Impromptu airshow

Posted on by

It’s been years since I’ve had the opportunity to attend a local airshow. But then a few weeks back I realized that during football season, people in the Denver area are given a free mini airshow before each Broncos (NFL) home game. There’s usually a military aircraft flyover for home game kickoffs and the pilots fly laps for about an hour to get the timing right for their flyover — and best of all for me, I live a short drive from where they circle.

Throw in a bit of help from the ADS-B Exchange, and it’s pretty easy to get lined up for some good shots (weather permitting).

All the photos in this post were taken with an OM-1 II camera and M.Zuiko 150-400mm + TC1.25x lens (at full zoom, so 1000mm in 35mm terms). Unfortunately, I had to crop all these shots due to distance; next time, I’ll remember to bring a teleconverter. And now that I’ve spotted some patterns in their flight path (it’s broadly similar from game to game, but shifts around by a few miles each time), I should be able to start getting closer. FWIW, these two aircraft are U. S. Navy EA-18Gs, the electronic warfare versions of F-18s.

“Spirit Guides” at the Denver Botanic Gardens

Posted on by

I recently had the opportunity to see the “Spirit Guides” exhibition at the Denver Botanic Gardens. Scattered amongst the plants were a series of 8 sculptures — imaginary hybrid animals inspired by the Zapotec calendar — made by Jacobo and María Ángeles of Oaxaca, Mexico.

This colorful fellow is poised to greet you, right as you enter the gardens. As you can see, he’s a tall one.

These hybrid creatures combine two kinds of spirit animals from Zapotec legend — one represents a protective animal, the other is a spirit animal with personality traits similar to yours. Continue reading →

Mobile backups — don’t lose your photos when you’re on the move!

Posted on by

(Hopefully) most photographers have settled on a good backup scheme for use while they’re at home. Backups can be life savers when it comes to protecting against data loss — whether due to human error, hardware failures, software problems (either accidental or due to a hacker’s intrusion), theft, even natural disasters.

But of course, it’s easier to have and use a robust photo backup approach when you’re sitting still in your own home, compared to when you’re on the move. Routinely backing up your photos while you’re traveling introduces a number of challenges and complexities. You have to contend with limits on the weight and size of your backup hardware, you may or may not be able to count on a WiFi connection, and you’ll have additional constraints on your time. In particular, it’s much more challenging to do automatic (set-and-forget) backup while traveling.

But fear not, gentle reader — not all is lost on the mobile backup front. The march of technology has been a big help to us lately.

The new OM System OM-1 Mark II — my first take

Posted on by

On January 30, 2024, OM System announced an upgrade to their previous flagship camera. The OM-1 was released early in 2022, and is now being replaced by the OM-1 Mark II. As you might expect, there is no shortage of commenters online — some are enthusiastic fans of the upgrade, others quite disappointed by it.

I… have some thoughts.

Mind you, I definitely haven’t had access to one of the new bodies, and they won’t “hit the street” for until the end of February (at least, in the U.S.), so what follows is based on published data and early reviews.

Fun with infrared light and modern architecture

Posted on by

Over the past few years, I’ve dabbled here and there with infrared (IR) photography, but didn’t take it very seriously until I recently took an online course in the subject from Derrick Story (a.k.a. The Nimble Photographer). If you’re at all interested in IR photography, I can highly recommend the seminar — you’ll learn a lot from the instruction, and quite a bit as well from your fellow students.

In particular, one of my fellow students recommended taking IR photos in office parks with mature vegetation. You can, he said, get some nice results with the architecture, windows, and greenery.

So as my first example of this subject matter, here’s the Pacific Western Bank building in the Denver Tech Center (Denver, Colorado):

The above is a quick reference photo I took with my iPhone — it’s poorly framed but still a good comparison for the images below.

OM-1 Battery Testing

Posted on by

As mentioned in a previous post, I’ve been mulling over battery options — partially because OEM batteries are fairly expensive, and partially because some 3rd party options have potentially attractive additional features.

I’d gotten busy with regular life activities, and almost forgotten about my promise to do some testing, when I ran across this interesting video on YouTube. In the video, a Finnish gent tests an OEM BLH-1 battery and some 3rd-party replacements for it, using an OM-D E-M1 camera. I liked his approach, with a few provisos — namely, that I think using the internal intervalometer was causing him some of his issues (camera stops recording before the battery is fully discharged, residual charge level varies from battery to battery).

ProMaster batteries — a good option for the OM System OM-1 camera?

Posted on by

When the folks at OM System (formerly Olympus Imaging) released their new flagship camera, the OM-1, it came with its own new high-capacity battery — the BLX-1. As is usually the case with new battery designs, supply was tight at first. But pandemic supply chain issues (and maybe other problems) have helped keep supply tight since then, and prices for BLX-1 batteries have only gone up in the meantime.

So what’s an OM-1-loving / cost-conscious photographer to do? Plenty of 3rd-party batteries are available on various websites, with varying price, performance, reliability, and safety. I’ve seen good results from ProMaster accessories in the past, so I thought I’d give their batteries a try, particularly since they’ve recently introduced BLX-1 “equivalents” with a twist — built-in USB charging. What follows is a “first impressions” view of the situation (more details will follow in a later post).

Visual overview

Batteries compared, bottom viewLet’s start visually. Here’s a bottom view of three batteries that I’ll be comparing — an OM System BLX-1, a ProMaster replacement, and a ProMaster battery with built-in charging. If you were curious, I purchased all of them — no vendor-provided stuff here.

LS-P4 vs. LS-P5 audio recorders — an early comparison

Posted on by

The fine folks at OM System have just announced the upcoming release of their new LS-P5 audio recorder (it’s now available for pre-order). A variety of tutorial-centric videos have been released as part of this announcement, but I couldn’t find a direct comparison of the LS-P5 to its (slightly dated but still pretty good) predecessor, the LS-P4 (update on that situation is below).

So based on available information, I pulled together my own high-level comparison — I’ve got an LS-P4, and wanted to know if the new gadget would be worth the upgrade for me. Continue reading →

SmallRig cages compared — Olympus E-M1III vs. OM System OM-1

Posted on by

Like many photographers in the Olympus / OM System world, I’m in the process of upgrading my photography gear from the E-M1III to the OM-1. Fortunately, SmallRig just started shipping a camera cage for the OM-1, since their long-unavailable cage for the E-M1II (which also fit the E-M1III) does *not* fit the OM-1. Before I sell off the old cage, I thought it might be helpful to compare the two models for anybody that may be in the market for one or the other.

At a high level, there are some key changes: some mounting points went away, or moved; the overall shape changed just slightly (in the process, access to body-front buttons is improved); and the new cage has a built-in Arca-Swiss mounting plate and captive attachment tool.
