Project365 - Of Grids and Snoots

Introduction

I managed to collect the components of my Honl speed strap & gels system yesterday. They also make a grid, so I picked one of this up up as well. Grids & Snoots are another form of light modifier for your flash system. They don't change the colour temperature of your flash, instead they focus the beam.

Why would you want to do that ? It allows the photographer to more selectively light the scene. Imagine a photo of a model in a dark room. Perhaps you want to expose the background to look like a black backdrop. That's easily achieved, but you still need to light up the model, to show off contrast and colour. The grid or snoot will help "aim" the light at the models face, while minimizing the spillover onto the background.

 

The Setup

These are some more "goofing around" shots. None of my available models were out of bed yet, and I was getting impatient. A very simple setup, with the Honl 1/8 grid attached to the Canon 430 EX II via the Honl speed strap. The whole shebang is mounted on the hotshoe of my Canon 60D, which has my general purpose 24-105mm f/4 L lens attached. I shot handheld for quick & dirty testing.

 

The Photos

A simple before and after shot. First without the grid, followed by a photo taken with the grid.

Note the even lighting. I used no other light modifier, like a gel, as there was no other ambient light - just the flash at 1/8 power.

 

 

 

For comparison, this photo is shot with the exact same settings, and the grid in place. Note how quickly the light falls off ! The grid directs the flash down a very narrow beam.

 

 

 

Lessons Learned

The use of a grid or snoot allows more creative use of light. It provides an easy way of selectively lighting a small portion of the frame, while quickly allowing the ambient light to light the rest. I see this as very useful for fill-flash and portraiture.

Project365 - Two Strobe Portraits

Introduction

In my last installment, I refined my technique for creating a deep black background. In this shoot, I applied that technique, along with two flashes to create more interesting portraits.

 

The Setup

My thought was to set up for a black background, and then light the model from above and to her right. Then, I wanted to place another strobe below and behind her. I was hoping to create a sort of light halo effect. Unfortunately, I didn't get the halo as her hair was as dark as the background. Worse, I had remarkably dark shadows across her face.

I shot the Canon 60D handheld. In the hotshoe was one of the Cactus v5s. I was set for a black background - f/250, ISO 100 and an aperture of 16. One Canon 430EX II was mounted on a Cactus v5 atop a tripod to the kodel's right, while the other was mounted on the trigger and placed on the floor.

The Photos

I am still learning about portraiture. It's not really something I'm very good at, so I was fortunate that my daughter agreed to be my model. It is easy to have a good rapport...

In this first photo, the main light was too powerful. While I had a nice dark background, you couldn't really see any definition between the background and the kodel's hair. And the pose is funny - unnatural, even. It looks like her eyes are pointed in two different directions !

Here, the main light is better, but the secondary is still underpowered. There are very harsh shadows on the models face. Given how pale her skin is, I would've liked to have made her skin tones warmer with a bit of makeup.

 

This one is better. We see a nice cross-lit effect, haloing her cheek and chin. And there is even a hint of catch-lights in her eyes ! But her dark hair is lost in the black background, still.

This is a little bit tighter a shot. I like the effect of the cross-lighting, and the black background.

Lessons Learned

I still need to figure out how to create the halo effect around the model's hair. I suspect my life would be easier shooting at night, when the room is darker to begin with. I'd also like to try to use a reflector to cross-light the face, which would free up the flash for the halo effect !

Project365 - Black Backdrop

Introduction

Today I learned much more about a technique I had attempted once before. Now that I better understood how it worked, I believe I am better able to put it to good use. You see, one of the things that most studio photographers invest in is backdrops. Often large rolls of seamless white or black paper, they allow the subject to be the true focus of the photograph. Who knew I was carrying a black backdrop around in my camera ?!?

It's truly a simple effect involving the use of flash (or sometimes called strobe) photography. Cameras have a maximum speed with which they can sync with the flash to achieve a nicely lit picture, it's usually around 1/250th of a second. Keeping that portion of the exposure triangle still, we next dial down the ISO (the sensitivity of the CCD) to 100. The only thing left that is adjustable is the aperture. All we do is close that down until a picture taken in the ambient light is completely black. Now, anything lit up by the flash will be nicely lit, while the background remains black.

The Setup

Nothing really complicated the Canon 60D, set at f/16, ISO 100, and a shutter speed of 1/250th of a second. The Cactus v5 was mounted in the hotshoe, so I could use the Canon 430EX II off-camera. I placed it on a basic tripod with the other Cactus v5, so I could move the light & the camera around freely.

The Photos

Believe it or not, this is a photo of Pat's flowers on the dining room table. I was setting the ISO, Aperture and shutter speed to get a black background. Got it !

 

Whoops ! The flash was spilling onto the background too much, so I elected to put a snoot on the flash, to more tightly focus the beam.

That's better ! Although you will notice the pen & paper on the tabletop still show up faintly. Now to play around a bit... ;-)

The first few pictures weren't as bright as I would have liked, so they came out a little dull. Time to up the power of the flash a notch, and move the light stand a little closer !

Much better ! I like the contrast created by the various petals on the flowers.

I think this is one of my favorite photographs of the shoot...

Lessons Learned

I thought I really understood this technique, but now with a little better tutorial, I think I know how to nail it whenever I need it. Certainly, implementing the snoot helped narrow the beam, and moving the light stand over to one side helped with not lighting the background. I really like this technique & see myself using it for portrait work.

Project365 - Get Out of the Way !

Introduction

While experimenting with Depth of Field, in a previous post, Pat suggested that using a fork on a plate might be a bit boring ! Instead, she handed me her David Yarmin ring to shoot. It's beautiful, to begin with, but has lots of interesting details - the facets of the stone, the twists in the ring itself, and the detail around the stone.

The Setup

Of course, the camera body was my Canon 60D, and I mounted it on a Manfrotto tripod. Next I mounted the Canon 40mm f/2.8 prime lens, and a 20mm extension tube because my subject was small, and wanted it to fill the frame. Next, I mounted my Canon 430EX II flash with the Cactus v5 triggers on a second tripod, and affixed a 8" snoot to focus the light very tightly. The flash was set to 1/64 power, and a 108mm beam.

The Photos

Oops ! See the orange tinge in the stone and the setting ? That's a reflection off of my t-shirt ! I only noticed it after I started processing the photos. This will never do...

 

 

This one is better. But if you look carefully at the bottom right of the stone, you can see my shadow outlined ! Sigh - another decent photo ruined by an accidental reflection. Next !

 

This picture is pleasing to the eye - no reflections, nice Depth of field, and an interesting composition. I also like how the facets of the cut stone show up, and the position of the flash helps draw out the detail of the mount.

 

 

 

Lessons Learned

As the first two photos illustrate, I must remember to get OUT of my own photos ! Being aware of one's surroundings, and how they might affect the photograph, are of paramount importance to the budding photographer.

 

Project365 - Depth of Field

Introduction

In a previous post, I remarked that there IS such a thing as too much Depth of Field (DoF). I thought it detracted to the composition of the photographs. But then I wondered if I could turn that detraction into an advantage. To me, it seemed to be a good thing to experiment with ! So tonight's Project365 entry is about my experiments with Depth of Field.

The Setup

This was a little bit more complex. Of course, the camera body was my Canon 60D, and I mounted it on a Manfrotto tripod. Next I mated the camera body with my Canon 40mm f/2.8 prime lens, and used a 20mm extension tube. My subject was tiny, and wanted it to fill the frame. Next, I mounted my Canon 430EX II flash with the Cactus v5 triggers on a second tripod, and affixed a 8" snoot to focus the light very tightly. The flash was set to 1/64 power, and a 108mm beam.

The Photos

I shot a great number of test shots, attempting to dial in the settings. These are a sampling of some of the more interesting ones.

Here is one of the early photos of the set. You'll note how shallow the DoF is - not even the length of the tines of the fork ! I like the overall effect, but not the lighting or the background.

 

I turned the fork over, hoping to achieve a more interesting look. The farthest tine is sharply in focus, while the nearest is blurry. I still don't like the background !

 

THIS is more the effect I was hoping for ! The ends of the tines are in focus, and by placing the fork on a white plate, the background loses importance. Best, the blurriness increases as the eye travels down the tines.

 

 

 

Lessons Learned

After about two dozen shots, I started to achieve the look I was after. But it proved that I can use Depth of Field as an artistic part of the composition. Something I wouldn't have understood yesterday !

 

Project365 - Shoot the Snoot !

Introduction
In reading one of the various photography blogs I like, I come across many kinds of instructional "how-to" sections. Sometimes they have videos on YouTube, sometimes it is a vague description. Last weekend, I learned about gobos and snoots. Go ahead, look them up, I'll wait...
The Setup
The camera was my trust Canon 60D, and I affixed my 17-40mm f/4 L lens to it. I shot my Canon Speedlite 430EX IIflash, set at 1/32 power at 28mm. So low power & wide dispersement. Not that it matters when you use a snoot ! (You DID look it up didn't you ?)
The Photos
My semi-willing model puts up with most projects, but this one I expected to annoy her to no end ! Fortunately, I had the flash dialled low enough, she didn't even flinch !

I think I need to learn how to NOT capture the flash reflecting in my kodel's eyes ! You can really see this old dog's cataracts this way.

This photo shows off the snoot well. The light is concentrated on Annie (on the left), while sleeping Sandy remains dimly-lit. This brings the focus to our model.

I purposely shot this photo further back. See how the light falls away ? It accentuates the middle of the frame, while de-emphasizing everything else.







Lessons Learned
I still have a lot to learn about flash photography. This simple technique helps by using a focused beam of light to help accentuate the subject - Annie in this case. This was relatively close-up work. Next time, I might see what happens when I am further away from my subject.
