DxO ONE tips: How to shoot longer despite the camera's so-so battery

Two settings in the DxO ONE app that will help your battery last a little longer

It is what it is: The DxO ONE's battery runs down pretty quickly. Here are a few ways to make it last.

1. Don't automatically show the last photo you took

With the DxO ONE connected to your iPhone, go into the gear/settings screen, Capture tab, and set 'Show picture aftershot' (sic) to 'Never.'

This is good advice no matter what camera you're using. Take the time to think about your settings and compose your shots carefully, then have some confidence in the results. Sure, we all glance at a shot now and then, but 'chimping' (looking at every shot) not only eats up battery power, it prevents you from learning to shoot with confidence.

By the way, if you take this tip, you can still see the last photo you took whenever you really want to, simply by tapping the thumbnail in the upper left corner of the DxO ONE app's shooting screen. Tap on the camera icon to return to shooting.

2. Don't automatically write to the iPhone

By default, the DxO ONE is configured to store the master files (say, your raw or SuperRaw files) on the camera's internal card but also to copy a jpeg over to the iPhone. Unfortunately, this default behavior runs the battery down more quickly. So change it. With the DxO ONE connected to your iPhone go to the gear/settings screen, Capture tab, scroll down to 'Store photos on' and select 'microSD card only'.

If you take this tip, you can still move selected individual files to the camera later, if you want to. For example, you might want to process an image on the phone in Photos, or Snapseed or Photogene4 (to name just two of my faves).

And note also that you do not need to move files to the phone just to post to Facebook or Google+, save to Dropbox, or send to a friend by Message or Mail. You can do that right in the DxO ONE app, by selecting a picture and tapping the Share icon.

For some users, there may be an additional benefit to disabling the camera's default behavior. If you have your iCloud account set up to sync photos on your iPhone automatically with iCloud and thus with your computer, you are moving jpeg copies of your DxO ONE photos to the computer through iCloud, and then moving copies of the very same photos to the computer when you import from the camera later using DxO Connect. This may result in you having duplicate copies of jpegs on your computer, in different places. The fewer photos you copy over to the phone, the less troublesome thing problem will be.

3. Turn off the camera when you're not shooting

Unless you're going to take another shot immediately, after you take a shot, slide the lens cover up to turn the camera off. It's easy.

To be honest, this doesn't actually save a lot of battery power, because as of firmware version 1.2 (January 2016), the DxO ONE puts itself to sleep very quickly. But sliding the lens cover shut has two other good side effects that make it worth doing. It minimizes the risk of dust getting into the lens well. And it also solves what can be a pretty regular problem using the DxO ONE, namely, waking the thing up so you can shoot. In my experience, when the camera puts itself to sleep, it will sometimes freeze in that state, so that the only way I can wake it up again is to restart it (slide up the lens cover, then slide down again). Keeping the cover shut whenever I'm not shooting means that, to get ready for my next shot, I simply have to slide the cover down. The DxO ONE starts up in just a second or two and I'm good to go.

4. And just in case, have an auxiliary battery on hand

I love the DxO ONE. It's a terrific camera and it's terrifically portable, so I take it with me just about everywhere, and when I'm out shooting, I really enjoy using it. Unfortunately, because the tiny battery inside this tiny camera is pretty anemic, shooting actively with the DxO ONE means that I run out of power pretty quickly—even following all the tips above.

So I almost always have an auxiliary battery with me. There are a number of these available, but when I was writing the Macworld review of the DxO ONE, one of the folks I interviewed at DxO recommended the Jackery Giant, so that's what I got. It's terrific, too. Unless I'm going to step away from my car for hours, I don't take the Jackery Giant with me. I leave it in the car, and then plug the DxO ONE in when I'm in the car. But the Giant isn't all that big; fits comfortably in my back pocket. Next time I hike the Grand Canyon, I'll carry the Giant with me.

Yay, my DxO ONE's battery is at 100%!

Wireless control of Olympus OM-D E-M1 with OI.Share app

The Olympus Image Share or "OI.Share" app for smartphones allows you to do some very neat things with the Olympus OM-D E-M1 camera, like control focus, shutter and other settings, download photos to your phone, and geo-tag your photos. The only problem with this partnership between camera and phone — at least for me as a micro-four-thirds and Olympus novice — was getting it to work.

The documentation provided in the app and in the user manual for the camera is typically bad. I wrote this blog article from the notes I started making as I was trying to sort this out for myself. I hope I save somebody else an hour and some worry.

Ingredients To get started you'll need to have an EM-1 and a smart phone with the OI.Share app installed. I'm using an iPhone 5 running iOS 7 and version 2.1.1 of the OI.Share app. I downloaded the app from the App Store.

Addendum 7 January 2015: This article was first published a little over a year ago, in December 2013. I just went through the…

Why DxO Optics Pro 10 stays in my toolbox

You can read this post here, or read my reposted version over over at Medium.

I've used over a dozen apps in the last decade to convert my raw files and process my digital images. Today I rely on four main tools to process my images: Lightroom 5.7, the Nik suite of apps (now owned and published by Google), onOne Software's Perfect Photo Suite 9 — and DxO Optics Pro 10. I want to talk about Perfect Photo Suite some other time; it's my replacement for Photoshop and I really like it. But today, I want to say nice things about Optics Pro 10.

Might seem an odd thing to admit, but I don't really want to use Optics Pro. It can't hold a candle to Lightroom for browsing and managing images. And it doesn't support layers (like Perfect Photo Suite) or much in the way of selective editing (like Lightroom, Nik and Perfect Photo Suite do). I'm able to get what I want from most of my images using Lightroom, or Nik or Perfect Photo. So most of the time, I don't need Op…

Why I switched from Lightroom to Aperture

Read today an excellent article, "Why I use Aperture instead of Lightroom," by Mel Ashar; it's posted at the Aperture Expert blog edited by Joseph Linaschke. Ashar, a landscape and architectural photographer, provides a useful catalog of some of the reasons Aperture is a strong choice for photographers who use Macs. He focuses on the file-management advantages of Aperture that arise from the fact that Apple controls an entire file ecosystem, comprised not just of Aperture, but of iCloud and the file systems on both Macs and iOS devices (iPhone, iPad).

Now, notwithstanding the advantages Ashar enumerates, the consensus seems to be that, Aperture as a photo processing app lags way behind Lightroom. I disagree with the consensus. In fact, shortly after the public beta of Lightroom 5 became available, I started looking again at Aperture and this time I really gave it the old college try. To my surprise, I discovered that I liked it. I liked it a lot. So, instead of upgrading…
