What Does Film Grain Look Like

By | 09/08/2022

Capture One Pro 8 has introduced a new Film Grain tool. With this tool you can add moving picture grain to your images in an extremely realistic way, giving the same await and feel you meet in prints created from film (you recall film correct?).

You can also use the tool to add texture to the surfaces in your images however you like without having whatever preconceived notion near emulating a moving-picture show “await”.

Mimics the behavior of traditional silver halide films

The film grain options you can employ in Capture One Pro 8 are generated by an algorithm. This process mimics the behavior of different traditional argent halide films and maintains a natural feel rather than simply stamping a mask over the image as some softwares practise.

The Capture I Motion-picture show Grain will add texture to your images while still preserving the earth-shaking particular and structure in the image, just similar motion-picture show does.

You tin can detect the Film Grain tool in the Details Tool tab of Capture One viii.

The Film Grain tool in its default location of the Details Tool Tab. Here the type “Silverish Rich” has been selected with an Impact of 100% and a Granularity of 80%.

There are three different controls for the Moving-picture show Grain tool, Type, Impact and Granularity:

Type: When choosing ‘Type’ y’all are selecting the “technology” of the moving-picture show you want to simulate. The Fine Grain option is non actually a film grain just the standard “grain” that yous may take used in previous versions of Capture One. And then to successfully emulate a film wait you should choose amongst the following methods:

  • Silverish Rich
  • Soft Grain
  • Cubic Grains
  • Tabular Grains
  • Harsh Grain

The Type that yous choose volition change the expect of the grains by having different backdrop applied, which volition change the shape, distribution and size of the grains.

Silver Rich is a very good starting Type when it comes to exploring the Film Grain tool.



Impact:

With the Impact slider yous can determine how strong you would like the outcome of the film grain to prove on your prototype. In a fashion it is like to determining the opacity of the grain. If you desire to simulate existent film you should use maximum Impact of 100%.



Granularity:

With the Granularity slider you determine the amount of grain per pixel. So to simulate a fine grain moving-picture show, use depression values of Granularity between 0 and 30. If you lot want a real strong visible effect, use values upwards to 100%. This adjustment can be thought of similar to the speed of the film used, when comparison the aligning to the use of Film.

Viewing the grains:

The best mode to see the Film Grain effect is to zoom into the paradigm 100%. Only at these resolutions will you see the actual outcome of the adjustment. If you zoom out, for instance, Capture One Pro 8 will simulate the grain look in an approximate manner but exist aware that this is primarily used for you to encounter that grains have been added. You lot should not approximate the film grain aligning when zoomed to “Fit” as the results may not be 100% authentic to your concluding processed file.

For all three images the Type “Silvery Rich” with an Impact of 100 accept been used.

Preserving details:

In the third image above I’ve added a Moving-picture show Grain with relatively strong Impact. Still you lot can easily see all the of import details in the image that are present without the Moving-picture show Grain adjustment.

The Picture realistic look of the Phase One Moving picture Grain

In the silvery halide film process, a single grain would plough black later on the film is developed, should information technology have been exposed to a proper corporeality of lite. This means that the more low-cal a film was exposed to, the more film grains would turn black after developing.

This kind of beliefs can likewise be seen when using the Film Grain tool in Capture One Pro 8. Due of this movie like behavior of the tool yous will see pure blacks and pure whites without Grains and a super realistic tonality in between. Remember, fully exposed grains would be pure black on the negative and thus pure white on the print, and vice versa.

In this image I have clipped the histogram to ensure that I go existent deep blacks and pure whites. The results meant to properly emulate a “moving-picture show” look.

A 100% zoom into the deep black areas of the image. Discover that the clipped deep black appears without Grain. Just as film would.

A 100% zoom into the bright part of the image. Notice that the image goes totally white simulating that all the motion picture grains accept been exposed. Once more, just as nosotros would detect in picture show.

The Picture show Grain in Capture Ane Pro eight will adapt to whatever aligning change you do to your paradigm ensuring beautiful and realistic Film Grain effects.

Grain designed for impress

The Flick Grain tool is designed very cleverly to generate Film Grain that, in print, volition give the aforementioned look whether y’all utilise an paradigm from a high-resolution camera or a low-resolution camera, as long equally you lot print the epitome at the same size. As a outcome a 100% zoom into for instance a 80M pixel Phase One IQ280 paradigm with Film Grain added will await a little different compared to a 100% zoom into for case a Catechism 5DMKII epitome.

Determining the correct Granularity for a print

How visible the grain volition appear in the final printed prototype depends on how large y’all print your image – exactly similar using real moving-picture show. So it is strongly recommended that you lot do some test print at your normal impress sizes with different values of Granularity, but with stock-still Method and Impact.

Once you accept a clear idea of what settings you prefer for different print sizes it’s a skilful idea to create your own Motion picture Grain Presets for example:

  • Medium Grain A3
  • Medium Grain A4
  • Medium Grain A5
Scaling an paradigm with Film Grain:

The film grain in Capture 1 Pro 8 is added to the epitome at the full size of the images. And then if you procedure the image to a size dissimilar from 100% you should exist aware that the grain will be scaled accordingly and thus it volition look dissimilar. As a rule of thumb you should increase the Granularity by approximately xxx points if y’all downsize the image by 50%. This should be followed in guild to achieve the same size grain-look seen at 100% in Capture I.

100 % zoom

Tip802 Img8 full            Size = 100 %                                 Size = 50 %                                   Size = 25 %
Granularity = 30                                   Granularity = 60                           Granularity = xc

The same image is processed to dissimilar sizes using the Pic Grain tool. To achieve the same visual effect of the Picture show Grain when viewed at a 100% zoom rate, I’ve compensated with an extra thirty points of Granularity every time I reduce the image size by 50%.

Adding Grain after retouching in Photoshop

If your workflow commonly involves retouching in Photoshop, y’all tin still employ the Film Grain tool in Capture One Pro viii as it works the same when applied to Tiff and Jpg files. In this case you start processing the RAW file without using the Moving-picture show Grain tool and so add the Film Grain to the resulting Tiff file after you lot accept finished the retouching.

All the best,
