This week I am getting back to just having some plain ole’ Photoshop fun! Recently I ran across an easy and quick technique to turn an image that looks ho-hum into something great! There are times when an image does not look quite right no matter what is tried. That is when I usually open one of Topaz’s (see the sidebar at my Tidbits Blog for website link) creative filters to see if something connects with me – that is usually the fabulous Topaz ReStyle plugin. (See blog links at bottom of post for more info.) But if you do not own ReStyle, this a pretty nifty way to get a somewhat similar result using a Gradient Map Adjustment Layer. The last two examples do not have extreme color changes, but by adjusting the layer opacity, which seems to be critical in getting certain looks, or trying different blend modes, very interesting results can be obtained.
What does a Gradient Map do? Photoshop maps the shadows in an image to the foreground color and the highlights to the background color. It also allows you to add as many colors as you want by using the Gradient Editor while still maintaining some of the photo’s original tonality. For more on using a Gradient Map Adjustment Layer for black and white images, see my blog links at end of post.
Workflow on How to Randomize a Gradient Map
Recently Kelby One placed a link to a short video by Victor Feyes called How to Get Easy Color Grades in a Simple Way that used this technique. Here are the steps used for getting some pretty fantastic quick results:
- Open Gradient Map Adjustment Layer and set the Blend Mode to Color and the Layer Opacity to roughly 50%. Don’t worry about the actual colors in the color swatch.
- Click on the gradient strip to open the Gradient Editor dialog.
- Set the Gradient Type to Noise.
- Set the Roughness somewhere under 15%, usually nearer to 10%.
- Set the Color Mode to HSB or LAB.
- Check Restrict Colors box.
- Click Randomize as many times as you need to get an effect that looks good.
- If the colors are too intense but look good, go out of the dialog and change the layer opacity – less than 50% is best.
That’s it! It is so simple I am not sure why I didn’t try this a long time ago. These settings above are general and there is no reason why the Color Mode cannot be left at RGB, the Roughness setting increased, or Add Transparency checkbox turned on. And all the Color Mode sliders can be adjusted to give a little different result on the image. (See the last image’s screenshot.) Watch the gradient while clicking the Randomize button to see how the different colors are affecting different parts of the image. Once the gradient is applied, in the Gradient Map properties, there is a Reverse button that can give an interesting effect. To save the gradient for reusing, in the Dialog Box click in field to name if you want and click the New button – it appears at the end of the shown gradients. (Note: if the Save… button is clicked, it opens a dialog to save all the presets in one file and not just the new one.)
The image at top was taken at Ravine Gardens State Park in Palatka, Florida (with this rather steep trail that tried to kill me!) and was pretty much a basic shadowy shot. The images I took here have been hard to post-process due to the bright sun and blotchy effect on the bushes and flowers which were in bloom. Therefore this image seemed like a logical choice to try out this Gradient Map technique. Below is a Screenshot showing the original image with only LR settings applied and the Gradient Map and settings used to create the new color look in the top image. The Adjustment Layer was set to Color blend mode and 36% Layer Opacity. (Click on screenshot to see larger in Flicker.)
What the Gradient Map Dialog Box and Sliders Do
The Photoshop Wow Book (from years ago but still one of the best PS books around) is the only good source I could find on how the Gradient Map Dialog Box actually works so the following info is from this book. By checking the Add Transparency box, random transparency is provided – by checking this box “….will probably introduce more variability than you want to cope with” so instead use a layer mask after the Noise gradient is applied. The Noise Gradient ranges are set by moving the sliders on the Color Model bars which will determine the Outside limits of the colors that can appear in your gradient but the gradient will often include a much narrower range of colors. The Wow Book also provides the following definitions: Roughness: a higher amount makes more and sharper color bands and a lower amount has fewer bands and smoother transitions. Restrict Colors is checked so that the gradient will not include any colors too saturated to be printed with CMYK inks. To create a gradient of just gray colors, set the Color Model to HSB and set the Saturation all the way to the left – now only the Brightness tabs will have any effect on the image. I could not get a very good result doing this. The pretty Azalea below was also taken at Ravine Gardens in Palatka, Florida and is another example of this workflow.
Below are the settings used in the photo above – click on image to see larger in Flickr. The blend mode was still set to Color and the Layer Opacity was set to 55% – any higher opacity and the image becomes very yellow.
A different gradient was tried below. A screenshot shows more of a blue toned gradient applied. Used Color blend mode and 42% Layer Opacity. The image is not finished, but it does give a very different pretty result.
This last image of Old St. Andrews in Scotland is an example of combining the two types of Gradient Maps – the first was a Noise Gradient Map (see screenshot for how image looked before applying the Gradient Map Adjustment Layer – click on it to see settings more clearly in Flickr). On top a regular Solid Gradient Type instead of Noise was selected and Blake Rudis’s action and his gray gradient 19 set to Soft Light blend mode at 41% Layer Opacity was added. Blake has a really good video called Advanced Color Toning Made Easy and he gives away the action and 20 gradients so check it out. It’s a very handy action and I use it all the time! This combination seems to bring some very good results in the images. It is not a huge change but definitely an improvement.
Hope you will try this technique. It gives some really nice unusual looks and can really pull the colors of an image together for some needed pizzazz! I am having a lot of fun with it. Have a great week – Spring is almost here!…..Digital Lady Syd

How to Do a Black & White Gradient Map Conversion
This week just another simple technique learned mainly from Blake Rudis on how to create a pretty nice quick black and white image. The rather low key above image is of the Royal Horseguards Hotel, also known as Whitehall, in London taken from the London Eye. I think it has a bit of a Halloween feel to it. It is a good example of using the Gradient Map Adjustment Layer to convert to a black and white photo.
I am sure most of you have heard that a black and white Gradient Map will create a pretty nice black and white image without doing much else. This effect can be improved by using a couple little tricks. Blake Rudis presented the following technique in a recent Creative Live presentation called Post-Processing Workflow for Portraits and Landscapes. To get a good black and white conversion, a good color image is first needed so this is the first step for getting a good result. To create a black and white image, first set set swatches to the default settings of black for foreground and white for background – then clicking on the Gradient Map Adjustment Layer. Often a very nice black and white image usually occurs and many people just use this. For this image, a really almost black blue tone was used instead of the black color by editing the Gradient in the Gradient Editor (click on strip to get editor). Blake’s tip is to add a Hue/Saturation Adjustment Layer underneath the Gradient Map Adjustment Layer. By adjusting the Hue, Saturation and Lightness sliders, a better range of tones can be achieved. By clicking in the image using the Targeted Adjustment Tool in the upper left of panel, individual colors can be adjusted without changing the sliders manually. The bottom strips under the sliders are color range limiting bars (drag the outer triangles together or stretch them apart) and can be adjusted to get some more variation in tonal range. He also suggested trying a Selective Color Adjustment Layer or Black and White Adjustment Layer instead of the Hue/Saturation Adjustment Layer. I found this whole concept to be very flexible and it makes the Gradient Map Adjustment Layer a much better tool for converting to black and white. The image above got the amazing detail by using Topaz (for website see sidebar at my Tidbits Blog) Studio with the Detail plug-in. Then the Gradient Map Adjustment Layer was used for the black and white conversion, and finally a Hue/Saturation Adjustment Layer was added underneath to get the great contrast. If the Gradient Map Adjustment Layer is turned off, a really weird colorized image appears. It is amazing that this works! The last step was adding a slight color effect using the Camera Raw filter’s Split Toning settings of Highlights 194, Saturation 15, Balance -10, Shadows Hue 234, and Saturation 17 – the layer opacity was changed to 62% for the cooler tint.
The above is one of my tiger images taken at the Jacksonville Zoo a while back. First added one of my colorful painted textures placed above the tiger layer and in a mask, the tiger was painted back. After a little clean up, a Gradient Map Adjustment Layer was added on top and a Black and White Adjustment layer was placed underneath it. The Blue Filter was selected in the Preset drop-down to bring out more detail in the tiger. The sliders were adjusted to get just the right contrast. Then several Curves Adjustment Layers were used to target different parts of the image to get the correct effect. Most of the time the last step in black and white images should be adding the tint. The tiger image used a nice subtle warm tint provided by Glyn Dewis for his lion image from a really good video called Take a Picture from Good to Great in 5 Steps. It was set up in Camera Raw as a Split Toning preset: Highlights Hue 23/Saturation 6 and Shadow Hue 41 and Saturation 6. In this case the last step involved adding a slight vignette to the image.

Well that is it for this week. Enjoy this beautiful fall weather we are having!…..Digital Lady Syd
