The time has come to learn new fun things about photography, to explore new techniques, to figure out how some of the fantastic images that others have posted here at Cambridge in Colour were captured and posted. Two years ago, in the original Project 52, my goal was to improve my post processing skills.
This year, although I want to continue that progress, I also want to move into areas that are new to me such as using controlled lighting to model the features of the subject and to explore some ‘what if’ ideas such as, ‘what would my world look like if I were a puppy’? Perhaps a view of a model railroad layout for the perspective of a figurine on the set? Possibly a series of something historical such as lighthouses?
It might even be worthwhile to revisit an old image to see if my current post processing skills could make a significant improvement in an image that was processed when I first started doing digital post processing?
Week 1: Reflections on Stone
Where to begin this project? There are several areas of photography that I am interested in improving. One of them is working with reflections. Reflections can be many things from ghostly apparitions of something that isn’t quite discernible to razor sharp details that are almost indistinguishable from the original source.
For this week’s effort, I am looking for a pattern on pattern view where both the reflective surface and the refection are clearly visible and yet distinctly different in the same visual space. I thought I’d give this kitchen and sun room scene a try.

I am using a technique I will refer to as a 3X3 rendition of the scene. By 3X3, I am referring to how the image is processed. The goal is to be able to get both dynamic exposure range from dark to light and dynamic depth of field from front to back in the same scene.
To accomplish this, a minimum of nine source images are taken using a tripod for support. In this case I was using a Nikon D7100 with a Tokina 11-16mm wide angle lens at 13mm to minimize the number of focus stacked images required to get the desired DoF.
While focusing on the granite foreground surface, three bracketed exposures (images 1, 2, & 3) are shot to get the detail in the shadows under the cabinets and elsewhere, the normal exposure for the room, and expose properly for the scene outside the windows. The process is repeated while focusing on the middle ground cabinets (images 4, 5, & 6), counter top and sink faucet area. Lastly, a third set of bracketed exposure images (images 7, 8, & 9) is taken at close to infinity to get the back wall of the sun room and outdoor scene.

From experimenting I was able to determine that the workflow should first do the focus stack of the underexposed, normal, and overexposed images in Photoshop CS5 to create three sharply focused images, each at a different level of exposure. Once this was completed, I used these three images to blend into the final image using masks and layers.
I opened each set of images, based on exposure, in Adobe Camera Raw, and adjusted mostly the Exposure, Recovery, and Fill Light to get the best looking rendition. This meant trying to get the best of the shadow area in the overexposed set and the best of the scene outside the windows in the underexposed set. All images in each set were synchronized to have the same ACR settings.
To get the best combination of images to work from, I used Photomatix Pro to produce four tonemapped images by selecting the most appropriate Presets for this scene (Default, Photographic, Natural, and Adjusted). These four versions were added to the over, under, and normal exposure images to give seven versions of the scene that could be blended CS5 using masks and layers.

You will note that due to the adjustments made in ACR, you don’t see huge exposure differences at this point in the process. You will note, however, that the detail, particularly in the pendant lights as an example, is based on the original -2EV, 0EV, and +2EV source images before ACR adjustments were made.
Once the best combination of images were merged to suit my taste, I de-skewed and cropped the image. Next, I used a slight bit of vignette and dodge/burn to minimize some of the overly bright reflections.
Although I prefer an image that is less busy, I particularly liked the wood beams in the sun room, the pattern ‘movement’ in the granite, and the colours in the stained glass and elsewhere.
Although I like the additional detail to explore in the image above, I decided to see how the symmetry of a square crop might concentrate attention primarily on the reflection.
This image could be significantly more cheerful if it were not for the dull overcast day, I don’t think the image would stand any more colour saturation.
