Matt Brandon of The Digital Trekker did such a great job of explaining how depth of field does not change with focal length (considering aperture stays the same) that I am not going to type it all up again, but instead, link directly to his post.
What Matt says in this post is fairly simple for some, but mind-bendingly difficult for others to conceptualize. We’re all wired differently but I think Matt’s way of explaining the concept works well. Basically he’s pointing out, through a clickable image, how depth of field does not change with varying focal lengths.
The important caveat here is that he kept the subject the same proportions in the field of view. You have seen this in Hollywood films and it is known as the Vertigo or Dolly Zoom effect because the camera is moved closer, or further, from the subject on a dolly to keep proportions the same while changing focal lengths. Such as shown here:
This can further be verified by playing with a depth of field calculator such as DOF Master.
If I go to the site and put in Canon 7D, 20mm lens, f/8 and a subject distance of 3′, I get a total depth of field of 2.31′.

Professional or amateur, all photographers can agree shooting during the magic hour can produce aesthetically amazing results. Landscape photography especially shines during this period, but the magic hour is not restricted to landscape alone. Amazing portraits can be captured during these brief, beautiful times of the day.
Before you sprint out with a client, couple, or model there are a few things you should keep in mind to help you produce the best quality image during this period. For beginners, the magic hour is the first and last hour of sunlight during the day. The appeal of magic hour (or golden hour as some call it) stems from the warm glow, soft light, and saturated colors this time of day provides.
Still, like nighttime portrait photography, your camera alone may not capture images fully encompassing your subject along with the landscape. Expose for your subject, and the extra light could eliminate the visceral effect of magic hour as your portrait’s background. Expose for the landscape, and you could leave your subject in silhouette. This can give you great images, but you’re going for a picture where both foreground and background are well lit.
This is where off camera lighting comes into play. Using an extra off camera strobe or flash will allow you to expose for the background, while properly lighting your subject with simultaneously. I conducted a photoshoot with a close friend and model to demonstrate. Here a few guidelines.

It’s possible to produce quality studio portraits without a purpose-built studio or expensive lighting equipment. I captured the above image using two hotshoe flashes, a medium-sized portable softbox, and a white wall as the background.
In this post I will share a simple two-light technique that you can use to create a high-key headshot in your own home, using only a plain white wall as the background. I made this portrait of my wife in a small room in our house.
Camera: Canon EOS 5D Mark III
Lens: Canon EF 100mm f/2
Background Light: Canon 430EX II bare flash
Key Light: Canon 430EX II in 24″ Lastolite EzyBox softbox
Flash Trigger: Canon ST-E2
Lighting the Background
The key to pure white backgrounds is to light the background separately from the subject. For this portrait, I placed a single flash on a light stand, hidden behind the model, and pointed the flash directly at the wall. The flash was zoomed to it’s widest setting, and I also flipped down the built-in diffuser to further spread the light onto the wall.
