Making Photos POP!

Nikon D5, Sigma 35mm ƒ/1.4 DG Art, ISO 100, ƒ/1.4, 1/2500
Selective Focus is what makes people pop out of photos or the backgrounds recede in a blur. And you make the choice of what pops, what blurs, and what fuzzes over.

Where do you want the viewer to focus their attention - the hedge in the foreground, the man in the middle, or the trees in the distant background? Many professional photographers use the selective focus technique to control the viewer’s attention.

The apertures, called f-stops, are actually fractions. The f-stop ƒ/4, for example, is really ¼ (one fourth). What one fourth of, is a little beyond the scope of this article.  Let’s just say that an f-stop is a fraction, ok? (ƒ/4 = 1/4th  f8 = 1/8th). Typically these numbers are on the lens, 2.8, 4, 5.6, 8, 11, 16, 22 and so on.

Remember these are actually fractions: 1/2.8, 1/4, 1/5.6, 1/8, 1/11, 1/16 and 1/22. It provides a comparison of how much light each number lets through the lens. Therefore 1/5.6 allows more light through the lens than 1/22.

Nikon D5, Sigma 35mm ƒ/1.4 DG Art, ISO 180, ƒ/8, 1/100

Here’s the creative part: the smaller the opening (f-stop) in the lens, the less light is allowed in. Therefore, a greater area is in focus from the foreground to the background. If you want to throw most of the background out of focus, use ƒ/5.6 rather than
ƒ/22.

Today’s digital cameras allow the photographer to vary the aperture, preview the results, then make a decision about it’s effectiveness.

If you want the subject to “pop”, use the larger lens openings, i.e. ƒ/4 or ƒ/5.6. Like a simple sentence, having one distinguishable subject is better.

A smaller aperture (ƒ/16 or ƒ/22) brings the foreground and background into sharper focus or a greater depth of field. It also allows for other compositional techniques to direct the viewer to the main subject of the photo.

Setting your cameras ISO, shutter speed, and aperture provides more than a properly exposed photograph. These are tools you can use to compose and say what you want to say in your photographs.

Nikon D5, Nikon 85mm ƒ/1.8G, ISO 100, ƒ/10, 1/320
Experiment using different ƒ-stops. Try setting the camera to the aperture preferred setting. Explore the creative tools available on the camera. If the camera is always set on automatic, it becomes into a very expensive box camera.

Turn your aperture dial to help direct the audience

Nikon D5, Sigma 35mm ƒ/1.4 DG Art, ISO 100, ƒ/1.4, 1/800
A shallow depth-of-field like ƒ/1.4 that I used here is a great way to force the audience to look where you want them to see.

Nikon D5, Sigma 24-105mm f/4 DG OS HSM Art Lens, ISO 14400, ƒ/11, 1/100
Now using a deep depth-of-field like ƒ/11 as I did here really helps keep the eye moving all through the frame.

Nikon D5, Sigma 35mm ƒ/1.4 DG Art, ISO 100, ƒ/1.4, 1/500
Don't fall in love with an ƒ-stop. Use what helps you for that moment. The danger of always shooting ƒ/1.4 for example is that you really are not giving context to your subject.

Nikon D5, Sigma 24-105mm f/4 DG OS HSM Art Lens, ISO 4500, ƒ/4, 1/100
Here I used ƒ/4 which was just enough depth-of-field to show the lady's kitchen and her cooking.

Nikon D5, Sigma 24-105mm f/4 DG OS HSM Art Lens, ISO 4500, ƒ/4, 1/100
The point here is that you just don't turn the ƒ-stop/aperture from one end to the other. Use just enough to help you show that which you need the viewer to see. Again the ƒ/4 was adequate enough while shooting with the 24mm to capture the rest of the kitchen.

Want Silky BOKEH? Get Closer!

Nikon D750, Micro‑Nikkor Macro 60mm f/2.8 D, ISO 12800, ƒ/5, 1/200
I am shooting wide open with the Micro‑Nikkor Macro 60mm f/2.8 D lens. Now since I am as close as the lens will let me focus, which gives me a 1:1 ratio the ƒ-number gets bigger due to the lens extending and actually getting further from the sensor.

Nikon D750, Sigma 35mm ƒ/1.4 DG Art, ISO 1800, ƒ/1.4, 1/200
This is as close as I can focus the Sigma 35mm ƒ/1.4 DG Art lens [11.81"] of the same Christmas ornament.

Nikon D750, Micro‑Nikkor Macro 60mm f/2.8 D, ISO 7200, ƒ/4.8, 1/200
Here is another Christmas ornament for comparison.

Nikon D750, Sigma 35mm ƒ/1.4 DG Art, ISO 900, ƒ/1.4, 1/200
Notice how much Charlie Brown's sister Sally is out of focus at ƒ/4.8 vs ƒ/1.4 in the two photos. The depth-of-field is even more shallow in the closer photo. This is because how close you are to the subject has as much impact on depth-of-field as your aperture.

Nikon D750, Micro‑Nikkor Macro 60mm f/2.8 D, ISO 12800, ƒ/4.8, 1/200
In this Citadel Christmas ornament you can see how super shallow depth-of-field is at ƒ/4.8 as compared to the photo with the Sigma 35mm ƒ/1.4 below.

Nikon D750, Sigma 35mm ƒ/1.4 DG Art, ISO 1250, ƒ/1.4, 1/200
Now just to let you see how your distance impacts the depth-of-field here I just backed up just a hair in the lower photo of the ornament with the Micro‑Nikkor Macro 60mm f/2.8 D.

Nikon D750, Micro‑Nikkor Macro 60mm f/2.8 D, ISO 9000, ƒ/4, 1/200
Since I backed up the aperture opened up a little, so you would think the depth-of-field would shrink but just the opposite happened. Again this is due to the distance to the subject.

You want silky smooth BOKEH? GET CLOSER!!!

Deep Depth of Field

Nikon D2X, Sigma 15-30mm, ISO 100, ƒ/14, 1/15
You would think by looking around the industry that everyone is shooting wide open at ƒ/1.4. There are some places like Country Living Magazine that actually want just the opposite for their viewers.

Why would someone want everything sharp from front to back in a photo?

Many people are looking for decorating ideas and want to see the details. The other thing that a deep depth of field does for the viewer is put them into the space. They can now let their eye roam from front to back in the photo and all around.

You see a deep depth of field pulls the audience into a scene more than a shallow depth of field. The shallow depth of field helps you isolate a subject within the frame and the deep depth of field does just the opposite and gives more context for the subject within the frame.

When Country Living hired me to shoot this assignment I was given very specific instructions that they needed the greatest depth of field possible in all the photos.

Here are some more photos from that shoot.

Depth-of-field is more than Aperture

[Photo 1] Egypt—Missionary Mike Edens (left) worked closely with Egyptian Baptist pastors trying to enhance their discipleship and pastoral ministries. These pastors—(left to right) Mikhail Shehata Ghaly and Anwar Dakdouk—took MasterLife discipleship training in Cyprus during 1984. [photo by Don Rutledge]
Technically Depth-of-field—is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.
Don Rutledge
I have never met a photographer who understood more about packing more into a frame to tell a story than Don Rutledge.

The reason is it takes a lot more ability to take a photo of what appears to be clutter and compose it in such a way that you capture a story than it does to isolate by either getting closer or zooming in and isolating a subject.

What Don Rutledge taught me and yet I still haven't begun to execute it as well as he did was to use the environment around the subject to provide context and tell a better story.

He taught me to spend time with a person before I take a photo of them. Spend time getting to know their story, this way once you know them you start to see things around them and their body language that help inform the audience through visual clues as to who the subject is as a person and how they interact with people in their world.

[Photo 2] Cincinnati, Ohio, 1968: Children with a trophy of the streets. [photo by Don Rutledge]
Don taught many photographers not to just watch the edges of the photograph but pay attention to the "Depth-of-field" when making the photograph. He wanted to use the thing in the foreground and background more than any other photographer I knew to help tell the story.

In Photo 1 you can see down the street and around the men as they walk down the street in Egypt. While most everyone is laughing as if a joke was just told—notice the woman just behind the men. Her expression tells another story.

I can picture this woman being similar to the woman in Matthew 9:20, “If I can just put a finger on his robe, I’ll get well.” Jesus turned—caught her at it.

She is not apart of the men's group but has an interest in them.

In Photo 2 you see not just the rat being held by the boy but his friend and the place of their discovery. His friends body language adds so much to the context as does the alley where they found it.

[Photo 3] This is early morning in Mississippi for Luvenia and Bailey King. King sleeps as his wife puts breakfast on the table. [photo by Don Rutledge]
To get this type of "Depth-of-field" Don invested time with his subjects. In 1979 Don spent a month living with the King family in Mississippi. He added just enough money to the family budget to not add any financial stress on the family, but also not to change their living standards so he could cover what it was like living below the poverty line in America.

This photo [Photo 3] became a favorite photo of many from the story. The photo captures Bailey King and shows how thin he is and how hard his wife also worked to provide for the family. It is not a photo just about Bailey, but his wife as well Luvenia.

[Photo 4] Appalachian migrant family in Ohio during 1968. [photo by Don Rutledge]
Here in Photo 4 you can see a father who is obviously concerned and then you see his children in the background. The children are like all children and pull the viewer into the story of a migrant worker who will travel wherever finding work to provide for their family. Many photographers would crop just above the father's head and left out the boy in the window. The reason is they most likely would not have seen the boy.

Don had a patience about him that let him truly be in the moment. He could see things that most missed. I think Don really and truly had more empathy for his subjects than just about any other photographer I have known.

[Photo 5] Africa—Sally Jones (white coat) felt emotions well up inside as she shared this moment with concerned mothers at the Southern Baptist feeding and health care center's clinic in Ethiopia.
Many photographers might crop in much tighter on Sally Jones in Photo 5 here. Don goes wide and gets really close to be sure you see her expression. I remember often seeing the contact sheets of moments like this when Don was editing. He would show me the moment before and after where sometimes the lady in the background was only there for one of maybe 10 frames. She adds so much by helping pull you to the background after you have already seen Sally. There are more mothers outside is what this helps to convey.

[Photo 6] Israel—Missionary kid Sommer Hicks plays on the rocks of the sea of Galilee with her dad, Ray Hicks, in the background. [Don Rutledge]
So often photographers get so focused on the main subject they forget that those around the subject can sometimes give us insights into them. Here we get a glimpse of how normal life is for Ray Hicks in Photo 6 when we see how much fun his daughter is having at the sea of Galilee. Don shot it in a way to bring Ray into the photo and give a context that Don did so well time and time again.

Please take a look how often Don uses depth in his photos to tell stories. Here are two coverages of Russia that Don did in the 1980s. Don shot these for a magazine which would only use on average maybe 8 to 12 photos, but look at the true depth of his coverage. I remember seeing these coverages up on so many light tables and Dan Beatty commenting on how he could tell so many stories whenever Don returned.

Sigma 70-200mm ƒ/2.8 great lens for party pics

Nikon D4, Sigma 70-200mm, ISO 12800, ƒ/3.2, 1/80 optical stabilization on
I love to watch people and especially across the room. The lens that captures these moments the best for me is the Sigma 70-200mm f/2.8 EX DG APO OS HSM for Nikon. Up to 4 Stops of Optical Stabilization makes hand holding the lens possible in low light, which I was shooting in tonight.

Nikon D4, 85mm ƒ/1.4 , ISO 450, ƒ/1.4, 1/100
I tried to work the room with the Nikon 85mm ƒ/1.4 but I felt like the lens was too loose most of the time and since I was further away the depth-of-field actually was as silky smooth to me as with the Sigma 20-200mm because I was able to shoot at 200mm and therefore compressed the background.

Nikon D4, Sigma 70-200mm, ISO 12800, ƒ/3.2, 1/50 optical stabilization on
The cool thing shooting at 200mm and wide aperture gives the shallow depth-of-field making the subject pop out from the room.

Nikon D4, Sigma 70-200mm, ISO 12800, ƒ/2.8, 1/60 optical stabilization on
While technically the subject is separated from their environment you now must wait for a moment where you capture the personality of the person. Having a technically great photo isn't what make the photo, but just merely helps. It still comes down to capture the moment.

Nikon D4, Sigma 70-200mm, ISO 10000, ƒ/2.8, 1/100 optical stabilization on
Now while I am shooting all these photos the people are aware of me, but I have been working the room for a while. I started with 14-24mm and introduced myself to people getting them to know I am here and taking photos.

Nikon D4, Nikkor 14-24mm, ISO 12800, ƒ/3.2, 1/100
Shooting a full-framed image like the one above here with the 14-24mm put me less than a foot from the subjects. After shooting these I then start shooting the tighter shots with the longer lens. I am now further away and picking moments.

Nikon D4, Sigma 70-200mm, ISO 9000, ƒ/3.2, 1/100 optical stabilization on
Now people are more relaxed at the party. They are now into conversations and enjoying one another. This is when I get the really good expressions.

Nikon D4, Sigma 70-200mm, ISO 12800, ƒ/2.8, 1/100 optical stabilization on
I love also create a layering effect by having something in the foreground and background. I think this helps give more depth to the photo even with the foreground and background out of focus.

Nikon D4, Sigma 70-200mm, ISO 11400, ƒ/3.2, 1/100 optical stabilization on
I love these expressions. They make you want to know what they are talking about.

Nikon D4, Sigma 70-200mm, ISO 12800, ƒ/3.2, 1/100 optical stabilization on
I love shooting tight and isolating subjects, but remember when I am writing a blog like this I am teaching something. This is just part of the coverage, I have a great deal of wide-angle lens shots to help capture the context.

I think just about every photographer would benefit from a 70-200mm ƒ/2.8 lens in their bag. I love my Sigma 70-200mm.

Shallow depth-of-field @ ƒ/9 can give great Bokeh

Nikon D3S, 28-300mm, 100mm ISO 200, ƒ/9, 1/200
When you first think of ƒ/9 you might think of the photo above where you can see from the lady to the sign behind her that most of photo is in focus, but that the far background of the building is out of focus.

I have written on this topic before in a different way and even created a video on it. Here is that link.

This is a little different perspective on the topic using the new Fujifilm X-E2.

Nikon D3S, 28-300mm, 300mm ISO 200, ƒ/9, 1/125
Now in this photo here you might not realize it too is shot at ƒ/9.  Two things helps with the silky Bokeh in the background. First, I am now shooting at 30mm verses 100mm at ƒ/9 and second the background is far enough in the background that it is out of focus.  It is about 100 ft from here.

Nikon D3S, 28-300mm, 150mm ISO 200, ƒ/9, 1/200
In this photo she is standing not too far from where she was in the first photo. However the shallow depth-of-field is helped by the distance from the building, the 150mm focal length.  

Same photo from above but just cropped
Now when you enlarge the photo you will see the eye closest to the camera is tact sharp. But the next eye is ever so slightly soft, but by her hair by her ear we are out of focus.  

Things that affect the Bokeh of the background in photos
  • ƒ-stop: The wider the aperture with everything else the same, then the depth-of-field becomes shallow
  • Distance to Subject: The closer you are to your subject the shallower the depth-of-field will be.
  • Subject distance to background: The greater this distance the more likely the smoother look of the Bokeh

All were shot on tripod at the very closest focusing distance that the lens would focus on the eyes at ƒ/1.4. The only thing I changed was the aperture and the camera adjusted the shutter speed to keep the exposure the same.

Approximately 100% view of the ƒ/1.4
You can increase your depth-of-field by just backing up from the subject and this will increase it for you. Conversely if you want a shallower depth-of-field get closer if the lens allow you.

When you are super close you are not looking for Bokeh

Macro photography you are actually needing a large aperture or the photo can look out of focus even when it is in focus.
