Selective Color on a B&W Image for Impact


Sometimes I like to just have one or two colors in an image for more impact and artistic appeal. There are many ways to do this in just Photoshop itself – some as simple as using a Black and White Adjustment Layer, a Channel Mixer Adjustment Layer (with the Monochrome box checked) or the Hue Saturation Adjustment Layer (with the Saturation slider set to 100), and in the attached layer mask painting back in the areas you want colored. I decided to use some of the wonderful Photoshop plug-ins that are available and all images in my post today are using them. The above uses probably the most powerful black and white plug-in made – Nik’s Silver Efex Pro 2 (SEP2). This image is of the steps up the side of the Keck Telescope on the top of Mauna Kea on the Big Island in Hawaii. I loved the way the stairs made such a striking line against the white of the building and how the deep blue color matched the sky. I could actually imagine climbing up there and looking around and down at the telescope lens! Now that would be a cool shot! Since there were a lot of distracting colors in the image, the decision was made to convert it to a black and white to remove it, but wanted to retain the beautiful blue color. In SEP2 adjustments were made globally to the image using the Neutral preset and then control points were placed strategically on all the blue areas with the SC (Selective Coloration) sliders opened up to 100% to let the color show through. Nik’s Viveza 2 was used to even out the sky and that was about all. Very simple processing for a very simple image.

Here is another image (from the Hawaiian Waikoloa Village on the Big Island in Hawaii) using Nik plug-ins: First Viveza to add contrast and sharpness to several elements in the image; next SEP2 where control points were placed on the lounger and the water where the color was to appear – adjust the SC slider to 100% to get the full color showing up (or set it lower for just a little color as shown in the water area); and finally Color Efex Pro 4 using the Detail Extractor and the Glamour Glow filters (set to an overall effect of 73%). Back in Photoshop a Gaussian Blur layer was added to slightly soften the background – a gradient was applied to a layer mask to do this and the close up tree trunks were painted back in. The original image was way to busy with the full color applied, but with the blue and cool tones applied, it makes for a relaxing image of Hawaii.

The image above was taken while walking to Fisherman’s Wharf for dinner in San Francisco in the winter. I had a really difficult time getting the look I wanted. This image originally had a very  tungsten yellow look that was corrected in Lightroom. I knew it needed a lot of work but I did not want to get rid of it since it represents to me what San Francisco is all about. After trying many different plug-ins and Photoshop tools, this dark foggy image was the winner. It was really cold, windy and damp outside and this is exactly how I remember it. There were two things I had trouble working with – the bright street light and the soft shot from taking the image at night without a tripod. My camera (a Nikon D300) is not the best at night. One other thing that really improved this image was the crop – it took several attempts to get the balance I was looking for.  There was little color in this image to being with, so I already knew it needed to be processed as a black and white image. Therefore, I went back to another of my favorites, Topaz Black and White Effects (see sidebar for website  link at my Tidbits Blog) using the Classic Traditional preset with adjustments. This plug-in is somewhat like SEP2, but does so many different things that it is hard to compare the two. Both are excellent products and I would be lost without either one of them. The windows were painted back in to bring out the soft warm glow feel. The last step added the Fog 1 preset in Topaz Lens Effects to enhance the fog that was already present to some extent, but this could have been painted in using a fog brush on a separate layer and adjusting the layer opacity. Also, I did use Imagenomics Noiseware on this image at the beginning as it had a lot of noise – they just came out with a new version and I am trying out the trial. So far I love it!

My last example is perhaps my favorite since it came out so sharp and clean. Believe it or not, this wonderful little mill sits outside the Big Thunder Mountain Roller Coaster (here’s a pretty lame U-Tube of the ride but it does bring back memories!) at the Magic Kingdom in Disney World, Orlando, Florida. Once again, several attempts were made at processing this image with the red mill being the focal point I wanted in color. I ended up using OnOne’s Perfect Effects (see sidebar for website  link at my Tidbits Blog) to get this terrific look. I keep forgetting how powerful this program can be and yet it created such a low distortion to the image even though there were four filters stacked to get this result: Black & White Grainy Film preset with the mill and center area of the image painted back in to show the color, Photo Filters Tobacco, Glow Black Soft, and Vignette Big Softy. The masking feature in this program is fabulous and it took just a few minutes to mask in the colors I wanted.

Conclusion: As I said, there are many ways this can be done – you do not have to have the plug-ins. I do believe Photoshop’s Black and White Adjustment Layer is quite a powerful tool to turn you images into really beautiful black and whites. Most of the plug-in effects can then be accomplished using Hue Saturation Adjustment Layers or Selective Color Adjustment Layers. Even Curves and Levels Adjustment Layers can add some real interesting colors and contrast to an image. The plug-ins I used here do add a lot more dimension to an image in a very short time to get effects that take longer to do in just Photoshop, so I do recommend you try out any of the ones I mentioned. Experiment around and see what you can get. As you can see, it took me several attempts and I even walked away from an image for a day, to get the results I wanted. The really nice thing is that if an image is just too busy and there is too much color in it, try adding a quick B&W Adjustment Layer to see if converting it to a black and white can calm it down. If so, then try different Photoshop tools or plug-ins to bring back color on where you want the viewer to focus – it can make what appeared to be at first glance a bad picture into a great one!……Digital Lady Syd
