Mid-Tone Contrast in B&W Portraits


As some of you may know I have been working on the refinement of the black and white conversion using the channel mixer. In this image we will be looking further into enhancing mid-tone contrast for increased clarity and sharpness. The image above is the before and after. Keep reading to learn the technique.


This is the original image straight out of my Canon EOS 5D using the famous 85mm F/1.2L Mk II lens. Even though it is quite slow the images has such clarity and feel that it is my favorite portrait lens. My son Iain was shot at f/11 1/160 at ISO50 using a single Alien Bee B800 with a medium 30x40 softbox camera left and a 2x4 white foamcore reflector camera right.


Next was the conversion to black and white. For skin tones the secret is the red channel. This setting enhances the contrast in the pinks of the skin for further definition. Be careful however since it can often reveal blemishes in the skin that are typically invisible to the naked eye. Play with it some and you will feel like you have X-Ray vision.


High-pass sharpening has become my standard practice over the last month or so. I like it because you can adjust your sharpness over the timeframe of the retouch because it is on it's own seperate overlay layer. Plus you can always run an unsharpen mask pass on it for even more sharpness.


This is my lightpainting/highlight compression pass. I felt the shin was losing some definition so I painted black on a 50% gray layer to bring down the highlights to further compress them to the midtone gray.


For me the shadow/highlight tool (image/adjustments/shadow/highlight...) is the most powerful image toning tool since the levels tool. I love the variety of looks you can get with it. Seen above is the advanced tool set. You really need to do a good bit of experimenting with every image to get the look you are searching for.


This is the image from above minus the shadow/highlight menu.


This is the final image with a film grain overlay and some minor leveles adjustments.


Here we have the final image with all the layers used. Not the highlight compression layer, and the midtone contrast layers... pretty cool.

Building a Ghostly High-Key Image

I have been researching high-key photographs for quite a while. As many may know, I tend to lean more toward the dark side in my imagery so I was especially intrigued by challenging myself to do something that was predominantly white.

According to wikipedia, high-key lighting is a style of lighting for film, television, or photography that aims to reduce the lighting ratio present in the scene. High-key lighting is usually quite homogeneous and free from dark shadows.


In keeping with this as my guiding principal the ratios on this shot are all the same metered from left, front, right, and top. The background was 1 stop down from F14 metered from all the other locations. As seen above, I used 3 lights and a few reflectors to achieve the image. I used a Canon EOS 5D shooting RAW with the 85mmII f/1.2L lens... may favorite for portraits.


This is the original shot straight out of the camera with only minor color balance and exposure corrections made in the Adobe RAW importer.


This shot shows a minor level adjustment to wash out the background just a bit more. In retrospect I probably should have shot the background 1 stop up from everything else.


I love the channel mixer for black and white conversions. It creates such nice smooth texture and tonality based on the RGB values in the shot. Here you can see the numbers I used.


Here you can see the layers used in the construction of the final image. A pretty simple project IMO. It really boils down to starting with a nicely shots image to start with... and good talent that will do as instructed. My goal was to truly highlight the eyes and you can see how I did it with a series of white vignettes and my light painting layer.


And here we have the side-by-side comparison of the original with the final image. Thanks for visiting and please leave comments.

Svetozar's Sister

Svetozar Stefanov is a contributing member over at Fred Miranda and he shot this great image of his sister. It was discussed on the forum at FredMiranda.com that the skin tones were on the orange side.

I focused first on the white balance using the levels tool and the mid tone eyedropper. I just picked a few tones that i though made the skin look a bit more natural and ended up with what you see below. I also did some work with light painting to even out the exposures and further focus the eye on the woman's face by reducing brighter elements in the shot.


This is the before and after comparison.


This is the after shot all by itself.


Here we have a black & white conversion made using the channel mixer... my favorite.


And finally we have a screen capture of all the PhotoShop™ layers used in making the shot. You can see the various layers labeled as to their function in the retouch.

Lightpainted BMW 335i

This was an experiment that I have been wanting to do for a long time. My good friend, fellow photographer and car lover Ken Volpe (see his amazing work at Transposure.com) and I had been discussing a car calendar project for a few years but never could figure out an easy, portable and affordable solution to shoot cars in the style in which was envisioned.

The challenge was to get the look of a large softbox in a studio without the softbox or the studio. In my research I discovered that shooting lighter colored cars (red, yellow, white, etc...) was fairly easy because the lighter colors would radiate light however; when you got dark cars (black, grey, etc...) which I personally prefer, you were left with only reflections.

I did several tests on my Atlas Gray Porsche 996 Turbo and Sparkling Graphite BMW 335i using strobes but none of theses came out the way I had envisioned. So I had to try something else. I had read about lightpainting and actually did a test using a 1,000,000 candle power flash light with interesting result. I was not getting that broad reflective surface I needed for the smooth, flowing reflections.


This is my Porsche 996 Turbo lit using a flashlight. Several exposures were combined to create this image.

While talking about my dilemma with friends and professional gaffers Jaye Kenyon and Jason Maresch, (click here to visit their company High Contrast Lighting) they mentioned using a KinoFlo tube and that got me thinking. The 4-foot tube would perhaps give me the amount of surface area I was looking for if shot over a long exposure. He let me borrow one so I could try some experiements.

With Laura, my wife and son Iain we went out in the driveway at around 8:00 at night... pitch dark this time of year, and we set-up the tripod, plugged in the kino-flo tube and started shooting. The magic exposure numbers were at f/18 for 15 seconds. After 5 or 6 shots I realized that I would need to combine multipe exposures to get the reflective coverage I was looking for.


This is the primary exposure. You can see my blurred image walking behind the vehicle.


This is the secondary exposure where I walked in front of the car. See the cables and balast for the kino-flo.


This is the two exposures above combined. The second is at 50% opacity and screen overlay.


Here's the mask used to paint out the background elements including myself.


Here's the resulting image after the trash matting.


After some additional level adjustment to finalize the background clean-ups.


Here are the photoshop layers.

Eye macro

I love to shoot eyes and once again my son Iain was my model. As a member of http://www.deviantart.com/ I get tons of inspiration from the many talented artists there. This is a shot inspired by the shot found below at this link: http://ketutita.deviantart.com/art/eye-27513785.

This is the inspiration shot.

I placed a medium softbox about 15 inches above Iain who was laying in the ground. I used a f/2.8 100mm Macro on a Canon 5D and shot as closely as possible. In post I did a good bit to enhance the contrast, color and contrast.

Here's my finished shot.
Here's the before and after showing the enhance clarity and contrast.

Fun with gels

Wanted to experiement using my new Sekoniq L-758DR light meter. I felt that doing something clever with gels would be fun and Iain (my son and always willing test subject) is always up for something a bit different.

I started off with a standard 48" roll of paper on a c-stand. Next came an Alien Bee B800 on my overhead light system. Iain picked the gel color and I clamped it on. Then to get a dramatic lighting on the boy to compliment the direction and mood of the shot I placed the main light just under his chin shooting straight up.

I used the L758 to meter and adjust the light rations and took about 8 shots... this one being the best combination of expression and angle.



Here's the final shot. Did the usual retouch job for extra punch.

Portrait Retouching

This is work I did for Russian Photographer Mikhail Parokhadov. This lovely young lady needed retouching to repair minor skin blemishes. I also did a bit of work with lightpainting to enhance shadow detail and even out a few hot spots on the forehead and cheek.
