[^snp] + +[^technical]: Capturing a speeding race car or timing a bird attacking its prey. +[^cost]: Both financially and in the time to develop and scan/print each photo. +[^snp]: Good ol' spray and pray. + +However, this advantage of film is also the main downside. +While a little cost, both in time and money, makes you reconsider if the photo is really worth +capturing, too expensive and it's impossible to photograph anything. + +One way to reduce this cost is to shoot black and white film. +As a bonus, it also has the effect of improving your photography, even for color photos. +It's easy to fall back unto a colorful sky or vibrate subject to save a photo, +but black and white forces you to look at lighting, shapes, and form to make an image great. + +To make analog photography even cheaper, you can develop black and white film at home. +Plus, its actually fairly easy, as long as you have a little bit of patience. +I have been developing black and white film for over 5 years now, [^1] +and so far have never had a roll of film without pictures! [^mistake] +For an $100 initial investment, it quickly pays for itself, +and produces better results than many industrial scale labs. +<!-- TODO calculate number of film rolls to pay for itself --> + +[^1]: I also just recently attended a film development workshop, so I am confident I have + enough experience to teach you my process. +[^mistake]: I even once opened the back of the camera before rewinding the film by mistake, + and still recovered all but the last two images! + +# Supplies + +0. Roll of black and white film + - Exposed with pictures! +1. Film developer: [Rodinal][devel] + - Most B&W film developers would work, but might have subtle characteristics. + Rodinal is the most common for stand development and has a long shelf life. +2. Fixer: [Ilford Rapid][fixer] + - Any B&W fixer will work, this is a very common one that works well. +3. Development tank: [Paterson][tank] + - The standard tank used by most. Simple but works very well. +4. [Large graduated cylinder][big-cylinder] +5. [Small graduated cylinder][small-cylinder] +6. Film hanger + - Either a purpose built [film hanger][hanger], or a pants hanger. +7. Binder Clip / Clothespin + - Used to weigh down the bottom of your film when drying. +8. Your Nicest Scissors + - Make sure they are clean and sharp. + +[devel]: https://www.bhphotovideo.com/c/product/724200-REG/ +[fixer]: https://www.bhphotovideo.com/c/product/253198-REG/ +[tank]: https://www.bhphotovideo.com/c/product/886586-REG/ +[big-cylinder]: https://www.bhphotovideo.com/c/product/40136-REG/ +[small-cylinder]: https://www.bhphotovideo.com/c/product/40134-REG/ +[hanger]: https://www.bhphotovideo.com/c/product/40128-REG/ + +## Optional + +The above is all you need to get started, +but here are some additional items which might make your life easier. +When I started developing film I did not have any of these and still got great results. + +1. [Dark bag][bag] + - A completely dark room, such as a closet with a towel over the door, can also be used instead. + - Make sure there is no light entering, if you can see any light at all that's too much. +2. [Storage bottle][bottle] + - Collapsible air-tight bottle to store your dilution of fixer to be reused. +3. [Stop bath][stopbath] + - Optionally used to wash film after developing to neutralize all the developer. + - Or just use water. I do not usually use stop bath and have never had a problem. +4. [Photo-flo][photoflo] + - Wetting agent used after final wash to reduce water marks when film is drying. + - Helps especially for film formats larger than 35mm, not necessary for 35mm in my experience. +5. [Film remover][remover] + - A good bottle opener can also be used, or just your hands to pry the film canister apart. +6. [Stirrer][stirrer] + - Handle of wooden spoon also works. +7. [Hypo check][hypocheck] + - Test if fixer is still good. + - Add droplets into fixer, if no white clouds fixer is good to use. +8. Distilled water + - If you have particularly hard water where you live, distilled water is ideal. + - Also helps ensure the water is room temperature, compared to the tap. + +[bag]: https://www.bhphotovideo.com/c/product/1776387-REG/ +[bottle]: https://www.bhphotovideo.com/c/product/1557486-REG +[stopbath]: https://www.bhphotovideo.com/c/product/27775-REG/ +[photoflo]: https://www.bhphotovideo.com/c/product/28195-REG/ +[stirrer]: https://www.bhphotovideo.com/c/product/40303-REG/ +[remover]: https://www.bhphotovideo.com/c/product/1822909-REG/ +[hypocheck]: https://www.bhphotovideo.com/c/product/1362728-REG + +# Steps + +Below are the instructions for a process called stand development, +an alternative method to traditional film development. +It involves using a very small amount of developer highly diluted [^2] and letting it sit mostly +undisturbed for an hour, +instead of the usual method of agitating the developer every minute for 8-15 minutes. +This produces very similar results but works for any film at any ISO +(even if you pushed/pulled it). [^3] +This means you do not need to calculate any dilutions or development times, +and can mix different film types at different ISOs in the same development tank at once. +Stand development leads to a perceived increase the sharpness and larger tonal range, +which comes at the cost of decreasing the contrast. +For traditional development the only thing you need to change is +the development dilution, time, and number of agitations. + +[^2]: Typically 1 to 100 dilution instead of around 1 to 1 or 1 to 4. +[^3]: This works because the small amount of developer that is in contact with the film gets + completely exhausted by the film. + +<!-- TODO stand development toggle --> +<!-- TODO convert to table --> + +## 1. Load film into reel + - Take film out of canister with film remover. + - Must be done in complete darkness. + - Trim film lead. + - Make it straight and easier to load into reel. + - Align the plastic triangle tabs with your thumbs. + - Not to be confused with flat tabs on other side (they feel very similar in the dark). + - Pass film under the tabs until it passes the ball bearings. + - This is by far the most difficult step so practice it a few times on an extra roll of film + in the light until you get the hang of it. + Then, try it with your eyes closed before doing it for real in the dark. + - Twist reel to load film into reel until the end of the film roll is reached. + - Cut film from canister + - Twist a couple more times to load it all into the reel. +## 2. Load film into development tank + - Place reel onto tube. + - Very import as this tube is what keeps light out of the tank. + - Place into development tank. + - Add funnel on top of tube and seal by twisting until clicked in place. + - The development tank is now light tight and can be brought into the light. +## 3. Mix and pour developer + - Add 1 part of developer for 100 part water + - eg 6 ml of developer and 600 ml of water. + - Minimum of 5ml of developer. + - Water should be close to room temperature at 20 ˚C. + - Remember to mix dilution with stirrer. + - Pour developer into tank and close its lid. + - Agitate by slowly rotating and flipping tank for 30 seconds. + - Tap tank firmly on table to remove bubbles. +## 4. Wait 30 mins and agitate developer + - Slowly rotate and flip tank for 30 seconds. + - Tap firmly. +## 5. Wait another 30 mins + - Prepare fixer dilution while waiting. + - Pour out developer. +## 6. Water/stop bath rinse + - Fill tank with cold water or stop bath. + - This is to neutralize the developer to prevent it from developing any part of the film more. + - Agitate by rotating and inverting tank for 30 seconds. + - Remove water/stop bath. + - Stop bath is reusable, don't pour down drain. +## 7. Pour fixer + - Keep fixer in for 5 minutes. + - Agitate for 30 seconds, then 10 seconds every minute. + - Remove fixer. + - Fixer is reusable, don't pour down drain. + - At this point you are safe to open the tank and check your film. + - Your pictures should now be visible! + - If unexposed area is not uniform from edge to edge, + put back in tank and add more fixer for a few minutes longer. +## 8. Water wash + - Fill tank with water, invert 5 times, then empty + - Fill again, invert 10 times, then empty. + - Fill, invert 20 times, then empty. +## 9. Rinse with photo-flo (optional) + - Quick 30 seconds of swishing. +## 10. Hang film to dry + - Use clip to weigh down bottom of film roll to prevent it from curling up. + - Best to hang them in a dust free area such as the bathroom. + +[volmix]: https://www.digitaltruth.com/devchart.php?doc=volmix + +# Conclusion + +After your film finishes drying, you now have your own developed negatives! + +All that is needed now is to scan the negatives or print them with an enlarger. +Stay tuned for the next part where I go over my home made scanning setup using a digital +camera. +I also recently printed my first black and white photos in a darkroom, +so a darkroom tutorial is also in the works. + +Happy shooting!
