Use the lowest ISO film for the least amount of grain ISO 100. What does this mean? This means if you want to see less grain in your prints use the lowest ISO possible. However, if you need to use a higher ISO film, 400, 800, 1600 etc then you will need to start adding artificial light to your scenes especially if you are relying on the sun. You will need to plan accordingly for outdoor shooting using the sun or indoor shooting using artificial light. Light is your friend when working with film. And don’t forget your light meter.

Generally, the lower the ISO or ASA rating of the film, the less grain it will produce. For example, a 100 ISO film will have finer grain than a 400 ISO film, and a 400 ISO film will have finer grain than a 1600 ISO film.

Selecting a film with a finer grain structure can help one minimize graininess in your images. Films with lower ISO ratings typically have finer grains, so opt for ISO 100 or lower for smoother results and very sharp images

Lo mejor es utilizar una baja sensibilidad de ISO. Utilizar la cámara en Manual. Practicar el pulso, invertir en camaras que te permitan utilizar ISO alto sin romper la imagen.

Using as low as ISO as possible is good but if you are in a situation where there is low light and have to use a high ISO then try over-exposing the image. Over-exposure reduces grain considerably. This is of course, if you are not using additional artificial lighting. But the whole point of choosing higher ISO films are for the lovely grain. Films like the Kodak Tri-X 400 have beautiful grain which can actually enhance the image. If you don't want grain, use low ISO films.

I disagree with the over-exposure increasing grain part. Grain is mainly caused due to lack of light hitting the sensor at higher ISOs. If the sensor gets enough or more light even at higher ISOs grain is reduced drastically. This will come at the expense of losing detail in the over-exposed parts so one has to choose wisely as to what output one needs.

Ensuring proper exposure is crucial for minimizing grain in film photography. Overexposed or underexposed images can accentuate graininess, so use a light meter or the camera's built-in meter to achieve accurate exposure for your images.

Proper exposure is key. Underexposed film will have more noticeable grain when you try to recover detail in shadows during development or scanning. Overexposure can also lead to increased grain with loss of detail in highlights. Use a light meter or your camera's built-in meter to ensure proper exposure.

In two stages—film development and print development. Monochrome film development used three solutions, developer which converted the exposed silver halides into metal silver, stop bath to stop the action of the developer and fix which dissolved the remaining silver halide. It was then washed to remove any remaining fix, which would eventually bleach the image. Finally, it was dipped into a wetting agent which reduced the droplets of water into a fine layer and dried. Colour C-41 negatives were processed in a similar way, with a bleach-fix as the third step. Chromogenic monochrome films were processed in exactly the same way as colour negatives

The development process can significantly impact the graininess of your images. Pay attention to developing times, temperature, and agitation techniques to achieve optimal results. Consider using fine-grain developers or techniques to reduce grain further.

While there's limited control here, some developers can affect grain. Ask your developer about options that might minimize grain for your chosen film.

When digitizing your film negatives or prints, scan them at high resolutions to preserve detail and minimize the appearance of grain. Higher resolutions provide more information for post-processing, allowing for grain reduction without sacrificing image quality.

Avoir un bon scanner afin de traiter les clichés comme vous le souhaitez. Même si le scan reste tout de même très personnel, gardez en tête qu'il y a des références de colorimétrie pour chaque émulsion.

Higher resolution scans will capture more detail, including grain. Consider a slightly lower resolution scan for a smoother look, but be aware this also reduces overall image detail.

Photoshop: limited and it would take a long steps to get some how good results, I stopped using it for noise reduction long ago. Lightroom: light room can reduce good amount of noise in such easy and fast way. but still limited (if you decide to use it follow this equation for best results: sharpen or noise reduction= 100, this means if you sharpen your photo say 30 then don't exceed 70 for noise reduction) Define 2 Nik collection by google: this is for sure the best plug in you can use for noise reduction, it is free, easy to use, easy to understand, have a lot of controls to help you get the best ever results in 95%

The development process can significantly impact the graininess of your images. Pay attention to developing times, temperature, softwares and agitation techniques to achieve optimal results. Consider using fine-grain developers or techniques to reduce grain further.

Encore une fois la retouche reste très personnelle. Vous pouvez utiliser des logiciels de la suite Adobe tels que Lightroom ou Photoshop. Vous pouvez également faire confiance à votre labo si celui-ci se rapproche de votre style d'édition.

Software like Photoshop, Lightroom, or GIMP offer noise reduction tools. These can be effective, but be careful not to overdo it as you can lose detail and introduce a waxy appearance.

Consider the lighting conditions when shooting, as low light can increase grain. Use a tripod to ensure stability, especially in low-light situations, reducing the need for higher ISO films that are more prone to grain. Experiment with different film stocks and developers to find the combination that yields the least grain for your specific needs. Also, consider professional lab development for consistent and high-quality results, and educate yourself on the characteristics of different film types to choose the best one for your project.

ISO, by itself, is not the issue ... the issue is gathering more light. For a given camera/lens combination, exposing for lower ISO increases the amount of light captured. You can get the same effect by using a larger format camera with a larger aperture lens (even if the f/number is larger, or the ISO higher). The point is simple -- capture more light! Once you've captured the image, the only thing left to do is use software designed to filter noise from your images In recent years, software tools (such as the builtin noise filters in Adobe Lightroom and other image processing software have become quite effective for light to moderate amounts of noise. But there will be a smearing of fine detail and an overly smooth,.
