Saturation Is An Essential Key To The Success Of Your Images

One of the most distinctive features of a visual artist’s use of color is their use of saturation. When you think of Ansel Adams’ photographs you think of neutral images rather than highly saturated ones. When you think of Matisse’s paintings you think of supersaturated images rather than neutral ones. Think of your use of saturation as an essential element that will help you define your own signature style.

One of three elements of color (luminosity, hue, and saturation), saturation can give your images specific qualities of energy and light. Here are five things you can do with saturation: one, increase energy and impact; two, add complexity by revealing hidden hues; three, restore life to listless hues; four, calm colors that are distracting; or five, produce softer semi-neutral and pastel palettes.

Read more about Saturation here.

Together, Adobe Lightroom and Photoshop offer an impressive, almost overwhelming, array of possibilities for controlling saturation. Do three things before you choose a tool to adjust saturation with. First, understand and develop your eye for saturation. Second, adopt a consistent strategy for exploring the possibilities it offers your images. Third, understand the differences between the tools, both how they function and the effects they produce.

Know What To Look For

Knowing what to look for will help you choose a direction, a tool, and how far to go with it. It will also help you evaluate the results you produce – and quite possibly improve them further.

Constellation_XXVI_Shadows

One of the keys to making a great print is great shadow detail.

Shadow detail is something to be mindful of during exposure, processing, and printing. Curiously, even if you see shadow detail in your file on a calibrated monitor you may not see all of the details in your print. What can you do about this? Many things!

First Check Your Color Management

Before you start editing your files based on your proofs, check your color management system.

Recalibrate Your Monitor

Make sure you’ve calibrated your monitor with hardware. Set a brightness value of 90-100 lux, instead of using the default brightness target of 120 lux. If you monitor is too bright, your prints will look dark overall, especially in your shadows.

Read more on Profiling Your Monitor here.

Give Your Prints Enough Time To Dry

Inkjet prints come out of the printer almost dry, but not quite fully dry. When they’re fully dry, they’ll appear slightly lighter, especially in the shadows where there’s a lot of ink. So before you evaluate prints critically, give them a few minutes to dry. This affects absorbent matte surfaces even more than glossy surfaces.

Find my resource on Outgassing here.

Look At Your Prints In Good Light

Look at your prints in good light. You need the right amount of light (a CRI of 90 or higher), you need the right color temperature light (5000K is the standard but many viewers prefer the warmer 3600K), and it helps to use full-spectrum light (Many manufacturers now make full spectrum bulbs.)

Media Type sets the amount of ink that's used.

Set Your Media Type Correctly

Your printer driver will allow you to set your media type, which controls ink the amount of ink that is sprayed on your paper. Use too much ink and you’ll lose shadow detail. Use too little and your blacks and midtones will appear weak. If you’re using a paper not made by the manufacturer, choose the nearest media type and then adjust its settings with the printer driver’s advanced utilities. (You’ll find this under Advanced Media Control with Epson printers.)

Print test patches to determine when maximum black is achieved and when separation is lost.

Print A Target To Determine How Much To Lighten Shadows

Before you adjust your files for printing precisely determine how much you need to lighten your deep shadows by printing a target. While they vary a little, most media settings lose shadow detail around a value of 96% on a grayscale. If you print patches of values between 100% and 90% you’ll see exactly where you lose shadow detail. Printed results will vary slightly with each different media setting, so you’ll need to adjust files slightly differently for different media.

Curves does what other color adjustment tools can’t, precisely adjusting two out of three elements of color (luminosity and hue but not saturation) based on lightness. No other color adjustment tool is as powerful or precise as Curves. Surprisingly, many people don’t use Curves because they find its interface confusing. Yet it’s that interface which offers so much control. You can master Curves quickly and easily with this guide. You’ll be thrilled when you do.

Why Use Curves ?

Curves gives you the most precise control of luminosity. This applies to the whole image and to select areas of an image. This can also be extended to adjusting hue by luminance values.

Curves will help you control and refine masks.

Curves will simplify your Photoshop toolset; you’ll need only a few other color adjustment tools.

You can do more with this one tool than you can with any other.

If you asked me to throw away all of the tools in Photoshop or Camera Raw and use only one tool it would be Curves. It’s that good. It’s that important. I strongly recommend that you not only learn to use Curves but that you master it.
