A trip I took with Crosspoint Church, Chino, CA to Bishop, Mammoth and the surrounding regions.

My days were filled with hiking, hot springs, 4x4ing, good food, and excellent fellowship.  And daily reminders that the LORD was all around us, with us, and for us.  An amazing weekend.

The new #PhaseOne#XF  is a welcomed change, but I think they really missed a huge opportunity. They had the chance to finally be a medium format company with more than one AF point... and they didn't do it.

I still think Phase is the superior system to Hasselblad or Pentax, but if you're going to develop and design a system that's probably going to be used for at least the next 5-6 years without change, ensuring it has all the best possible tools is paramount.

I'm no engineer, but surely it can't be so impossible on medium format to develop a better focusing system, can it? I'm not asking for a dSLR-like 40+ AF point system. Frankly even 3 would be a massive improvement (center, far left, far right for portrait shooting, or for having a composition in which objects to the left or right of the frame are highlighted).

This is that golden opportunity for Fuji to develop something better or for Pentax to get Leaf Shutter lenses and develop a program to match CaptureOne. Business is war, if you hold punches, it's a mistake because you can't expect your opponents to do the same. Phase will definitely continue it's dominance for now don't get me wrong, but competitors are creeping up!
The Phase One XF Camera System is built using full-frame Medium Format sensors 2.5 times larger than the ones found in high-end DSLRs.

Paul C Buff 86" Soft Silver PLM Light Tests

This is just to A) show the modifier I've been talking about. And B) give you a size illustration. This thing is massive. Safe to say my arm span fits inside of it.

Some may be disapointed that the opening of the PLM isn't 86". It's measured from one edge, across the arc to the center, and then from the center down the arc to the other edge. Even still, over 7' of material is massive.

This also illustrates the light is pretty even across the front, except near the spokes. This is due to the fact that no fabric material can truly hold a parapolic shape. But it wouldn't be practical or cost effective to have a solid piece of metal or plastic this size. And even if it was cost effective, how in the heck would you transport it?

Paul C Buff 86" Soft Silver PLM Light Tests

In this diptych, the light is directly side lighting me from camera left. Raised up about 8-9' and angled down slightly towards me. Note my shadow goes directly right.

Lit like this, everything appears significantly more contrasty. Note how all the imperfections in the seamless background become immediately visible in this setup. The highlight portion of my face is harsh and quickly falls off into shadow from left to right. No light source no matter the size can 'prevent' this, but that is part of the look that can only be gained from direct sidelighting, at least not from a practical perspective. I suppose in theory the light source could be 50' in diamater and then it would just wrap around everything, but that isn't a useful theoretical discussion.

That said it's easy to create broadlit (left) or shortlit (right) looks by simply repositioning the head. With the body turned towards the light as per both my images it makes the light soft vertically on the torso. With the body turned away from the light, it all will quickly fall into the shadow as literally the body will be blocking the light. This effect is similar to how my face is in shadow on the image in the left.
No retouching was applied to these images. Just a minor contrasts adjustment in curves and a b&w conversion. Also, my sweater still makes me look fat (oh well).

I picked up a new modifier and I'm doing work in preparation for where I want to go next. As such I spent a day doing a series of lighting tests on myself.

The modifier is Paul C Buff's 86" PLM in Soft Silver. I did buy the front cover diffuser as well, but it wasn't used in this particular image.

So this particular test image is testing several things. This was the last image of the day, so I tested 1 thing at a time individually and methodically to start and eventually ended up here. It tests the speed of the Einstein in terms of ability to freeze motion. For non-photographers flash bulbs emit their light at a specific rate. The faster they do this, the greater their ability to freeze motion. This is a different measurement than wattage which is for quantity of light. I guess the car analogy would be: 0-60 time versus horsepower.

Secondly I was testing the lighting position. It's a two light setup with one light camera left with the 86" PLM high above me and pointing down at me at around maybe a 45 degree angle and feathered away, and another light with a 64" PLM camera right 45 degrees from center and pointing horizontally. I wanted to make sure that the shadow density wasn't so high that even in a jumping shot there would be exposure on my face. Not a lot of course, but that is intentional. With this sort of highly dramatic lighting, it's more designed to show form rather than draw attention to the face.

The image doesn't really have any processing. I think I very slightly added mid-range contrast with a curves adjustment and of course a black and white conversion to more clearly show the light and darks and transitions. I didn't retouch myself or the ground (with all its dirt) at all.

I am considering doing a short write-up about the 86" PLM as well as just a general discussion about lighting and design. As always, more to come.

100mm f/2.8L IS Macro - Portrait Test

Elinchrom 39" Deep Octa. 45x45 standard lighting position.

The magnification and sharpness of this lens is phenominal. The crazy part is that the depth of field is so shallow. At f/8.0, the circle of confusion is less than 1ft. It creates very pleasing, shallow depth of field portraits that look natural and classic. Compression is spot on. The long and the short: this lens is sick. I want one in my bag.

No real processing. This is basically straight out of camera. Played with curves very slightly, and did a B&W conversion.

Thanks to +Mark Thiel at Powell Camera for the rental.

Paul C Buff 86" Soft Silver PLM Light Tests

4 images, two lighting positions. All 4 images have a lighting position similar to side lighting. The only difference is that the light is moved closer to the camera. That is to say, the height, distance and angle are all the same. But I simply scooted the light towards camera. It also means that the light isn't directly hitting the subject (feathered light). To help illustrate what I'm saying, the light appears to be hitting in front of me rather than directly on me. Take note of my shadow on the floor. The first two are only angled away slightly. The bottom two are angled away more.

The top two I'm only slightly out of center by a few feet. The bottom two it's increased by a few more feet. Even with this "slight" change the effect and change in look is dramatic. The top two have what is described by photographers as more "crispy" contrast. While observing my face in particular it has a much brighter highlight and a quick falloff into shadow. Pulling the light out further as in the bottom two the transition is much smoother. The highlight isn't as bright, and the shadow portion of my face is more filled in, that is to say there is less shadow.

Neither of these looks are "incorrect". It's more a matter of personal taste and preference. I personally prefer the punchyness of the top two images, but some prefer the softer smoother light of the bottom two. Of course what the client needs or specific artistic intent also comes into play. Sometimes it's appropriate to have a more punchy look, sometimes it's more appropriate to have a softer look. It also illustrates that a small change or move in the light can have a dramatic effect. It also illustrates why so many photographers have such different looks. By finessing the light in small subtle ways, the lighting, and by extension the final image can have a dramatically different apperance.

No real editing done to the image.  Just a slight contrast adjustment in curves and a b&w conversion.

Paul C Buff 86" Soft Silver PLM Light Tests

One of the first test images. This is a standard 45x45 degree light position. In this position most of the face is in light with a relatively smooth transition from highlight to shadow (soft light). The shadow side of the face still has enough to be visible, showing the pleasant wrap in using a large modifier. Because it's uncovered and silver it does still retain some of the aspects of a harder/contrasty light source.

At 86", it's stupid easy to light a full body portrait. The light is broad and even. It does have a bit of a hotspot in the middle as you may be able to see. My hands are probably half to one stop higher than my face. The diffusion cover should fix that 'problem' though. It's a tradeoff however. Uncovered the light is specular, covered it's more even. Pick your poison as they say. Another alternative is to have the hotspot directly on the face and allow the light to falloff towards the feet.

All that said, this is an ideal light source to be used in fashion, editorial, or heck anything that a large soft light source (with some hard source characteristics) is desired.

No real post production done on this image. Just a slight contrast adjustment in curves and a b&w conversion. As a side note, looking at these photos, I'm finding out that my sweater makes me look fat (it's not particularly form fitting). Oh well. I didn't bother to 'liquify' myself to skinny.

Janus
"All the World is a Stage" photo project, part 1 with Nora Ann-Francis Martin-Hall 
- 
In ancient Roman religion and myth, Janus is the god of beginnings and transitions, and thereby of gates, doors, doorways, passages and endings. Usually depicted as having two faces, since Janus looks to the future and to the past.

Photographer of Dreams
Introduction
I just want to create imagery.  Methodically.  One piece at a time.

Like all those pursuing the art of photography, this is more than just a job for me. I want to make the images I see in my mind a reality. I want to make an interesting and lasting footprint. I most assuredly have a long way to go and it's a never ending process.

I serve the greater Los Angeles and Orange County Region, but I travel domestically or internationally as assignments require.

I specialize in environmental portraiture and headshots.  I travel to location to do shoots, and as such, I do not have, nor do I use a studio.
