The Monochrome Railroad

Slow Train Coming - Promontory Summit, Utah
I've captured railroad photographs many times before. It's not my main photography genre, but it is one of the subjects that I find myself coming back to often.

I've visited a couple places in Utah since moving here that have allowed me to capture classic railroad images in black-and-white. One is the historic Ogden Union Station, which has a number of old locomotives and train cars on static display. The other is the Golden Spike National Historic Site, which does a reenactment of the completion of the first transcontinental railroad one day per week in the summer.

Places like these allow you to create images that look like they are from a time long gone. These are the type of images that the legends of photography might have made decades and decades and decades ago. They don't look like modern scenes.

I used an LG G4 to capture these photographs. A cell phone is a perfectly good photographic tool, just as long the photographer is also capable. I used Google's Snapseed to post-process the RAW files right on my phone.

Image Quality vs. Viewing Size

Stars Above Sharps Hallow - Morgan, Utah
LG G4 @ ISO 1000.
I received a surprising amount of positive feedback to my ISO 1000 night image captured with an LG G4. High ISO and tiny sensors don't mix well, and image quality noticeably suffers. ISO 1000 is above the practical high-ISO limit of the G4, and so the image is especially noisy. And because of the amount of noise reduction applied, it's also a bit soft.

For many viewers none of that mattered.

I think some people simply overlooked it. No one will notice an image's flaws as much as the photographer. I know every imperfection very well because I'm the one who created the photograph. You might not look closely enough to even spot them. You might appreciate the image for what it is and move on fast enough to miss the things that you don't really care about.

I think for a large number of people, it has more to do with the viewing size than anything else.

You are seeing the image, either on your tiny cell phone screen or a bit larger computer monitor, only a few inches by a few inches big. It's probably not much bigger than a dollar bill, and maybe it's significantly smaller than that. And your eyes are likely 18" to 24" away from the screen. You are viewing a small image from a distance. It's harder to see the flaws.

Here's the interesting thing: the larger an image is, the further away it will be viewed. We do this naturally without even thinking about it--it's subconscious. If you print something big, people will automatically move further away to see it. They can't take it all in if they are standing close.

In some cases, like at some art galleries and exhibits, people are purposefully placed close to the images to force them to view them closely. They want you to appreciate the fine details. And in your home, you might put a picture on your hallway wall where the viewer can't step back, which forces them to view it closely. Typically, people will only look closely if they have to look closely. Otherwise, the natural instinct is to move back (and the larger the image, the further away people will stand to view it).

If you have a flawed image, like Stars Above Sharps Hallow, which has some serious image quality issues, don't force your viewers to see it close up. Display it in such a way that they'll view it from a distance--that's what they'll subconsciously want to do, anyway.

Of course there are "pixel-peepers" who want to study images up close. They are often more concerned with image quality than the message of the image. I think that most photographers are pixel-peepers (especially to their own images) and most non-photographers are not. If your audience is largely made up of pixel-peepers, they are more likely to notice flaws.

The point here is that you can have poor image quality and still have a good image. Ansel Adams said, "There is nothing worse than a sharp image of a fuzzy concept." The concept matters more than the image quality. Obviously you want both a sharp concept and a sharp image. But if you can't have both, it's better to have a sharp concept than a sharp image.

People--especially non-photographers--care much less about image quality than you think they do. And very few look as closely at your photographs as you imagine they do. You notice the flaws, they don't. So it's alright if your photographs have flaws, just make sure your concepts don't.

Astrophotography With A Phone - LG G4 & High ISO

Stars Above Sharps Hallow - Morgan, Utah
ISO 1000, f/1.8, 30 Seconds, LG G4.
Astrophotography with a cell phone? Sounds impossible. But is it?

I got a phone adapter for my tripod, and I thought to try it out photographing stars. Utah has some of the best sky for astrophotography because once you get away from the towns and cities, there is almost no light pollution. Astrophotography requires a dark sky in order to really capture the stars.

My new LG G4 has manual controls, including up to 30 seconds exposure, and can save in RAW. I knew that high-ISO is not a strong point for the G4 because of its tiny sensor, but thought to give this a try anyway.

After finding a dark spot, I set the phone on the tripod and got the settings in order: ISO 1000, 30 seconds exposure, and manual focus to infinity. The aperture is permanently set to f/1.8, but that's a good f-stop for this kind of photography. I didn't worry about white balance because that's easily adjusted in post-processing. I also set the self-timer to three seconds just to avoid any camera shake.

Once the shutter was open, I used an LED flashlight to "light paint" the foreground hill. It was dark and would have been almost entirely black if I had not done this.

The results? Mediocre. But better than I would have guessed.

The LG G4 has a practical high-ISO limit of ISO 600, which is quite good considering that the camera has 16 megapixels stuffed onto a tiny 1/2.6" sensor. Going above ISO 600 is going to produce less-than-stellar results. ISO 1000 is the highest you'd ever want to go with this camera, and the digital noise at this ISO is too much for my tastes.

A long exposure, however, adds even more noise because the sensor gets hot. Most digital cameras offer long-exposure noise reduction to compensate, but not the G4. So you have noise on top of noise.

I post-processed the RAW file using Alien Skin Exposure X. It was a tough balancing act between noise reduction and sharpness. I think the largest that this photograph could be printed is 8" x 12" and that may be pushing it. For internet viewing it's alright.

Here are two more images captured with the LG G4 that same night, post-processed using Google's Snapseed:
Night In Weber Canyon - Mountain Green, UtahISO 1000, f/1.8, 30 Seconds, LG G4.
Nighttime In Sharps Hallow - Morgan, UtahISO 1000, f/1.8, 30 Seconds, LG G4.
As you can see, Snapseed didn't do a great job with these images. I've been impressed with Snapseed otherwise, I just don't think it had a lot to work with here. The LG G4 just doesn't produce good files at ISO 1000.

Amazingly, it's possible to do astrophotography with a cell phone, and the LG G4 is one of the best options for this. But it's not really all that practical, as the mediocre results make you wish that you'd used a better camera--one with better high-ISO capabilities.

News: Hasselblad Introduces The X1D - First Mirrorless Medium-Format Digital Camera

Hasselblad has just announced a new camera: the 50-megapixel mirrorless medium-format X1D. They also announced two lenses to go with it, since the camera has a unique mounting system: a 45mm f/3.5 and a 90mm f/4.5. The camera will cost $9,000 for just the body, or a kit with both lenses will cost $14,000.

The camera is small for medium-format, but it's not small. It's larger than many full-frame cameras.

50-megapixels is a lot of resolution, but not necessarily for medium-format. In fact, you can find that much resolution in a couple of full-frame cameras. Even my old Nokia Lumia 1020 cell phone has almost that much resolution. Resolution is resolution, no matter the sensor size.

This is what 40-megapixels look like.
What a larger sensor gives you is a larger dynamic range and better high-ISO capabilities. But with advances in digital technologies, this has become less and less true--the advantage is not nearly as big as it used to be even just five years ago.

Besides that, as street photographer Eric Kim said, more megapixels equals more problems. More money. Bulkier gear. More storage. Slower software. And very few people actually need any more than 16-megapixels, so most of the resolution is wasted.

That's not to say that the Hasselblad X1D is a bad camera. In fact, it's probably a really good camera. But at a price tag that's similar to a used car, it's not a good value. But Hasselblad has never been known for it's value.

A Move To Utah With A Camera In Hand - Part 3: Arizona To Utah

Northbound On Interstate 17 - Flagstaff, Utah

This update is long overdue. I've been in Utah for a little while now. So let me get right to this.

After saying goodbye to family, we left Phoenix in the morning and found ourselves in Flagstaff for lunch. After that we headed north on U.S. Highway 89. This was the first time that either of us had ever traveled this route.

The pine trees quickly gave way to a more desolate landscape. Vegetation became almost as scarce as the population. This is a vast and lonely place. Yet it is extraordinary beautiful, with interesting features and subtle surprises.
San Francisco Peaks - Flagstaff, Arizona
We didn't make many stops. Most of the photographs in this post were captured while driving--one hand on the wheel and the other on the camera. We were moving, not vacationing.

One stop we did make was at Navajo Bridge at Marble Canyon. This is near Lee's Ferry. This site is worth stopping if you ever find yourself in the area. It's like a small Grand Canyon that you can walk out over.

We arrived at our hotel in Cedar City, Utah, just as the sun dipped below the horizon. This was a long day of driving. I would have loved to have stopped more often for picture-taking, but that would have made this day even longer.

All of these photographs were captured using a Panasonic Lumix DMC-ZS40 as JPEGs. Why? Because I needed an easy travel camera for quick snaps. Because I knew I wouldn't have time to edit RAW files. This camera did just what I needed it to.

Wildlife Photography ...At Cabela's

Bear On A Rocky Cliff - Farmington, Utah
I like to occasionally explore genres of photography that I don't normally shoot. One genre that I haven't done a lot of is wildlife photography.

Every now and then I have photographed wildlife. I've captured some birds and elk and such. But these type of images are few and far between.

Recently I had the opportunity to photograph a bear, a fox and a coyote. This is wilder wildlife than I have captured in the past! What might be unexpected is that I never left the city to make these pictures.

You see, I visited a Cabela's store. They have taxidermy animals staged throughout the store. This gave me the opportunity to photograph animals that I otherwise wouldn't.

Is this cheating? Yes and no. It's cheating because it is fake--you can probably tell that by looking closely. It's not cheating because photography is whatever you want it to be. There are no rules (or, the "rules" that exist should be ignored). If I want to photograph taxidermy animals posed as live animals, I can. It's my art.

I think it would be great to head out into the forest with a camera to photograph real wildlife. But that's not practical for me right now. Maybe someday. For now, I'm happy with the faux wildlife pictures I captured at Cabela's.

I photographed these using my new LG G4 cell phone, editing the RAW files using Snapseed.
