A Philosophy of Photographic Lighting for the Human Face

I spent a couple days with some friends of mine working on lighting setups for interview situations. My friends are into movie making and anything to do with cameras and lenses is of interest to me. I wanted to take some time to write down some of the things I learned while playing the setups.

The first and most important observation was that the purpose of lighting is to bring out lines and features of a persons face. The key features of the face to look at when balancing the light are the nose, the jaw line, and the line that starts at the cheekbones and falls down to the chin, and also the brow and eye sockets. You want those lines to stand out distinctly. When those features aren’t noticeable, the face tends to look flat and sometimes fat.

To bring out those characteristics, you use shadow and highlight, placing lights at angles that will cast shadow to emphasize to hide features of the face. To do this, you will often use three basic kinds of lights.

The key light is the main light light source and is also used to determine which direction you want the shadows cast and to provide the point of light in the eyes that prevents them from looking dark or empty.

The fill lights only purpose is soften the shadows cast by the key light, and fill lighting can be accomplished more often easily by using a bounce card than another lamp.

The last light is the backlight, which is used to highlight the edges of the hair and shoulders, and sometimes to cast light onto the sides of the face to create a starker line on the cheekbones and temple.

Some other observations had to do with atmosphere. Darker lighting combined with soft lighting adds a feeling of closeness. A brighter more even lighting scheme indicates more distance. The color of light you choose helps convey emotion as well, the warmer tones are more intimate, cooler tones are sharper more technical or business like.

These observations are generalizations of course. 

Pectus Update: I Hate Sleeping On My Back

I’m lacking in photo’s to post, due in large part to a serious lack of time during good photographing hours to take pictures because I’m busy getting ready to leave the country, taking care of details that accumulated while in the hospital, and dealing with church business (something I rather enjoy).

Why am I starting off a post about my Pectus Surgery like this? Well, *shrug*, because I’m in a rambling mood. And I feel guilty for breaking my promise to post photos every day. Oh well, there must be content, and Sean wants to know how things are going, and because the rest of the world is probably curious, or at least some of you are because I’m getting search engine referrals for my previous two pectus articles (Pop Goes the Sternum! or How I Had My Pectus Excavatum Corrected, the Aftermath and The Pectus Journey: Before and After (photos)), I thought posting the update here would be a good place.

So, two paragraphs in and I’m finally getting to the point. ;) It has been approximately 4.5 weeks since my surgery. I mentioned earlier that I acquired a cough the week I got out of the hospital, the cough being the sickness of choice this winter, the one going around. I still have said cough, though it does seem to be clearing up, though not quickly. It is possible the reason for that is in part due to my surgery, simply because anesthesia and major trauma have a tendency to put a damper on the immune system, and mine was not real healthy to begin with.

Now for some vital statistics, I still can’t sleep comfortably on my sides. This is more of a mental aggravation than a physical one. I sleep most comfortably on my side, and sleeping has been difficult because the only safe position for me is on my back.

Speaking of which, my back is killing me. You see, when they insert the half inch steel bar beneath your rib cage, they make a two inch incision just beneath your pectoral muscles (that is, they do this if they are performing the Nuss procedure). It just so happens that the 6th nerve running from your spinal cord around the rib cage to the sternum is positioned just beneath the pectoral muscle. It also happens that the 6th nerve starts just in the middle of your shoulder blade.

Getting back to my back, trust me, this is going somewhere. So this nerve is in a bad place. Now, the incision on the right side is longer than the left because that incision is where they insert the bar, and because the right side is where the three inch cross bar is inserted to anchor the bar and to prevent it from flipping. The right side of the chest therefore undergoes a lot more trauma than the left, and because of the cross bar and larger incision, the 6th nerve that runs right in the middle of all this mess gets highly aggravated.

Speaking of aggravated, that is just what happened to the muscle that runs behind my right shoulder blade and on down to about the middle of my back. Very aggravated. You see, since my surgery that muscle has been knotted. Last Tuesday I did something to make it angrier than it already was, and I woke up Wednesday unable to bend much in any direction without severe pain shooting around that nerve causing the nerve endings to communicate a feeling that I would describe as someone taking a sharp object and stabbing my in my sternum. ;)

After much pain medication and a lot of pain, I managed to stretch the offending muscle out enough to get it back to normal levels of pain and knottiness. I expect that when the incisions heal completely, and the scar tissue that forms around the bar to hold it in place is finished growing, the muscle will unbind completely. Till then, I have trouble sitting. Standing is ok, walking is better, but nothing feels as good as lying flat on my back. A position I was in most of last Thursday and Friday, because I spent the whole of both days working that way with my laptop on my knees, unable to sit up for more than a few minutes before succumbing to pain.

Today was a much better day though. I woke up feeling pretty good. The muscle in my back was looser than it has been since surgery, and the pectoral muscles around the incision were feeling very good. I am, for the most part, off the Percocet, though I still take it sporadically when I do something to offend the tenderer parts of my physiology. I find that two pills make me pleasantly drowsy, though not enough to make me sleep without consent. I’m actually much sharper mentally when on the drug, partly I think, because the narcotic loosens me up, much like caffeine does when it causes the release of dopamine and adrenaline. One pill is hardly noticeable.

Other observations: the cough has made breathing difficult. I thing the cough is more the culprit than anything else. I will note that the bar is more restrictive than I had anticipated. I expect I won’t be able to breathe quite as deep or as easily till the bar is removed. This won’t affect my health, and isn’t a concern for me, as I consider the restriction temporary. I can say that aside from the breathing difficulties due to the cough, I do feel better.

It used to be that every day, walking, sitting or sleeping, there was a constant heavy, slightly painful feeling that resided in my solar plexus, just beneath my sternum. That heavy feeling is gone. Also, my ribs beneath my pectus are starting to bend back down like normal. Usually, they stuck out, forming the other half of the bowl. Its good for morale to see my chest starting to look normal, and to be able to look in a mirror and see the torso of a well formed masculine physique. I jest of course. … Well, not really. ;)

I’ll leave you with a few thoughts about travelling. I’m going to Ireland in a couple weeks, where I will be taking a lot of photos, getting to see castles, cliffs, and ancient ruins. I’m dreading the 13 hours of flying and waiting in airports. I’m hoping the next week and a half will see a decent amount of improvement in my stamina and back. Currently, I hit a pretty big wall of fatigue about 2:00 to 4:00 in the afternoon. Walking isn’t much of a problem, but carrying anything substantial is hard, and walking up hill brings me out of breath much faster than I am used to. This is mostly due to this blasted cough, so if you will pray that I may be better by my trip, I would be grateful. I don’t want the flights to be excruciating, so more strength in my back would also be a great boon.

Ok, a long enough post. I promise that I will resume a normal flow of photos, the occasional poem, and hopefully will continue posting writing soon. I am getting caught up with things, and am looking forward to a delightful spring and a long summer filled with not much of anything beyond my normal pursuits.

Thanks for listening,
 

The Pectus Journey: Before and After (photos)

Finally I have photos for you to see. I also saw the doctor yesterday for my first post-op appointment. Everything looked good and I’ll see him again in two months. He told me I could start jogging again, but I think that is a little ambitious.

In my last post on this subject I left off just after coming home from the hospital. I stayed a week at the Spilgers home because my apartment is bereft of a recliner and sleeping on a bed at that time was a painful experience.

Things were pretty tender the first few days. Getting around was delicate. I couldn’t bend much, and I found that putting my socks on was the most difficult part of getting dressed.

Percocet was a mixed blessing. On the one hand, it did a great job of dulling the pain and making me feel comfortable. On the other, being comfortable put me in just the right kind of mood and things seemed funnier than usual. Laughing was a painful experience. Sneezing was far worse. My first sneeze occured on thursday, and I spent a full 5 minutes recovering from the shock of angry muscle tissue and bone.

I found that I noticed improvement every other day or so. I gained a little bit more range, could bend a little farther, pick up light objects with a little less pain and so on.

I ran a slight fever, about 1 or so degree above normal the first week. That eventually tapered off. On friday I tried sleeping on the couch, propped up by pillows, which worked pretty well.

I came home to my apartment sunday. And stopped taking Percocet during the day on tuesday, using it only at night. I managed to pick up the cough that has been making the rounds here in Saint Louis the week before. Fortunately, Percocet acts as an anti-tussive (cough suppressant), and I didn’t feel it much till I stopped taking the Percocet during the day. I started sleeping flat on my back a couple days ago. Let me tell ya, the human body isn’t designed to rest in a propped up position. Sleeping flat has helped emmensely.

I found that most of the pain I was feeling wasn’t from the incisions directly, but stemmed from the knotted up muscles around the incision. The knots are caused by the trauma from the cut in the muscle they made for the bar. The right side hurts the most because the incision is wider and because there is a 2.5 inch bar that runs perpendicular to the main bar and prevents it from turning and adds extra stability. I finally saw my x-ray’s. The bar is about a 1/5 inch wide and about a 1/4 inch thick.

As of today, approximately 3 weeks after the surgery, I feel pretty good. Still some pain and stiffness, but a lot more mobility than last week. I’m told the majority of the pain and stiffness will be gone in another 3 weeks. If I can rid myself of this cough, I’ll probably feel a lot better.

Ok, now for the photos:

The photos were taken with different cameras, so you’ll notice some difference in framing and focal length, but I think they suffice to show the difference. 

Dr. Guimon Needs Your Prayers

For those of you who know Dr. Guimon and aren’t aware of the current situation, I thought a brief post here might help to spread the word that he needs prayer.

Several weeks ago he had valve replacement surgery to correct a heart problem sustained during cancer treatements when he was a teenager. The sugery was a success, but during his recovery he began having problems with his kidneys and lungs.

As of today what I know is that he has pneumonia in both lungs, and has contracted Adult Respiratory Distress Syndrome (ARDS) which is a very serious problem in the lungs, having to do with air sacs becoming more rigid and fluid building up.

Last night his heart stopped twice for reasons unknown to the dr’s. Right now he is on dialysis. His kidneys are working but no where near what they need to be doing. The hope is that giving him the dialysis several times over the next days will help cleanse his body enough for them to see marked improvement in his health.

Dr. Guimon indicated yesterday that he believes he will live through this, and that he is in God’s will, but he needs your prayers and God’s working on his behalf to see this through.

For those of you who do not know Dr. Guimon, he is the missionary I visited in Uganda earlier this year and also 3 years ago. Dr. Guimon has been building an orphanage and a church in Soroti for the last several years. I’ve known Dr. Guimon for almost ten years. He was a professor at my college when I first attended, and is a member of my church.

Best Regards, 

Update: I recieved news at 11:30pm that Dr. Guimon passed away a few hours ago. Your prayers for his family, especially his wife Debbie and son Matthew are coveted.

Congratualation Daniel and Jennifer Bergey

Two good friends are getting married today. And I have the honor of standing guard and ushering them into their new life together. Daniel has written a few words on his feelings about today, and I wanted to second the emotion, and let them both know I’m excited and honored to know them both and to be a part of their wedding.

Dear Jenn and Daniel, it is my prayer for you both that God will bless you and your new family. As you both learn and cultivate your life together, I pray God will be present at every step, and through your shared experiences, that the love of Christ will dwell in you richly.

All the Best,
