Perspective Correction

Larger Image

Image: 5D Mk III, EF 24-70 f/2.8L II, 24mm, f/11 at 1/60 sec.

Perspective correction is something we come up against whenever architectural elements are the subject matter of a photograph. This image of the lighthouse in Mukilteo is a good example. Looking at this image subjectively some will say the image should be fully corrected and some will say it would look un-natural that way. I believe a certain amount of distortion is acceptable and appears more natural.  

Other issues with correction are reduced resolution due to crop and sharpness loss from the correction itself, for these reasons I always try to minimize distortion correction, the original size of the image was 5760 x 3840 and the fully corrected image is 5399 x 3712, not a huge change. One last thing to keep in mind is your field of view, the fully corrected image lost a lot of foreground detail (flowers, pathway).

Photokina 2014

LX-100

This is the camera that looks most interesting at Photokina this year, it is a well specked compact camera, a 4/3rds sensor with a fixed 24-75 mm(equivalent) f/1.7 to f/2.8 lens. Could very well be the first 4/3rds camera I get to test, well 2nd after the GM1, anyway it should be a great little camera.

Not cheap at around $900 but probably well worth it, we'll see what the gang at DPreview have to say, I look forward to it. 4K video is pretty cool too, I want that in my next camera.

Architectural Perspective




Its not always necessary to include the entire subject in your photo, sometimes an image takes on a life of its own when you don't include the expected. 

I enjoy the ability to shoot both Seattle and San Francisco these days,  and its given me a new vision of city scenes. Finding the individual subject and the abstract meaning in those subjects.

City View

Image: 5D Mk III, EF 24-70 f/2.8 L II, 70mm, f/10, 20 sec.

The Bay Bridge and San Francisco viewed from Treasure Island, probably one of the best, but also most obscure locations to view the city. Up off the beach on a crumbling hillside, on Treasure Island, not a very safe place to be putting a tripod down, especially after it gets dark and you need to traverse the hill with a headlamp.

Do we still need a tripod?

Image: Fuji X-T1, XF 18-55 f/2.8-4.0, 23mm at f/5.6, 1/5 sec,
hand held at ISO 6400.

The answer is a definitive maybe, it depends what your after, just fun images like the above one, then no, a large format print for your wall at home, that depends on the light. Hand holding a camera in low light takes a lot of practice to get sharp images and you still need high ISO's to get there, so we still have a ways to go.

Cameras like the X-T1 with image stabilized lenses are getting us close though, even with the slowdown in sensor technologies, its just a matter of time. However there are images that will always require a tripod, long exposure's just can't be reproduced in Photoshop and I'm a big fan of long exposure's, whether they are a few seconds or 20 minutes.

I like shooting Jets on this corner, the runway stripes make for an
 interesting reflection on the belly of the plane.  Here's another

Somehow this blog seems fitting as I move in to a new career on the professional side, going from an Aerospace Design Engineer at Boeing to a Camera Field Test Engineer with Amazon.

 I have to hand it to the marketing folks at Air New Zealand, this is one fine looking airplane.

My next blog should be coming from the Bay area, somewhere near Sunnyvale. Stay tuned.
