount of chemistry required for different film types are usually located on the bottom of the developing tank.
This is so you can twist the agitator, thereby moving the reel with the film inside on the inside through the developer and fixer while ensuring that all parts of the film consistently have access to fresh chemicals.
The center of the developing tank holds the reel in place and connects to the agitator to allow you to agitate the chemistry and ensure that the film constantly receives chemicals. Next, place the tank with film, center, lid, and agitator includedfilm, scissors and bottle opener inside the changing bag and ensure that it is fully zipped up and closed.
The next steps must take place blind inside the closed changing bag so the film is continuously in complete darkness.She thought the pictures were from her vacation, but when she got it developed she was amazed to find that they were of her First Communion, 20 years ago! Found film is finding an old undeveloped roll of film or negatives in a drawer or the attic. These mystery time capsules can potentially have huge sentimental value and memories.
Why does film expire? With color films, there are layers of silver halides with dyes and color masks. Those dyes colors will breakdown and degrade at different rates.
When developed, the color will shift typically towards magenta. Because the silver halides fail too, but at a much slower rate than the dyes causing the contrast to fade. In many cases, this is preferred and authentic to the time, but with our quality scans, these images can be brought back to life with applications like Photoshop or try the photo editing application that likely came with your computer. If you have a Mac, iPhoto is free and gives you the ability to easily adjust photos.
So who do you trust with developing your old and outdated film? Develop your old rolls of film with The Darkroom. We return your negatives too! Something to keep in mind is that many drug stores and retail stores offering film processing services are no longer returning the original negatives after developing and scanning it, giving you low-quality scans on a disk and destroying the negatives.

Kodak recommends using D as a full-strength stock solution. But there is no reason to use it undiluted. It gives a long density range and allows push processing with relatively low fog. Non-solvent developers produce a coarser grain structure but the image will look sharper. It is because there are not many solvents with such dilution to dissolve the edge of the grain. Fresh solution should be prepared just before developing from certain parts of stock and water.
Once Kodak included charts for this dilution. But a few years ago they were removed from its official data. It is very good for processing high contrast scenes. To push it even more I use it undiluted, but do it quite rarely. The key to stable results is strict compliance with the same rules every time you develop the film. Do not modify temperature and agitation until you get stable results with a certain dilution. If you need more or less film density, first try to increase or decrease developing time.
But the more diluted the solution gets, the lower the contrast becomes, and vice versa. By the way, any dilution other than stock can be used only once. This is very convenient. As a result, you always get fresh solution just before developing and you do not need to put the used one back into a separate bottle after the process is over and calculate developing time for the next film, which is absolutely unpredictable. This is another key to stable results.
To remove air bubbles from the film I tap the tank a few times immediately after the developer is poured inside. I have been using the sealed Jobo UniTank tank system for many years. And, of course, this chart reflects my own experience. Also you may refer to the Massive Dev Chart for other films and times.Riots in the streets! So what does this new formula mean to us?
All new tests for new times with all those dilutions and all those films? Kodak claims, no. I did the best I could with home processing to keep every aspect the same. Single notch for the new and two for the old formula. The Tri-X was processed in Dilution H, for 7. The results amazed me; they are exactly the same! If measured from a medicine cup you had to make sure all the product was removed from the sides of the cup with multiple rinses to remove the syrupy product from the sides.
So, what is different? Many are concerned about the shelf life of the new product. This has not changed. For my use I like the changes, it is a little easier to handle and the fact that my negatives look the same as expected is great.
