My K20D dead

With years of abuse, my K20D finally dead a few months back.  Well, it's not dead. It's very strong indeed, except I have broken the top cover and resulted in malfunction of the mode dial and light-meter switch, which makes the multi-segment meter and P mode gone.  Not a very big deal for me.

However, another problem make me put away the K20D in the deepest corner of my camera box forever:  it's a strange horizontal line on EVERY picture I took with K20D, jpeg or RAW.  At first, there was a dead pixel on every pic.  Easy fix with Pentax because K20D comes 'pixel mapping' function, handily in the setup manual.  It turns out to be a disaster:

INSTEAD OF JUST ONE DEAD PIXEL, A HORIZONTAL LINE TOGETHER WITH MAPPING ARTIFICE APPEARS ON EVERY PIC.  (See below pix)



While dead pixel can be easily fixed in Lightroom, the mapping artifice is very troublesome because I have to fix it manually.  

My K20D served a good 70,000 shutter count. So I just let it R.I.P. in my camera dry box. Amen,

I get a used K5 instead.

SNAP of the Symmetries



Life isn't perfect, so I love to find some perfection with photography. While it may be difficult to get other aspects in perfection, perfect symmetry is easy to achieve, especially with the easy cropping of digital photos.

This one is totally unaltered, not even cropping.

scaffolding and blue sky



With a very cheap digital camera, the image quality is rather low... if you judge from a pure photography point-of-view. However, for screen view, it may have some special mood.

Just tuned a bit of the curve, and add polarization for added surrealism.

Immortality inside the showcase



The intriguing contrast between the immortality inside the showcase; and the man in the reflection who have to suffer the aging as time passes by. Which one you really prefer to be?

Thanks to the convenient curve function in Aperture, I can life-up the shadow conveniently without going to PS.

reflection of a closed gate



Another old snap shot with Olympus 4040. The highest sensitivity is only ISO 400, so shooting at such condition is a real challenge. The technicals of this pic is bad: grainy and shake. But I like the mood.

Changed to b/w in Aperture.

Subdued human, majestic mascot



Mascot in showcase looks majestic; while real human humble and subdued before the temple.... how ironic!!

Angel's wings?



Interesting light and reflections are everywhere in the cities. We just have to pay attentions to find it out.

This is an old snap with Olympus C4040, a 4MP ISO 400 DC. The pic is noisy; the cam focus slowly, but I have been snapping around with it for almost 4 years. In snap shots, camera is really not that important. The only thing matter is: you just need to shot more.

"X" / On Zone Focusing




Another non-finder snap by P&S DC. Since I am doing a lot of non-finder street quick snap, the focusing speed of the DC is very important. I was and still using the Fujifilm F10, and the response time is quite good.

For non finder snaps, the old masters will use zone focusing (or pre-focusing), ie. use relative small aperture eg. f/8, and pre-focus the lens to something like 3 or 4 meters, and most common subject will fall into the depth-of-field...... It sounds complicated, but it's actually very simple and basic photographic skill. This technique is getting lesser attentions, and I guess there are a few reasons behinds:
- Modern cameras have very fast and reliable AF system, so there is no need for zone-focusing (sorry for Pentax, the K20D + DA21 combo sometimes let me down in non-finder shots).
- The depth-of-field idea is actually an approximation: ie. the photo will 'looks' sharp for 'reasonable' viewing distance. Reasonable means you are looking at a 4R photo at around 25cm distance. So if you scale-up your photo 100% on screen, it's not sharp at all. Too bad most people do zoom-up on in computer to closely look at the photos, and zone focusing just don't work for this kind of critical scrutinization.
- MOST IMPORTANT REASON: most modern lenses do not have a depth-of-field scale... so there is no way to use the lenses for zone-focusing.

Silhouette of dead tree



Another tree branches photo against blue sky. With the direct midday sun as the background, I need to carefully avoid flares even with the legendary Pentax SMC, well, that may be impossible with N or C lenses. Of course, you have to remove any filter in-front of your lens.

Strong vignetting is added in post-processing.

A beggar outside the Bank Centre



The original shot was in color mode, and turned to monochrome and add some vignetting.

With the new retouch brush function in Aperture 3, I tried to brush away the saturation of the background, and just retain the color of the subject (the beggar). The result is interesting, but I don't like it. So I just keep with the basic processing.

Branches



Trees are everywhere, and similar picture can be found everywhere. I don't know why I love to take photos of branches. I just do.

Thanks to Apple bringing the curve function to Aperture 3.0. The Aperture 2 has a 4-point Level function, but it's not as good as the Curve command.

Show Window



I like to snap show windows. I always imagine the mascots inside the show windows have their own cognition, they are just not moving. They don't don't feel sad being confined in the crumble space of the showcase, but mocking the human being outside stupid enough to chase materials and fame that don't last....

In this snap, the mascot seems mocking the high-rised office building, and the people inside. The triangle shape of the mascot is also a strong design element in the frame.

Digitally alter to monochrome with orange filter setting (to further isolate the yellow dresses from the greenish background), and added selinium toning effect.

What are you looking for? / On Cross Processing



With the new Aperture 3, there is a lot of different 'presets' of common digital effect, Selinium tone is one, and this one is Cross Processing. Aperture will show a quick thumbnail preview of the effect when you mouse-over on different presets, so you will know how the image will look like before clicking on it. It's real fun!

This Cross Process effect (there are two different cross process presets in Aperture 3) resembles the E-to-C effect in the film age. "E" refers to E6, which is the Kodak process for color reversal slide films; and "C" refers to C41, the Kodak process for color negative films. People actually get this idea by accident: some people mistakenly used the C41 to process color reversal slide, and they find the processed slide to be of high contrasted and mis-colored. Some people like the surreal feeling, and intentionally use E-to-C as a creative tool of photography.

It's the old days. Now we have digital processing, and you don't need to know a lot about technical to try different color effect. Many new programs also have this kind of effect build-in, so all you need to do is one mouse click. HOW GOOD IT THAT!!

"Passed by...." / On Selinium Toner



An old snap with slide (yes, the expensive slide). This shot was shot on ISO100 slide, handheld at approx. 1/4s, scanned with film scanner, and digitally altered to monochrome with Selinium tone.

Speaking of Selinium tone, it is actually more than an artistic style.

In the good old days of black-and-white photography, the photo paper was treated with chemicals. Because of the acidic nature of the 'fixing' process, b/w photos are prone to color fading over time, particular when photos are not washed in running water long enough. For additional stability of the photo-print, an additional step called 'toning' is often used. Most toner will alter the color of the print, e.g. Sepia Toner will add a brown tone to the print. Selinium Toner is the most stable toning chemical, and often used in gallery display.

The Power of Light



The beauty of nature is everywhere. You just have to look for it, and you will find it.

Only minor adjustment in curve.

Dawn at somewhere in China



An old snap took years ago.

When I snap, sometimes I will stop and wait for some interesting elements to come-into the frame; and this was one of these shots. Motorcycle is very common in this part of China, and the bike in this shot reflect my impression to this city more accurately.

It's a handheld shot, and I pushed the sensitivity way up to ISO 1600.

And this is Shantau, Guangdong.

The morning market



The market was not yet opened. Sunlight shines through the canopies of kiosks, casting different shades of shadows. I was on my way to work, and snap this with a P&S camera.

Took with color negative film, scanned by film scanner, digitally change to monochrome.

Buried? Still shines!



Deeply buried in concret, the barrel still shines with it's color. Ain't that inspiring?

Vignetting was added in digital processing to enhance the subdue mood of the scene.

Locked



I like locks recently, for unspeakable personal reasons.

Digitally monochrome with default setting in Aperture.
