A Nikon lens with double vision

Published by Bruce on June 25, 2009 in Photography. 4 responses

I was most disappointed with the images I obtained during our recent trip to Florida. Many telephoto shots appeared out-of-focus despite the well-regarded image stablilization (vibration reduction) built into the Nikkor 18-200mm f/3.5-5.6G IF-ED AF-S VR DX attached to my new Nikon D90 body on it's debut outing. As was my habit, to protect my investment the lens was fitted with a screw-on skylight filter. I couldn't believe how poor my shots were when viewed on a 24" display: Was the camera (still in warranty) malfunctioning? Had my photographic skills regressed? Could something be wrong with the (now out-of-waranty) lens? Why was the centre of some images sharp, with progressive blurring or even 'double vision' towards the peripheries? These were questions for Nikon to answer.

Geotagging comes to Nikon ViewNX

Published by Bruce on February 9, 2009 in Quicklinks. 0 responses

Nikon ViewNX 1.2.0 is a free download (56.6MB .dmg) and doesn't require a Nikon (e.g. works with iPhone images). Manual geotagging is limited to placing a pin on a Google Map (you can't search the map). ViewNX recognizes automatically geotagged images (embedded at capture, added via a track logger, etc.) and handles geotagging of Nikon's raw (NEF) format as well as JPEG. To view location metadata (indicated by a globe icon), select an image and click it's pin to reveal an info window. Reverse geocoding is not performed and any existing IPTC headers are ignored.

An ABC of geotagging photos on the Mac

Published by Bruce on March 5, 2008 in Photography. 57 responses

This article considers geotagging photos from a Mac perspective, looking at automatic and manual methods, and explaining terms such as data loggers, track points, waypoints, and routes. It lists OS X software options for connecting to data loggers, converting track log formats, geo-locating photos, and writing that data to EXIF for both raw and JPEG images. It also covers the importance of time synchronization, what you can do with geotagged photos, workflow, choosing a data logger and controlling it from your Mac.

In the shadow of Mt. Doom

Published by Bruce on January 28, 2007 in Photography. 0 responses

We end this month in New Zealand with a sense of achievement: we walked the Tongariro Crossing without significant pain nor injury. We had good weather and got some great photos of the beautiful volcanic landscape. Our 18.6 km walk began early morning in the shadow of Mt. Doom, as Ngauruhoe is now popularly known following its role in Peter Jackson's Lord of the Rings. In the bright sunlight at altitude, capturing well-exposed images of the dark landscape required extra care to avoid blown highlights.

Clean up your image

Published by Bruce on January 8, 2007 in Photography. 0 responses

Every time you swap a lens you risk dust getting inside the body of your SLR. It can settle in front of the sensor and appear in every image that you take thereafter as an indistinct spot (dust on the lens apparently makes for a more defined dirty spec, although it depends on aperture). While many of these artifacts can be effectively dealt with using Photoshop's invaluable healing brush (working at 100% image size), sometimes they fall on an image zone that makes correction difficult. At some point they become to numerous to ignore; that's when I decided to get some CCD housekeeping organized.

A horse of a lens

The AF-S Zoom-Nikkor ED 18-200mm f/3.5-5.6G IF DX VR is a great lens (if you can find one). This isn't a review (for that, see here or here), but I'd like to share one aspect of user experience with you.
