Perspective Correction

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.

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.

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.

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.

In Camera Abstract

5D Mk III, EF100 f/2.8L IS Macro, f/11 at 1/6 sec

Larger Image

Having fun with abstract images, shooting a grove of Alder on the way up to Bridal Veil Falls I have a whole series now on abstract trees, its a little different each time I shoot, because of light, but it can be a fun exercise trying to get the right amount of camera movement to make the image blur just the right amount.

Getting the shutter speed right is key to getting this type of abstract image, I shot at f/11 to slow the shutter speed down in to the range of 1/6 to 1/4 of a second.Then I moved the camera either up or down as I depressed the shutter button, trying to keep the motion of the camera as parallel to the trees as I could. The green just comes from the surrounding foliage.

Lytro Illum

Lytro announce a new version of their Light field camera, with a 30-250mm f/2 lens, that's right f/2, the technology is very interesting, but their last camera and sensor proved only a gimmick from a photographic standpoint, this may change that, they look like they may have something on their hands this time around.

 

From the Lytro site:

Product Features

Sensor

Capture a deeper picture.

LYTRO ILLUM’s 40 Megaray customized sensor, with Lytro’s patented microlens array technology, unlocks the ability to capture the color, intensity and direction of the light rays flowing into the camera. This allows you to create imagery on a truly experiential canvas. By capturing and harnessing the power of light field, photographers can portray not just a cross-section of reality, but an authentic, interactive window into their world.

• Custom-designed 40-megaray light field sensor
• 8x optical zoom lens (30mm-250mm equivalent)
• Constant f/2.0 aperture across the entire zoom range
• 1/4000 of a second high-speed shutter
• Extreme close-focus macro capability
• Combination of tactile-controls and smartphone-class, articulating touchscreen
• Dimensions: 86mm x 145mm x 166mm; 940 grams
• Hot shoe supports all leading flashes

It needs to be ergonomic and fill a niche, or carve out a place of its own with something beyond mini video, which is what it appeared to be before.

I did not see a place that it would be useful before, lets see if they are bringing more of a game changer this time around.

New Sigma 50mm f/1.4 DG HSM Art lens

Sigma 50mm f/1.4 DG HSM Art lens

I never would have thought I would say this just a year ago, but Sigma has smartened up and now designs good lenses, with their new ART series.

DXO Test's show conclusively that it out performs most other lenses.

 So this only applies to the ART series of lenses, but its a good sign from a company known for producing marginal lenses, if I wanted to put a 50mm lens on my 5D today, it would be the Sigma.

I have always wanted to go back to Yosemite, but I was kind of disappointed on this trip, perhaps I have seen to much of it in pictures ? at any rate the next time I return, it will be to the upper part that is less traveled, Tuolumne Meadows above Yosemite Valley, it has the beauty, less crowds and the wilderness feel that the lower valley lacks, a winter stop in the lower valley might be nice, if there was plenty of snow.

Upper Cathedral lake and the entire upper basin would make for a great trip on the way over to the Eastern Sierra and a trip up in to the Whitney Portal and Convict lake.
