I swore I would never post a thread with "high key" in the title on FM. It's an open invitation for critical destruction around here. ![]() |

This image is properly termed "a hot white image". This is any image in which the background is "essentially white". It is independent of the foreground. In this case, the principle subject is really a "medium key" image. ![]() MID KEY The term mid key describes an image with normal tone ranges an reflects the average photo: ![]() HIGH KEY The term "high key" describes an image with predominately light tones. The subject principle colours are very light and white (RGB values that approach 255 and virtuall all tones above 128 for the three colours) tones. There are some detail shadows and mid tones. In most cases, the image should have a full set of tones from pure white to pure black, however, the significantly dominant tones are very light.. as below. For a portrait, there should (probably) be darkness in the eyes, eyebrows, parts of the hair, etc. These dark spots attract the viewer's eye and should be considered the visual centre of interest. A high key image is not simply white background with a fair bit or normal or slightly light skin tone or clothing printed lightly. It is actually very difficult to do a good high key rendering of a dark skinned person with black hair. Shooting a light skinned person with blond hair is much easier. Subject choice is very important. Very often, a high key image has a hot white background (as described below). Note that virtually nothing in the sample high key image is blown out - the background is fractionally off-white and there is differential tones from very light to pure black in the lady's body and face. You could also argue that this sample images has maybe too many "slightly dark" tones in the hair to fully qualify as "high key", however this is the best example I have.... high key: ![]() HOT WHITE The term "hot white" refers to the use of a pure white background and is not concerned with the colouration of the main subject. The background should be lit so that it does not obliterate any subject detail due to flare or blooming. The image below is almost correct as a "hot white" sample, however there is some detail in the background lower left part of the image that should be edited out. I could have selected an image in which the background was "perfectly white without texture". The above "high key" image is consider to be "hot white". Often a "high key" image is also "hot white" but not necessarily since the a high key background may have texture. The image below is NOT "high key" because of the extensive display of mid and dark tones. hot white: ![]() If you look at the histograms of the various images, it becomes easier to see that the definitions really describe where the dominant image tones are. The definitions of "key" have both an aesthetic and a technically sound iterpretation. ![]() Of course, better photographers could provide better sample images ...

Okay, just wanted to make sure i didn't make a high key photo w/o knowing. this was a really badly overexposed test shot. I was able to save the details and tones because I shot in raw, but i absolutely loved how it came out. |

Understanding the role of contrast in attracting the attention of a view is far more important than what you label a photograph. A true high-key photo which has a very limited range of tones does a very poor job of leading the viewer to what is most important in the photo. The most effective photos on white backgrounds (i.e. a photo with a high-key background) will be those were the most important center of interests contrast strongly in color and dark tones. ![]() So if a subject is wearing white / light clothing as above, a very effective portrait strategy is to put them against a white background in backlight such as the glare off the Potomac River in the shot above which was taken with a fill flash on a bracket with a diffuser. Not a "high-key" photo, but more accurately a portrait with a high-key background and high-key clothing. Perceptually the goal is to pull the viewer in from the edges of the frame to the face in the middle and and keep them there. On white the hair and eyes will ideally be the darkest things in the photo. Dark hair will attract attention and pull the viewer in towards the face. ![]() But once you get them that far the shape of the face still needs to modeled the same way as on a dark background, with a pattern of highlights on the forehead, top of cheeks and chin mouth. The only difference is that the contrast between the highlights and shadow are far more subtle. ![]() The background "key" sets up the contrast dynamic for the photo which allows brightly lit fronts of faces to attract attention on dark backgrounds and flat saturated lit faces on white ones to attract maximum attention. The reason "middle" key backgrounds are not effective in most situations is because the foreground subjects don't contrast strongly. Check out this perception exercise I created a few years ago to illustrate the role of contrasting tones in composition and eye movement within a photo: LINK For an effective, attention riveting photo on a white background the formula is actually quite simple: 1) Make the intended center of interest the darkest and/or most saturated colors in the photo 2) Make everything less important lighter in tone and more less saturated in color 3) Eliminate any competing dark / colorful distractions from the center of interest. Butterfly is the type of lighting I prefer on white backgrounds because it creates no dark and distracting shadows on the face: ![]() ![]() But a prerequisite for using butterfly is that the subject have a slim symmetrical face as above which looks good in a full-face pose. For an oblique view on white low ratio broad lighting is effective because it makes the far side of the face contrast most strongly with the background and the brightly-lit "broad" side blend in. ![]() Chuck |

This is a very interesting thread, thanks for starting it Todd. Portraiture is not my primary interest though I did attend a portrait class last year. This was a shot from that session with a model. Does this qualify as high-key? Disclaimer: A bit of PP in LR, but that's it, again, not my specialty. ![]() |

This is high key but some I am sure will disagree. |
