Unidentified Flying/Crashing Object

// February 23rd, 2014 // 10 Comments » // Photography

Took this picture at 6:39 AM – no idea what it was (meteor?), but it looked pretty spectacular through binoculars. It was visible for a good ten minutes before the Sun got too bright.

Update: I’ve uploaded the original pictures with exif data, including a zoomed-out version for perspective. 23-29 in the series are almost identical shots.

GPS coordinates, if it helps: 12.981133, 80.259994

HDR pics from Dubai

Got some decent touristy shots over the last few days, this is the first set. Cant wait for the Dubai IndiBlogger Meet today!

Windmill

Standing at the door of a moving train, one leg braced against the doorframe, the other on the steps, camera strap choking my neck. What surprised me about this picture was that I wasn’t even looking in the viewfinder. I was more concerned about keeping my head from being knocked off by an electricity pole!

Experiments with HDR

I didn’t really spend much time tweaking these… got some good originals though so will get better HDRs when I have more time to play with them.

Power is beauty: The White Tiger

// June 16th, 2009 // 14 Comments » // Photography

This was another trippy trip with the Patels. We headed off one Sunday afternoon to the Vandalur zoo, and for once – all that walking was worth it cause it ended with this White Tiger putting on a great show for us!

Love those greenish-blue eyes!

I didn’t know these buggers liked leaves. Soon they’ll develop longer necks.

Yummy – humans! (I’m sure we’re not as tasty as he thinks we would be)

Now that’s a profile pic – I don’t know how he doesn’t bite that tongue with his own teeth. I can picture myself running for my life and the tiger thinking “relax dude, I was just yawning”.

I so wish we could have thrown a cute little deer in there and watched it be hunted down.

Rest of the pics on Flickr. A much more descriptive post about this tripĀ  (including the battle of the apes) on Anwin’s blog.

Still looking for that perfect HDR

// November 19th, 2006 // 2 Comments » // Featured, Photography

I’ve been trying my hand at High Dynamic Range (HDR) images ever since I saw this slightly over the top one at Flickr. After many, many messed up attempts I’ve finally managed to get a few decent ones at Vellore last weekend:

If you aren’t familiar with HDR photography, you probably think these images were run through a hundred photoshop filters. Actually, HDRs are a result of combining three separate photographs of the same scene, but with different exposures. When the three images are combined, you get all the highlights and shadows in great detail. Click here to see the three original exposures of the Vellore fort, followed by the final HDR.

The trick with getting decent results is knowing how far to push the final output HDR. If you go too far, it would end up looking like this. I liked this shot on Flickr, think he/she got it just right. This night shot is nice as well. For some tutorials on taking HDRs, go here, here, here and here.

576 Megapixels?

// October 23rd, 2006 // No Comments » // Featured, Imaging, Photography

No, it’s not a camera you use to make blowups that can be seen by passing aliens. According to this article on clarkvision.com, it’s the resolution of the human eye when compared to a digital camera.

The eye is not a single frame snapshot camera. It is more like a video stream. The eye moves rapidly in small angular amounts and continually updates the image in one’s brain to “paint” the detail. We also have two eyes, and our brains combine the signals to increase the resolution further. We also typically move our eyes around the scene to gather more information. Because of these factors, the eye plus brain assembles a higher resolution image than possible with the number of photoreceptors in the retina. So the megapixel equivalent numbers below refer to the spatial detail in an image that would be required to show what the human eye could see when you view a scene.

Based on the above data for the resolution of the human eye, let’s try a “small” example first. Consider a view in front of you that is 90 degrees by 90 degrees, like looking through an open window at a scene. The number of pixels would be
90 degrees * 60 arc-minutes/degree * 1/0.3 * 90 * 60 * 1/0.3 = 324,000,000 pixels (324 megapixels).
At any one moment, you actually do not perceive that many pixels, but your eye moves around the scene to see all the detail you want. But the human eye really sees a larger field of view, close to 180 degrees. Let’s be conservative and use 120 degrees for the field of view. Then we would see
120 * 120 * 60 * 60 / (0.3 * 0.3) = 576 megapixels.
The full angle of human vision would require even more megapixels. This kind of image detail requires A large format camera to record.
