Placing colored gels over flashes can add interest to many types of images. In January 2012, I took a series of images of Tiffany using gels taped onto a Nikon SB800 flash placed behind her, but pointed towards the wall. I exposed a short series of images using blue, green and red gels. The main light was a single gridded strip light, which illuminated Tiffany from the side so as to not blow out the colored light behind her. Post-processing these images with the Photo Filters in Photoshop yielded some interesting results, which I will share here.
First, let us examine an image as shot, with no adjustments whatsoever. The side light from the strip softbox is very unflattering:
In Lightroom let us apply the "boudoir white balance" I spoke of on my post January 15, 2014 by setting the Temp to 5135 and the Tint to 34. We will also straighten the image, add a bit of Clarity (20) and Vibrance (20) and lighten the Shadows just a bit:
Once in Photoshop, the eyes will be lightened, the skin smoothed, and a vignette will be added:
Now we will add the Cooling (80) Photo Filter set at 100% Density. I did not want all of Tiffany's skin to be bluish, so on the Cooling (80) layer mask, I painted over the skin of her upper body with a large, soft Brush set at 20% opacity. This revealed some of the original retouched image below:
Just for fun, I created a black and white layer in Nik's Silver Efex Pro 2, using the default settings:
Finally, black and white layer's opacity was reduced to 85%. This yielded the interesting "semi black and white" look which was mentioned in blog posts on December 13, 2013 and January 26, 2014:
More interesting variations will be shown in the next few blog posts.
