1-Introduction – The two different types of photographic knowledge
I approach photography as being a medium requiring two different sets of knowledge: technical and artistic knowledge. In the first part of this 2-part essay, I addressed the technical aspects of the Phase One P45 medium format digital back that I found to be important in my work. In this second essay I am addressing the artistic aspects of this back that I find most relevant in my work.
Most equipment reviews, if not all of them, address the technical aspects of a specific piece of equipment. This is because photographic equipment is seen almost universally as being purely technical. Certainly, the technical qualities of a piece of equipment are very important. However, I do not see equipment as being purely technical. Why? Because equipment, when used with the goal of expressing oneself and of creating fine art images that express an emotional response to the subject photographed, plays an important role in the artistic outcome of the work.
For one, equipment has an inspiring effect on me and I am sure on most photographers. New equipment inspires us to create new photographs because of the new possibilities it offers. But what are those qualities? Many believe that these qualities are purely technical, that new cameras essentially have better technical capabilities. The possibility of creating images of higher resolution than before for example, or sharper images, or making bigger prints from these images and so on.
Again, this is certainly the case and these were some of the reasons why I invested in the P45. But these are not the only reasons. The P45 inspires me because of other factors that are by nature artistic. For example, the expanded dynamic range allows me to create prints with lower contrast –softer prints if you will– a purely artistic consideration since it is not important for me to quantify how much softer, or how much less contrast, these prints exhibit.
The P45 also gives me access to a different color palette than 4×5 films such as Provia or Sensia or than digital cameras such as the Canon 1DsMk2. Again, this is an artistic consideration since here too it is not important for me to quantify precisely how many more colors I get, or to describe the exact technical differences between the color palettes of these different films and sensors.
These are only two of several artistic considerations that I want to address in this essay. In doing so I will blatantly omit mentioning any sort of data, numbers or charts. Instead, I will use an approach and a terminology that is artistic by nature: palette, feel, like and dislike and so on. In many ways my remarks will be opinions rather than facts, something that art and artists have been known to be traditionally guilty of. If you must have hard numbers, you may be disappointed. On the other hand, if you are curious about how one can have an artistic take on a subject that is traditionally addressed from a technical perspective, you will be embarking upon an entertaining journey of discovery.

2 – White Balance
Let us start by addressing white balance. The P45 is very sensitive to being set to the proper white balance. Outdoors, a custom white balance is often necessary because the color of the light changes throughout the day, most noticeably between sunrise, midday, sunset and also during overcast, open shade or reflected light conditions.
Certainly, the P45 does offer pre-set white balance settings: daylight, flash, shade, etc. However, for some reason I find that the colors I get from these presets are not satisfying to me. It is definitely not because they are not accurate. They are accurate. It may be because I have a different artistic taste than the engineers who created these presets. It may also be because I like to set my own white balance settings to match a specific color palette (more on this later on).
As a result I prefer to use custom white balance settings rather than preset white balance settings. With cameras equipped with auto white balance capabilities, this is not much of an issue. I simply select “auto white balance” and let the camera adjust the white balance for each type of light automatically, without any input on my part. Not so with Hasselblad-V cameras. These being mechanical cameras designed for film use, they do not offer the option of auto white balance through the camera.
The closest thing to auto white balance on the P45 mounted on a Hasselblad-V is creating a custom white balance. Because this is a manual process a new white balance must be created for each new lighting situation. Custom white balance settings are achieved through the software on the back. While creating a white balance setting this way is easy, creating a white balance setting outdoors that satisfies my artistic taste when using natural light (the sun) is something of a dark art. This is because sunlight color changes significantly from sunrise to midday to sunset. You go from a very warm color at sunrise to a cool color during midday and back to a warm color at sunset. In addition, shaded areas have a different color balance than directly lit areas and so do areas lit by bounced light because these areas take on the color of the surface they are reflected by.
Of course, white balance can be adjusted during raw conversion but I do like to get close to the white balance I like in the field. While I often say that I am not doing “LCD art,” meaning that how the image looks on the LCD is not overwhelmingly important to me, I do like to have a rough idea of what the color looks like in the field.
The process of creating a new white balance setting is the same regardless of which approach you use: simply select custom white balance in the options menu, point the camera towards the light source or the subject, and take a photograph. A new white balance setting will be automatically created for that light source and selected as the new white balance setting.
You can create a custom white balance by photographing a variety of surfaces. First, you can photograph the scene in front of you and see what you get. Sometimes this works well, sometimes it does not. Second, you can photograph a calibrated surface, such as a grey card or a Whibal (whibal.com). Third, you can photograph through a piece of white frosted plastic or through an Expodisc (expodisc.com). In that case you need to point the lens towards the light source (the sun). At sunrise or sunset, or in reflected light conditions where there is a strong color cast such as in slot canyons, these options do not always work well.
In these instances I found that I can achieve a better white balance photographing a black surface such as my black tripod bag. Don’t ask me why I get a satisfying color balance that way. All I know is that it works for me. Not every time, but often enough to make it a viable solution.
Sometimes achieving a good white balance in the field is not possible. This is not too much of a problem because the white balance can be set perfectly later on in the raw converter, provided that the image was exposed properly. All you need to do is select a preset you like to get a good point of departure, then “tweak” this preset by dragging the sliders carefully until you get the color balance you are looking for. The main drawback is that in the field the image on the LCD screen will be harder to see since poorly color balanced images often exhibit weird colors and color clipping on the LCD.

3 – Tonality and contrast
The tonal separation, tonality range and contrast range of the P45 are very impressive. It is very much like 4×5 in regards to tonal separation but with a low contrast and a high dynamic range.
These three factors are also very different from Canon 1DsMk2 files and not only because of the higher pixel count of the P45. The simplest way I can explain it (remember this is about art and not technical facts) is that there is something about the sensor, or the way the files are recorded by the back, that creates a very unique tonality and contrast quality.
One of the qualities of P45 files is their beautiful contrast. Not too high and not too low, just right. I rarely have to adjust contrast with these, either during or after conversion. Certainly, the Zeiss lenses of the Hasselblad-V system most likely play a role in this look as well, being excellent for contrast and edge definition.
During Raw processing far less work is required than with Canon 1DsMk2 files. The most important aspect of raw processing is achieving a good color balance. As I mentioned previously the P45 is very sensitive to color balancing — it has to have a very good color balance for the files to look their best.
There is also far less need to reduce the amount of black during conversion because the shadows remain open even though there’s a significant amount of black generated during raw conversion. In fact, I rarely have to add or remove black during or after conversion, while I routinely add black to 1DsMk2 files.
4 – Color palette
P45 files also exhibit a larger range of tones in certain colors when compared to 1DsMk2 files. Green is one such color. There is an amazing variety of greens in P45 photographs of foliage, grass or other predominantly green subjects. These variations go from cyan-green, to yellow-green, to magenta-green with pure green thrown in there.
Tonal variety across the color spectrum, as well as variety of tones within a single color, is something very important for my work. I work towards creating the largest variety of tones I can create and I like separating tones within a single color, such as the greens that I just described. With the P45 the colors are beautiful and with foliage leaves have a great three dimensional quality.
The difference is in the number of colors captured and in the nuances between colors. These are subtle but noticeable differences, regardless of print size. They affect the image as a whole. It is very much like 4×5 film versus 35mm film in that respect. The larger film size captures more light and allows a greater separation between colors. In other words, because the film is much larger, adjacent colors are further apart in a 4×5 film photograph than they are on a 35mm film photograph. In turn, this results in an expanded range of colors and tones on 4×5 and in a compression of colors and tones on 35mm film.
With the P45 a similar effect takes place. However, this is not only caused by the larger sensor size. It is also caused by the larger size photosites (the devices that collect light on the sensor). The P45 has a very large sensor, and although the pixel count is high, the photosites are much larger than on, say, a 35mm full frame 21mp sensor.
Essentially, larger photosites gather more light. The larger the photosites, the higher their light-gathering ability. In turn, higher light gathering abilities translate into more colors and finer separation and nuances within a single color and between different colors. Unlike film, where smaller grains of silver give you finer quality, with digital captures larger photosites give you finer quality.
To prove this point let me mention this: I have digital files from one of the first Kodak-Nikon digital cameras, the DCS 560, which was made available back in the early 1990’s. Although I cannot make very large prints from these files, the photosites were so large that the color quality is outstanding even by today’s standards. This was a full frame (24×36mm) sensor, with only 6mp resolution, which means that the photosites were literally gigantic so to speak, definitely much larger than the photosites on today’s 35mm full frame DSLRs since 35mm full frame sensors are now 16 to 21mp.
A higher pixel count is achieved by a reduction in pixel size (and by implication in photosite size) when the sensor size stays the same. Eventually this process leads to an excessive light gathering loss and you have to go up to the next sensor size. This is sort of what is happening with 35mm full frame digital. We are at the point where going up to medium format is necessary if obtaining the largest variation of tonality and color is important for your work. This is one of the main reasons why I moved to a medium format back instead of a 21mp full frame 35mm such as the 1DsMk3.
However, that doesn’t mean that the color or the tonality is “bad” on a 21mp (or larger) 35mm full frame digital cameras. All it means is that there is an advantage to medium format digital in regards to tonality and color variations. There better be, given the huge difference in cost! That is good news in regards to the extra money invested.

Antelope Beam Collage
This photograph is a good example of a purposefully-reduced color palette. I desaturated the colors and reduced the number of colors to create the palette used in this image.
The colors in this slot canyon are naturally very saturated, often veering towards bright oranges, deep reds and occasionally blues. Here I wanted to move away from these more traditional palettes so I purposefully desaturated the entire color range of the image to obtain a palette that consists entirely of beiges and browns. The light shaft was rendered pure white by removing traces of yellow and magenta to provide a solid color counterpoint to the beige tones in the image that the viewer can use as a reference point.
This photograph is a collage of several P45 captures.
5 – Inspiration
Every tool brings with it new possibilities that previous tools somehow did not reveal. It is hard to say why such is the case. After all, the subject is the same. What changes is how we approach this subject through each new tool, each new camera, as well as what we look for once we know what each camera does best.
In the case of the P45 I feel inspired to create images in which details of the landscape –flowers, plants, grasses, rock patterns, etc.—play a prominent role. I feel inspired to do so because the P45 gives me such a wealth of detail when photographing these subjects. The precision of the capture enhances the very small details that are the mainstay of these natural elements. Each time I open a new raw file, I see details that I missed while looking at the subject with the naked eye. Often, the P45 files reveal more details than I saw by myself in the field. I therefore learn about my subject by studying the image. Instead of looking for details I hope will be there, I expect to discover details that I often missed seeing in the field.
In turn this enables me to create images that I have not created before, images whose success depends on having this intricate level of detail, images that depend on detail and color nuances to be successful. In these images the color is particularly important and so is the low contrast and the large dynamic range offered by the P45.
Certainly, there are limiting factors as well. For example, there is the issue of lens resolution and the fact that I would have higher resolution with lenses designed for digital backs. The Hasselblad V lenses were designed to match the resolution of film, and since the P45 has a higher resolution than film they are not sharp enough to make full use of the sensor’s resolution. However, this concern, which is certainly real, is counterbalanced by the issue of inspiration and by the vision afforded by this specific camera. I feel inspired when I work with my V series Hasselblad cameras, regardless whether or not the lenses deliver the sharpest images possible. I see something different when I use them and that is why I decided to work with them again.

I have always enjoyed working with my Hasselblad V system. The things that bothered me when I was using film (besides the limitations of film itself) were the square format and the relatively limiting field of view of the widest V-lenses (38mm). However, the P45 offers solutions here as well, although in an unconventional way. The square format issue is solved by the P45 rectangular format. Certainly, part of the full V-Hasselblad image is lost, but the difficulties of framing with a square viewfinder are gone as well (square compositions are very challenging). The field of view issue is also resolved, this time through my use of stitching multiple frame captures, something that I detail in my previous essay: Phase One P45 Collages.
In passing I want to add that over half of my P45 images are multiple frame captures. At the time I am writing this essay stitching has become a mainstay in my work as well as a source of constant inspiration.
I just don’t see the same things when doing multiple frame compositions compared to using a wider lens. Plus, certain stitched compositions simply cannot be created with a wider lens. The image geometry is just different than what a single capture can give you, regardless of how wide your lens might be.
6 – Conclusion of Part Two: What’s Next
After I started working with the P45 I was asked frequently if working with medium format digital made me feel different. The answer is that when compared to 35mm (or smaller formats) a larger viewfinder and the necessity to work slower usually results in an increased image quality, essentially at the level of the composition. This is true for medium format and this is even more true for 4×5, whether one uses digital or film.
As I mentioned in this essay, it is the expanded color palette and dynamic range that are the most important assets for me when working with the P45. The increased resolution is a bonus but it will not be visible at small print sizes. The tonal and contrast quality however will be visible at all print sizes. This larger tonal and dynamic range brings colors further apart and gives each color a larger dynamic range, furthering the gamut of each color and increasing the range of hues within a single color. It not only gives you richer colors, it also gives you more variation of hues within a single color.
In turn, the larger dynamic range allows you to create softer images while still retaining a certain level of drama in the scenes that you choose to photograph. During film days it was often assumed that drama could only be obtained by creating high contrast images. While a high-contrast sunset scene, say a very dark foreground and a highly saturated sunset sky, is certainly dramatic, drama in photography is not dependent solely upon this type of rendition. Instead, drama is a function of many more elements besides contrast. Drama can be rendered through variation of colors, tones, composition, lighting, natural events and more.
And who says I want drama in each and every photograph? After all, part of the reason for high-contrast film images was that transparency films created high contrast images in the first place. In other words, most sunsets had to be high contrast because one had to make a choice whether to record details in the shadows or in the highlights. Highlight details were most of the time favored, thereby reducing shadows to black or to very dark tones. Not so with digital, not only because the dynamic range is far greater, but also because several images individually exposed for highlight and for shadows can be combined (through HDR or layering) thereby making the available dynamic range virtually unlimited.
At any rate the color of P45 images is rich and, when properly color balanced, sophisticated. I like to compare this color quality to a fine red wine. A wine that is deep and full bodied, an aged wine that has reached a certain level of maturity and sophistication. I like to think of P45 colors as sophisticated color and as mature color. I see the color palette as being richer, more full bodied and more mature, with more variations within a single tone and more luminosity in the image.
Because of this inherent sophistication, this color palette is not so much in need of over-saturation or of excessive contrast increase. Over-saturation and excessive contrast appear to be more necessary with files that contain less data. While this choice clearly hinges as much on the photographer’s taste as on the camera being used, the fact remains that having more data to start with will provide one with more choices.
In turn, this influences the color palette that I use with the P45. I use less saturation and less variation of different hues. Instead I favor a lower saturation level and an increase in the variation of tones within a single hue rather than a wide variation across multiple hues. I also use a softer contrast that let’s the colors “speak” to each other instead of compete with each other for attention. Other palettes are certainly possible. My inspiration simply has gone in this direction so far.
If you enjoyed reading my notes on my use of color and color palettes please know that I am currently working on an essay focused solely on color and color palettes. This essay will be published in the context of my ongoing series on composition. A move to a new home studio over the summer has delayed my writing somewhat but I am now back to my regular publishing schedule.
