Cell Phones, HDR and Panoramas

Hi Folks:

This started out as an idea for a blog post, evolved into a one-hour presentation for our local camera group, and now I’ll try to compress that into a blog post. We’ll see how it goes.

There are several questions to begin with, the first of which is… why do this? The answer is to extend or expand the capabilities of your camera, no matter the camera. There are at least five different reasons that I know of to combine multiple exposures into one image. These are two of them. The second question is, why cell phones? This post doesn’t only involve cell phones, but cell phones are ubiquitous. Some people only make images with their phones, despite the technical challenges, but the bottom line is that it depends on how you’re planning to use your images.

An HDR Comparison

Hi Folks:

When you mention the term HDR, many people’s thoughts automatically jump to tonemapping and the results that can produce. That’s not what this post is about. If you don’t understand what HDR is all about or why you might want to use it in your photography, I suggest starting here: Why Use HDR? I’ll wait…

Okay, welcome back. I recently acquired a Sony A7R III and one of the features of this camera is that it has a very wide dynamic range – 12 to 14 stops are claimed. To that end, HDR capture with this camera isn’t often necessary. However, a friend of mine and I were out at Victoria’s famous Butchart Gardens last weekend and I wanted to try bracketing a few exposures just to see. Now, when it comes to the question of how many exposures to make and at what EV levels, there’s really only one answer: it depends. It depends on the scene and it also depends on the camera you’re using and what capabilities it has. For my experiment I decided to shoot 5 bracketed exposures at -4/-2/0/+2/+4 EV. Here’s an example of one of those combined images after having been pushed around a bit in Lr.

Photo of the Month – Discoveries

Hi Folks:

April’s ‘Photo of the Month’ is a little late, but bear with me…  Although I do have a bus pass, I also walk around town – a lot – and in the process I’m always making new discoveries.  A couple of weeks ago I was walking around the Fairfield area when I saw a faded beauty partially protected by an overhang… looked to have been there a long time (30+ years, anyway).  It was something I’d never seen before, but a little research confirmed a 1952 Humber Super Snipe.  For all you non-biologist types, a snipe is a small woodland bird (its use for Quidditch was replaced by the golden snitch in Harry Potter fame but that’s another story).

Photo of the Month – Garry Oak Sunset

Hi Folks:

February has been a strange month weatherwise here in Victoria.  We had the first snowdrops, crocuses and cherry blossoms (not unusual), but we currently have several inches of snow and (comparatively) low temperatures.  I’ve had to bring in the hummingbird feeder at night to keep it from freezing solid.

This month I’ve been playing with a new piece of software: Nik software’s ‘HDR Efex Pro‘.  As you may have read from some of my other Photography posts, I’m not generally a big fan of what some call the ‘HDR-look’.  Having said that, I do understand the value of using HDR imaging for scenes that have an extended dynamic range.  Some photographers seem to think that using film to make images is somehow more ‘pure’ than using digital technology, or that computers allow us to render photographs in ‘unnatural’ ways.  I disagree.  Photographs have been manipulated both in camera and in the darkroom in many ways since their earliest days, including montages.  I have no doubt that if Ansel Adams was alive today he’d be quite happy to apply his ‘zone’ system to Photoshop/ Lightroom or other software.

Why Use HDR?

Hi Folks:

I was at an informal gathering of photographers recently where we were sharing and discussing our work.  I displayed a sunset image that I had made (this one)
