Xperia Z1

I do believe that the best camera is the one that is always with you.

More than a decade ago, it was my Lomo LC-A because it is compact enough for me to bring it with me to most places. Today (in 2014) it is the Xperia Z1. I am so glad that we now have smartphones which are equipped with high-resolution sensors. The Xperia Z1 camera sensor packs 20.7 megapixels in 1/2.3-inch area. This sensor is among the largest in the smartphones’ market and should promise low noise (but not really…) and better bokeh. The phone also has a dedicated shutter button with half-press ability — something I like very much.

The default operation mode is Superior Auto which means the user just needs to compose and trigger.  The Manual mode on the other hand offers a little more flexibility to the user for EV compensation and setting of WB. It does not provide control/access to the shutter speeds and lens aperture (aperture seems to be fixed at f/2 in all the EXIF data I have checked for both Auto and Manual modes). Instead, there is a Scene selection. Also, full resolution 5248 x 3936 (20.7MP, 4:3) is only available in the Manual mode.

Scene seletion in “Manual” mode

 

Although I prefer having some manual controls in my cameras, I seldom use the Manual mode. I stick to Auto most of the time because:

  • Noise at full resolution or 20.7MP is more pronounced
  • Smaller file obviously, with Superior Auto which locks max resolution at 8MP
  • 16:9 in Superior Auto crops out the soft corners reported
  • The phone doesn’t remember the mode which I last used! Each time I start the camera app, it goes to Superior Auto!

Besides these two modes, the camera app also accepts add-ons developed by Sony and third parties (e.g. Evernote). I rarely use any of them except for Timeshift burst. They’re downloadable from the Play store.

Below are sample photos, directly from the camera (unedited) but resized, shot in either Superior Auto or Manual and all handheld. You can probably tell which mode is used from the aspect ratio. Resized images often reduce the effect of noise (one conclusion – most phones are fine if you use the photos for web). The lens according to the EXIF data, has 4.9mm focal length. I read this is equivalent to 27mm (FF/35mm).

To conclude, the camera produces sufficiently good images. With some post processing (noise reduction, sharpening, adjustments of shadows & highlights), the resized images should look great for web (or facebook, etc).

While the camera in your smartphone is not going to replace “real” cameras anytime soon — it should still be your best because you have it with you all the time — unless if you have dSLR with you all the time too.

The Enclave

The morning sun gloriously painted the buildings golden but I was unable to reproduce this straight out of the camera.

I shot this in JPEG and post-processed in Lightroom to add gradient filter (teal corners) to produce this.

Blue Hour at the Port

Woke up early for this shot. This was taken from one of the south-facing blocks in the Engineering Faculty of the National University Singapore (NUS).

This is the Pasir Panjang Terminal, part of Port of Singapore.

The Port of Singapore includes terminals located at Tanjong Pagar, Keppel, Brani, Pasir Panjang, Sembawang and Jurong. They can accommodate all types of vessels, including container ships, bulk carries, ro-ro ships, cargo freighters, coasters and lighters. The Pasir Panjang Terminal (PPT) handles mega container vessels of 13,000 TEUs or more with quay cranes that can reach across 22 rows of containers. Remote controlled bridge cranes allow each operator to handle up to six cranes. [Source: Maritime and Port Authority of Singapore]

Hello World

It was sometime in late 90’s when I first “blogged”. It was all manual and tiresome because there were no LifeJournal nor Blogger. It was also more like a tweet, because I don’t have much to say. Having to deal with all the HTML tags and photo uploading via FTP, it didn’t take long for me to stop.

Now I just want to be a regular user. Also because WordPress had gotten so friendly and at the same time so complex for me to hack. Installation is a breeze now that my webhost (referral) just requires a mouse click from me.

I’m going to start with this photo, taken during the Christmas-NY break weeks ago. It was moments before dawn, and among the first few shots taken once I’ve my tripod set up.
