Embedding a Zoomify File

I have played with the Zoomify files a few times before. Then I found a way to get a Zoomify file output in HTML5 format rather than Flash. Since so many people are on mobile devices today and plenty of them don’t use Flash, having the new format was necessary to make the output usable widely. I didn’t like the idea of a new page opening up though. Taking people off your page can mean that they don’t come back. Fortunately, I found out how to embed this in an iFrame. Those of you that are web savvy will know all about this stuff but I didn’t. However, messing around with some page code and suddenly my stuff is embedded in the page above. Pretty cool. Feel free to zoom and pan around the Nellis flightline!

High ISO Raw File Size

Leave a Reply

On my previous camera bodies I had occasionally shot at very high ISO settings as a result of the lack of light. I had not paid a huge amount of attention to any secondary effects of doing so. My current cameras had a work out in some very low light when I decided to test them in some rather unfriendly conditions. When I was at home, I was running some disc backups and I found I could not get the normal number of files onto a single disc. A quick bit of investigation and I could see why. The high ISO shots had a significant increase in file size. As I understand it, RAW files, while containing all of the data from the sensor, do have an amount of compression applied. I imagine that the noise inherent in high ISO shots means that the compression is less effective as there is so much variation across pixels. As an example, a shot at ISO 320 will average at about 22Mb. The shots at ISO 51,200 are coming in at over 30Mb. At ISO 204,000, the files can hit 40Mb. That is quite an increase! Something to keep in mind when planning to shoot in very low light conditions.

Can 700mm Reach Into the Cockpit?

Since changing camera bodies to something that is full frame, one of the things I have been pondering is what I will notice about the reduced reach that I will get with my current lenses. Obviously there will be a change. So far it has only really resulted in me changing when I press the shutter since I still work based on what I see through the viewfinder. While we were out on the range at Hawgsmoke, the jets would carry out a strafing run and then pull towards the range tower where we were located. Sometimes they would be really close.

I had decided to try putting a 1.4x tele convertor on the 500mm to compensate for the larger sensor size. This worked well for a number of the shots but, when the jets pulled overhead, it was a touch too much! These shots are not cropped. They are really that close and you can see exactly what is in the cockpit.

Lightning Photography

When I shot film I had a go at shooting lightning a number of times but never with any success. I would try and react to get the bolt but it was always gone. When you are using film and having a very low success rate, things get too expensive. Consequently, I gave up on it. The move to digital opened up a new range of possibilities.

My new approach doesn’t involve much skill (but then neither does using an electronic trigger). I set up the exposure to have a reasonably long shutter speed. Then I put the camera on continuous mode, plug in the cable release and lock the shutter open. Then the camera takes a steady stream of shots. Of course, when there is a slight gap between shots, you can imagine when the lightning will strike.

I used to shoot a lot from the apartment in Chicago. Set the camera up and go and do something else. Unfortunately, the heavy rains that would accompany the storm activity could result in the sky glaring out but you still had a chance. Some of the shots were okay and every once in a while you would get a really cool outcome. The Trump Tower was next to us and it would be struck occasionally but it was too close to get a good look at. You could hear it though!

FedEx 757 and Oh So Close

Leave a Reply

I have posted before about taking photos from airliners of passing jets and using Flightradar24 and the wifi connection to try and get a shot. On this trip I had two good opportunities that I knew about. The first was a 757 operated by FedEx. I could see it coming using the app. It was apparently not going to be a close pass but it was going to be within range. I saw the jet show up and shot a sequence of it as it came by. The shots were okay given the idea of shooting through windows. A better chance came with an American 737. It was going to be really close to our flight path. Actually, it was really close. Unfortunately, it came right under us. I saw it flash by but I only got shots of engine nacelles and wings of our own jet. Oh so close!

Black-Footed Albatross

The albatross is a pretty amazing flyer. A large wing span and a very high aspect ratio make for an efficient cruiser. The wandering albatross is perhaps the most impressive with its ability to cruise the southern oceans for months at a time. I haven’t had a chance to go south to see one of those. However, while out in Monterey Bay on the whale watching trip we did have an encounter with a black footed albatross. It might be a bit smaller but it still has the same characteristics. Great efficiency and the ability to soar about the surface of the water with ease. What a cool bird.

Southwest Evasive Maneuvers

This was not an aircraft photography trip. I was taking a walk along the shore at Hayward Regional Park. It is a place with lots of wildlife and views across the bay. It is also near the approach to Oakland so I did have the chance to take aircraft pictures if I wanted. That wasn’t the goal though. It didn’t stay that way though. The approach to Oakland involves flying right by Hayward Airport. Hayward has a lot of general aviation traffic. The spam cans are intermixed with some corporate jets.

What caught my eye was the incoming Southwest 737 and a departing Cessna CJ M2. The CJ took off and entered a climbing left turn. This put it into the path of the Southwest 737. I don’t know who was at fault in this. Was the Southwest jet too close, did the CJ pilot break his cleared departure profile or should Hayward tower never let him go? I don’t know. Whatever the reason, they were heading towards each other.

I also don’t know whether the Southwest crew saw the CJ first or if the TCAS gave them a resolution notice. Whatever happened, they took some pretty dramatic avoiding action. I imagine it felt pretty interesting from inside the cabin. They gained good separation and everything was fine. At first I thought they were going to try and get reestablished on the approach but cooler heads prevailed and they cleaned up the jet and went around. After some time to let the heart rate fall, they appeared back on the approach for a more conventional approach. All ended well. I wonder how the conversations went after landing.

Breaking up the Wreck

Leave a Reply

A little while ago I posted a picture of a sailing boat that had wrecked on the breakwater at the marina on Coyote Point. The next time I was back there, I guess I had timed things well. The boat had been pulled ashore and a guy was busy breaking it up. He used the front scoop of a backhoe to break the hull up. Obviously it was beyond rescue. He would pull sections off and then drop them in a dumpster. As he broke it up, more of the interior would be visible. The fiberglass is quite flexible so he had to work to actually break it sometimes. However, there was only going to be one winner in this contest.

Spooky Metroliner(ish)

If I hadn’t been with Joe who is a bit more familiar with the regular movements at Tucson International, I would not have been too interested in this aircraft. It looked like a pretty standard C-26 to me. However, Joe was quick to see it and told me it is one that he had not seen move (I can’t recall whether this was ever or just for a long time). Apparently, the turret under the fuselage is for surveillance activities of a spooky nature. Why it was moving on this day (was it watching me?) I have no idea. I was just glad that, rather than dismissing it as I might have done, I found out it was a little different.

No Need to be Koi

During our walk around the Chicago Botanic Gardens, we walked across a couple of the bridges over the lakes. The lakes are home to a variety of wildlife including plenty of koi carp. I guess they are pretty smart fish as the appearance of a few people seems to attract them rapidly. I guess they get fed enough times to learn. So much for fish having short memories.

These guys showed up in force. They came up from the depths so, for a while they weren’t apparent but then suddenly their form would solidify. They would drift around making it look like it was a coincidence but soon they were right underneath us. Obviously this was no coincidence at all.
