Implementing Video

I just got a Flip Mino HD to play with and am thinking of doing some video on the upcoming trip to Spain like I did in Belgium over Christmas. My first thought was to simply host the videos on my web site and embed them. I had this working more or less with the Podpress plugin but for some reason it’s gone all wonky on me.

In my search for options I found a variety of plug-ins for self hosting video, but they are convoluted and not one offers what I really need.

The other option was to upload to one of the video sharing sights and snag the embed code for publication here at baldheretic.com. Youtube doesn’t allow you to embed the HD version of your video into your own blog so that’s a waste. I was turned on to Vimeo by John Winters (aka @obscura) and it is impressive. The problem is that you are only allowed to upload 500mb a week, which is fine but they only allow ONE HD upload a week which is not so great. You can upgrade to Vimeo Plus for a fee of $59.95 a year. This account allows for 5 gigs of uploads in a week and unlimited HD uploads are included in that.

Kind of overkill for my purposes and too pricey.

I also checked out Flickr Video which is available to Pro account holders like myself, but they limit your videos to 90 seconds with no option to go longer. The call it “a long photograph.”

In my quest I stumble upon a post by WordPress founder Matthew Mullenweg where he was showing off a movie made from tilt-shift photos he had taken.

Doing a little digging I found out that if you have a pemium account at wordpress.com you can upload videos of many different formats and the site will crunch and convert and allow you to embed them rather seamlessly. The premium account is only $20 a year for 5 gig of storage. The cool thing is that once you upload the video you can then grab the embed code and place it in the blog of your choice making this a reasonable alternative to Vimeo for me personally.

It irks me that this functionality is not available for those of us who self host our own WordPress blogs. I suspect it has do with whatever is needed on the back end to process the videos, but still. I bet it could be implemented without much fuss. We’ll see what comes down the pike in the future.

In the mean time I have paid Mr. Mullenweg his thirty pieces of silver and acquired the upgrade. I do like the quality of the video.

If Matt reads this I would like him to know that donated wordpress.com account to Technology Bytes would be a tax write-off. Just wanted to put that out there.

BUG

We went for a walk on Saturday down by the bayou just to get out and get a little excercise. Of course I had the camera in tow. Not a lot of photo opportunities, but Cynthia spotted this guy on a flower no bigger than a pinky fingernail. I’m stiff today from squatting down and trying to hold the camera still as the wind blew my subject to and fro.

It looks very much like a Crane Fly (aka Mosquito Hawk) which we see all the time in and around the house. But this guy is much smaller and has a probiscus rather than mandibles. My guess is he’s either a juvenile Elephant Mosquito or just a plane old male mosquito.

This pic remonds me of the album cover of Jeff Wayne’s Musical Version of The War of The Worlds

On a side note, there’s a 30th anniversary tour in the works which (sadly) doesn’t look like it will make it here to the U.S.

This shot was done with a flash from above.

Macro Mothra

Best shot of the day at the Cockrell Butterfly Center was of this moth as I was leaving.


Camera: Sony DSLR-A700
Exposure: 0.008 sec (1/125)
Aperture: f/9.0
Focal Length: 100 mm
Exposure: 0.00

There was a little daylight shining right on him so I shot with fill flash which allowed me to take advantage of the natural light for the majority of the illumination.

Check it out when we zoom in a little bit.

The detail is phenomenal!

It’s pretty amazing and worth checking out.

Sony SAL-100M28 – A Modest Review

I’ve always been fascinated by macro photography and it just so happened that I was investigating options for a dedicated macro lens without any real intention on adding one to the arsenal until I fell prone to poor impulse control again.


Above photo was shot for fun and treated with a little HDR style processing to enhance detail.

In my research I read about the Sony SAL-100F28 along with Minolta AF 100 F2.8 Macro D which is the out of production predecessor to the Sony. And while the Minolta is less expensive than the Sony when you can find a good copy on the secondary market (Ebay, Craigslist, etc), I opted for the updated optics and mechanicals of the Sony along with a warranty.

Don’t get me wrong, the vintage Minolta glass has been widely praised. I even own the legendary Minolta AF 70-210 F4 (Beercan) lens and love it dearly. It’s just a crap shoot sometimes when you buy used technology from the 80’s and I was willing to pay the extra dollars for the Sony. Besides, immediate gratification was in play.

I also considered the Sony SAL-50M28 but decided I needed the 100mm reach over the 50mm to be able to get the shots I envisioned.

A medium sized and lightweight lens, the Sony SAL-100M28 is not cumbersome in the bag or on the camera. Being fast (f/2.8) and a prime lens, it appeals to my fast lens snobbery.

Aside from a few shots taken of Dooley and my own eyeball and such, I hadn’t really had a chance to really take this lens through its paces. Cynthia suggested The Cockrell Butterfly Center as a possible testing ground and having the day off yesterday I decided to make the trek to the HMNS compound to give it a whirl.

It’s worth noting that the Cockrell Butterfly Center is hot. They keep it hot to keep the butterflies alive, which makes sense. Having been there before I dressed comfortably and wore a head scarf and remembering my Hitchhiker’s advice I brought a towel.

The Hitch Hiker’s Guide to the Galaxy has a few things to say on the subject of towels…

“A towel, it says, is about the most massively useful thing an interstellar hitchhiker can have. Partly it has great practical value – you can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapours; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a mini raft down the slow heavy river Moth; wet it for use in hand-to- hand-combat; wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindboggingly stupid animal, it assumes that if you can’t see it, it can’t see you – daft as a bush, but very ravenous); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough.

More importantly, a towel has immense psychological value. For some reason, if a strag (strag: non-hitch hiker) discovers that a hitch hiker has his towel with him, he will automatically assume that he is also in possession of a toothbrush, face flannel, soap, tin of biscuits, flask, compass, map, ball of string, gnat spray, wet weather gear, space suit etc., etc. Furthermore, the strag will then happily lend the hitch hiker any of these or a dozen other items that the hitch hiker might accidentally have “lost”. What the strag will think is that any man who can hitch the length and breadth of the galaxy, rough it, slum it, struggle against terrible odds, win through, and still knows where his towel is is clearly a man to be reckoned with.”

Ok, I wasn’t hitching a ride across the galaxy, but I did need to be able to wipe the sweat from my brow as I plunged into the macro-verse. It was a wise choice.

It should also be noted that when changing lenses while dripping sweat you want to be extra careful not to drip into the sensor while the lens is detached. I dodged this bullet with an uncharacteristic display of forethought.

I don’t have a macro flash (yet) so any flash photography was going to be done using the built in flash of my A700. Shooting with a flash allows you to shoot at a slower aperature which increases the depth of field.

Shooting with a flash does make shooting with auto-focus much easier. But as I have mentioned previously, I prefer to shoot without a flash. This does present its own set of challenges. Faster aperture means shallower depth of field which means it’s harder to gain and maintain the focus of such tiny objects. If you breath (in or out) your subject moves completely out of focus or you focus too much forward or aft of your subject.

Since good macro photography is usually done using manual focus, a tripod or monopod is recommended. I did not bring one on this trip.

I discovered a technique where as I allowed myself to ever so slowly and ever so slightly pull back from the subject as I fired at full on 5 frames per second after achieving focus. The results are very satisfactory.


Exposure: 0.006 sec (1/160)
Aperture: f/2.8
Focal Length: 100 mm

As you can see, the shallow depth of field givea a rather unique perspective when combined with shooting something so small so closely.

This resulted in a few really interesting shots

Exposure: 0.006 sec (1/160)
Aperture: f/2.8
Focal Length: 100 mm
Exposure: -1.65

Exposure: 0.006 sec (1/160)
Aperture: f/2.8
Focal Length: 100 mm
Exposure: 0.00

I’ve got a lot to learn and I also need a lot more practice. Holding steady is crucial in this milieu, even with anti-shake technology. The slightest shift can ruin the shot. Still, I like a good challenge and when things go right the results are quite thrilling.

Sony SAL-70300G – A Modest Review

I don’t claim to be a photography expert. I am self taught through personal experience and what I have been able to glean from various web resources and other photographers. I choose Sony over CaNikon for various reason which I won’t go into in this post. That being said, I am not a reviewer who cares to detail the technical aspects of the equipment I use in a the formal way you see at sites like Photozone where the reviewer gets into detail about distortion, light fall off, vignetting, chromatic aberrations and so forth. I leave that to the experts. Besides, why duplicate what is already there?

What I like to do is share my own personal experience as a fan of the platform and show real world examples in the hopes that others interested in this platform will benefit.

As I have mentioned before, the Sony SAL-70300G lens comes highly recommended from my fellow Sony/Minolta users and is a quality piece of glass.

I was finally able to take my own personal copy for a real test drive. Mounted on the A700 (even without a vertical grip) it is well balanced and it’s easy to use hand-held for reasonable amounts of time.

I had Tuesday off so I went to The Cockrell Butterfly Center. This was Cynthia’s suggestion as a place to try out the new macro lens but I figured I could also take the SAL-70300G along as well to see how it performed.

Exposure: 0.008 sec (1/125)
Aperture: f/5.6
Focal Length: 250mm
On-board flash

I am not a huge fan of shooting with a flash, but as you can see the detail is amazing and the color vivid and true.

Next I wanted to shoot without a flash. Personally, I find the colors and saturation much more appealing in available light and truth be told, I am a high speed elitist when it comes to lenses. I like f/2.8 or faster and the SAL-70300G is only f/4.5-5.6 making it unsuitable for low-light situations.

Exposure: 0.017 sec (1/60)
Aperture: f/5.6
Focal Length: 300mm
No Flash

Fully extended to 300mm at 1/60th of a second. BEAUTIFUL! And thank you Sony for the built in image stabilization or your camera bodies. I jokingly refer to myself as Mr. Shaky McShakerson as I don’t have the steadiest of hands and that can be a real problem shooting hand-held at this focal length in less than optimal light.

Fast focus and SSM makes the the lens practically silent.

I have no buyers remorse at all. This lens does what it is designed to do and it does it extremely well. The 70-300mm focal range is a change for me, personally. But it is proving to be a fantastic and fun addition to my lens arsenal. I anticipate I will use this lens quite a lot in my daytime shooting and am even now working out the packing details in my brain for our upcoming trip.

Additional examples are in my Sony 70-300mm G gallery which I will be adding to as time goes on.
