How to Request Film Scan Preferences


 

There’s more than one way to skin a cat. Okay, that idiom is a little dark, but the point still stands—there is more than one way to scan film! It’s amazing how much variation you can get from the limited controls of a film scanner, which is why adding your scan preferences to your film order is vital if you need to narrow down the particular “look” of your film images.

There’s more to it than just saying “warmer” or “brighter”, though. We are dealing with subjective terms that mean different things to different people; maybe you think “warmer” means more yellow, but someone else thinks “warmer” means more red. Specificity matters when requesting your preferences!

First, you need to know what parameters of an image you can even request preferences for (because not all characteristics can be controlled well by a scanning machine). The first is density of the overall image, or lightness/darkness. We call it density because it refers to how transparent or opaque the physical negative is (more info here).

Another thing that can be controlled in the scanning process is color balance. But don’t confuse this with controlling specific color channels! Film scanners do not have the same capabilities to adjust images as Lightroom and Photoshop, so the scanning technician is pretty limited in their controls and is governed by “the physics of color”.
 


What does that mean? When working with RGB colors (as opposed to physical ink, which is the CMYK color space), opposite hues have an interdependent balance. Yellow depends on blue, red depends on cyan, and magenta depends on green—and to decrease the appearance of one color, we must increase the color it is dependent on. There is no masking or selective color in the scanning process, so these changes in color balance occur across the entire image.
 


A fake tan and a red-faced barfly in one shot? The film scanning technician has to work within the physics of color to get the best results for both skin tones.


What other things do we have very little or just plain poor control over in the scanning process? One is saturation—making colors more intense/vibrant within the film scanner is very tricky. This is mainly because adjusting saturation in the film scanner can make other adjustments, like density and color balance, get really funky. All of a sudden whites look pink or blue, colors get blocky and smooth gradients are lost, etc.

The other is contrast—not to be confused with density (which is the overall lightness or darkness of an image), contrast is the range of difference between lights and darks. Shadows darken at a faster rate than highlights do, and shifting contrast can be unpredictable sometimes. Ultimately, Richard wants you to get the very best version of your image, and trying to adjust saturation and contrast within the scanning process is not the way to do it. Both should be controlled by YOU while you are shooting (more on that here), or refined in post-production.

So, now that you know a bit more about scanner controls, you know that…

When you are considering the look you like, remember to think of how it applies to skin tone. If there is a person in your shot, typically they are the subject of the photo, which is why Richard Photo Lab always prioritizes the appearance of skin tone when scanning film.

Let’s take a look at some real-world examples of how different density requests affect the same image:

There is a ton of information stored in a properly exposed film negative. The lab can scan to show off more details in the shadowy areas or more detail in the highlight areas. Compare the two images above! Note that the one scanned for shadows holds a lot of detail in the back-lit bride and more contrast in the foreground, while the version scanned for highlights has more textures and patterns shown in the walls and window. 

Perceptually, it feels like this is an adjustment in contrast—but that is really an inherited result of the highlights and the shadows shifting at different rates as we adjust the levels of lightness/darkness for highlight details versus shadow details.

Try not to get confused by the terms shadow and highlight when thinking of these requests—it's tough because scanning for shadow actually produces a lighter image, and vice versa.

But wait, there’s more! If you want to take this one step further, you can request to use a pre-existing color profile... What is a color profile? It’s a set of visual guidelines and references that we build personally with a photographer, getting into the nitty gritty of their shooting techniques and fine tuning their style of imagery. While “borrowing” a pre-existing profile does not guarantee your images will look exactly the same as that photographer’s work (because, hey, they are working with different film stocks, lighting conditions, camera settings, eyes, and a myriad of other variables than you), these profiles can be more tuned in to the minutia of a “look” than density and color preferences alone.

Here’s an example of an image scanned using the lab’s best judgement and three of our most popular color profile options:

Once you've been able to experiment with different scan preferences and pre-existing color profiles to really define the look you love, you should really go through the process of creating your own personal, in-depth color profile as part of our Color PAC service! 

How do you indicate your scan preferences on an order? First head to Richard’s Online Film Ordering Site to start your order! Then, in the cart under ORDER OPTIONS, you can write your scan preferences in the SPECIAL INSTRUCTIONS section of your order, or you can opt to use a color profile.
