Digital Photography 101: What’s an SLR Anyways?

This is the first part of a multi-part series of articles I’m writing about digital photography, as I learn more about it. You can find links to the other articles at the bottom of this one.

So, you just got a new Digital SLR for your birthday, or mabye you’ll get one for Christmas, if you’ve been a good little boy or girl this year…

Or maybe, you’re just lusting after the latest Canon EOS Rebel XT, or you’re eyeing a used D60 on eBay. Either way, you find yourself asking the question:

What the hell is an “SLR” anyways?

I did, as I started to contemplate writing a “Digital Photography 101″ series for this website. (I’m starting this little series of posts with this one, because I just graduated to using a real 35mm Digital SLR that I bought off a buddy that had out-grown his. As I learn stuff, I’ll try to pass it on, and hopefully people will correct any inaccuracies I come across, so I can learn faster myself).

So, I turned to Google, and the best answer I could find to this question came from the best information source on the ‘net… the Wikipedia:

Single-lens reflex camera

The single-lens reflex (SLR) is a type of camera that uses a movable mirror placed between the lens and the film to project the image seen through the lens to a matte focusing screen. Most SLRs use a pentaprism to observe the image via an eyepiece, but there are also other finder arrangements, such as the waist-level finder or porro prisms.

The shutter in almost all contemporary SLRs sits just in front of the focal plane. If it does not, some other mechanism is required to ensure that no light reaches the film between exposures…

So, if you were wondering, go read the full entry for SLR on the Wikipedia, and sound smarter next time “SLR” comes up at a dinner party.

Expect more as I learn it.

Ars on Aperture

Ars Technica on Aperture 1.0 – this is the review I’ve been looking for. If you’re interested in Aperture, read this review.

update: After reading the review completely myself, I’m left thinking that maybe Aperture isn’t what I need, and maybe it is something I’ll want, evenutally. I don’t know, and haven’t made up my mind…

The Ars conclusion:

Maybe by 2.0 Apple will have the foundation sorted out. At this stage Aperture is a big, expensive misfire and considering the hefty price tag, I can’t think of a reason to recommend it. Reading this review, you may think I sound jaded, but I am genuinely angry for those who shelled out US$500 for a program that promised professional results and failed to deliver. Thanks for coming out Aperture, now get off the stage.

60 hours and a pre-wedding iMovie

A few friends of mine and I ‘volunteered’ to put together a movie for a couple of friends of ours that are getting married this weekend. I got roped in because I’m the one that owns a Macintosh, which means I have iMovie and iDVD

The goal: a 10-20 minute video that gives the couple’s friends the opportunity to share something about the couple with the audience, show a bunch of photos from the couple’s history, with a little music running in the background.

So, we set out a month of more ago with the camera, and my two friends started video taping. They shot around 3 hours of footage. This was a bad start… I knew it, but figured we’d be able to work with it.

One thing I’ve learned about making movies over the past 10-12 months (that’s how long I’ve been making movies using the Macs in the house) is that shorter is always better. If you can make a movie short and sweet, everyone loves it. If it’s long, it always seems to drag on, because the subject gets a little old. It happens…

This past Sunday, we started editing down the 3 hours of footage.

The first few “interviews” were horrible… the interviewees just rambled and rambled, and they didn’t speak up enough to make it easy to hear them. This is partially due to the fact that the two folks that worked the camera for us had never edited a video, and thus they didn’t know that the subject in the frame needed to speak up, and for editing ease, needed to give us good, sharp soundbites. The last few interviews were much better… concise and to the point. I also noticed that the first few interviews were all women. The last few were men. I’ll let you make the connection between rambling vs. not rambling and the sexes.

By Monday, we had it edited down to 45 minutes worth of sound bites/video snippets… Then I used iMovies “Extract Audio” feature on all of the video clips at once. Bad idea!

iMovie on a 2GHz iMac doesn’t like converting all of that audio at once, and it shit on us after the conversion process… so we lost all the work we’d done on the editing side up to that point.

Luckily, I’d created a backup on the original movie data. On Tuesday, we edited again, and were much better at it, because we knew what we were looking for in that 3 hours of footage. It still took a little while to edit though… about 2.5 hours this time. Then we got the footage in order, and called it a night.

On Wednesday, we decided to start putting the pictures with the video clips and to just make it work. After 4 hours of work, we had a finished product that was 20 minutes long, and looked pretty good.

Thursday night, we added the music and some final title screens and transitions… then I adjusted the volume levels of some of the quieter video segments and the music… and I made a DVD using iDVD, and burned a copy.

I watched it at 10:00 p.m. or so, and those low level video segments were still too quiet to be heard on the TV after I made a DVD out of the video… so I re-edited the movie to get rid of the background music completely, and brought the levels way up for the quiet video segments. I called it a night around 11:30 p.m.

The video is done. I personally spent around 18-20 hours working on this thing. My two friends that shot the video and helped edit it spent at least that long as well. 60 man hours, a lot of money on gas, and a few more grey hairs… that’s the cost of this movie. Finally done.

We should have charged for this work.

Lessons:

  1. iMovie is a great tool, it handled 3 hours of video footage editing just fine… It was a bit underpowered for the things we wanted to do with this video, but it did the job we needed it to do just fine. I should have done this in Final Cut Pro, but I wasn’t going to spend the money on it yet.
  2. iDVD rocks! iDVD will put a very professional look on your DVD and is worth paying for all on its own.
  3. Editing 3 hours of video footage down to 20 minutes worth of good stuff ain’t fun. Next time, spend a lot more time getting the people in the movie to be better video subjects.
  4. Better Together by Jack Johnson on In Beetween Dreams is a great song for a wedding.
  5. If you ask your friends to make a movie for you, make sure you know what you’re asking for… it’s a lot more work than anyone that hasn’t made a movie before might think… and you get what you pay for.
  6. The quality of your movie really comes down to the quality of the source material you have to work with. If you have crappy source material, no amount of technology can make it better. If you’re shooting the footage yourself and can direct the actors, focus them on sound-bites and make them speak up if they aren’t right in front of the camera.
  7. I might have to invest in a microphone and light setup for the DV camera.

Overall the process was a great learning experience, and we’ve created a great movie… I’d put it online for you all to watch, but I’m not that proud of it and don’t want to pay the hosting/bandwidth bill for a 20 minute movie. If you want to watch it, contact me and I’ll tell you where to send that $5 check to cover burning it and shipping the DVD.

Buying Rechargeable Batteries

I needed to buy some rechargeable batteries today. I thought about stopping into a store to buy them, but then I realized, I didn’t really know where to buy them. Radio Shack? Best Buy? CompUSA? Circuit City? Fry’s?

So, I came home from lunch and started with Amazon.com, mainly because I have an unused gift certificate there. Amazon’s great for some things, but finding products that you aren’t sure of how to search for, it’s not. Search for “rechargeable batteries” and you mainly get results for camera batteries, with a few normal sizes like “AA” or “C” but try as I could, I couldn’t find the chargers for “D” cell batteries, which is what I really need (the 3 month old’s toys go through batteries like a seive).

I turned to Google next, and viola. I found BatterySpace.com. Not only did BatterySpace.com have all of the batteries I might ever want to buy, but their Battery Knowledge page tells me what I need to know about the batteries I’m buying. They also have a couple of decent charging options.

So, I just ordered a new charger, with a multi-pack of different batteries, and 8 extra “D” cell batteries.

I like their site, and will let you know if the batteries are worth anything after I receive shipment.

(This post is posted for the benefit of other new parents, or soon-to-be parents looking for rechargeable batteries).

New Kid equals New Camera

So, the kid is two weeks old as of yesterday. The day after we brought the kid home, I headed up to Fry’s for the after Thanksgiving sales.

I was in the market for a new digital camera. You see, the one we had was an old PowerShot S100 DIGITAL ELPH that we bought back when I worked for MacNN, in 2000. It’s a four year old digital camera and it’s definitely seen it’s better days.

I didn’t research this replacement purchase, as I knew from using the S100, that I wanted a Canon again, and that I really wanted an Elph again. So, I figured I’d get the top of the line Elph that was available when I walked in the door.

I needed the camera that day, because the old S100 just wasn’t giving me good enough photos, and I had a new kid to photograph. I wasn’t going to let myself kick myself for crappy photos in 20 years of my first child.

So, at Fry’s last Friday, I decided on buying the S500 for a few reasons:

1. All of my accessories for my S100 work on/in the S500. Same battery (I have two), same CF cards (I have 4 512MB cards), same form factor = same carrying case.
2. It’s Canon Elph, and I’ve never seen anything but good reviews of them (S100S500).
3. I already know the basics of the Elph controls and platform… point and shoot baby!
4. My best friend just bought S400 and really likes it.
5. It was on sale for $360. (I paid $500 for the first S100 I bought 5 years ago.)

I’m really pleased with the purchase so far, and have taken at least 50 pictures a day for the past two weeks (some of them are posted here).

Compare the older S100 photos with the newer S500 photos like:

This closeup of a friends’s kid [S100], versus this close up of my kid [S500].

Compare the way these two photos were shot in automatic mode:

S100 image of my dog, versus this S500 image of the dog and the kid. Notice the better range of colors from the S500 and overall better image?

I took these shots with the new S500 without a flash and using the automatic features of the camera: Tree ornaments and the kid with the tree and a friend. I would have never attempted those shots with the S100, because my experience with shots like this one didn’t turn out the way I’d have liked them to.

At the end of the day, I’m an amateur photographer, and always will be, but I want to take good shots when I do take them, and I think the S500 will help me do that. It’s definitely a leg up on the S100, and it was a good investment. My initial success with some of those photos has encouraged me to read the manual a little more, as well as learn more about shutter speeds, film speeds, and the like, so I can move into using the camera in manual mode… to take better shots hopefully.

I’d recommend this model to anyone else looking for a compact, portable, and more than capable digital camera. I’ve really come to trust Canon with their digital cameras. This is the second digital camera I’ve bought from them, and I also own a Canon DV camera.

Fischer FVD-C1 CameraCorder and the Apple Store

The wife and I visited the Grand Opening of the Barton Creek Apple Store today, and while there, we spotted a Fischer FVD-C1 CameraCorder. The CameraCorder is an amazing little piece of engineering and swayed me with it’s tiny form-factor and great specs.

The machine is small (very small). It’s less than 3 inches front to back, 4.3 inches tall and 1.3 inches wide. It weighs about 6 ounces (about a third of a pound)

The specs from the sales website look like this:

  • DVD-Like quality video resolution (VGA:640 x 480; Full-motion 30 frames per second)
  • True 3.2 Megapixel digital still images
  • 3.2-Megapixel CCD
  • CD-Quality stereo sound (AAC Audio)
  • Up to 30 minutes of DVD-Like quality recording or 80 minutes of VHS-quality recording (with supplied 512 MB memory card)
  • Up to 491 pictures in high 3.2 megapixel resolution (2048 x 1536) mode or up to 3931 pictures in normal 0.3 megapixel resolution (640 x 480) mode (with supplied 512 MB memory card)
  • 5.8 X Optical zoom lens; 10 X Digital zoom
  • Lithium-ion battery and AC operation
  • Thin Film Transistor (TFT) LCD, with 110,000 pixels of resolution

The specs and manual say that the battery should last an hour under normal video shooting conditions, and the 512MB SD card that came with the CameraCorder should shoot anywhere from 30 minutes to 1 hour and 20 minutes of video, depending on the quality setting being used (actually, it says it can shoot a lot more than that, but I don’t anticipate shooting at the worst quality setting available ever). It also supports USB 2.0 transfer of data, so it shouldn’t be too slow to use (I was afraid it might be USB 1.1 or slower at the store). So, I’ll play with the CameraCorder this weekend and see what I really think about it.

The Apple Store will take a return for a 10% restocking fee, so even if I only use the thing for a week and take it back, I figure it’s a great price to test it out for a full week.

If I like it alot, I’ll turn to Amazon.com to buy a bunch of 512MB SD Cards for ∼$75 each, and I’ll start looking for an extra battery for backup use.

Here’s what’s funny about the whole purchasing process. While at the Apple Store, I was able to go to Fisher’s website, Apple’s website, Amazon.com (and any other shopping site I wanted to) to research the product and the price at different retailers for the CameraCorder and the SD cards that it uses. I found the CameraCorder at Amazon.com for $40 less than Apple was selling it (and $140 less than Fisher was selling it directly). The 512MB SD Cards for $75 at Amazon, while the Apple Store was selling 256MB SD Cards for $99, so I waited on buying that at the Apple Store, while buying the CameraCorder for a slight premium, because it’s easier to return something to Apple than it is to Amazon.

It’s interesting to me that Apple allowed me to price-shop and compare other retailers while at their store, knowing that I’d still choose to buy things there if the benefits of doing so were worth it to me. Granted they lost a SD card sale, but they didn’t even have the 512MB card I wanted, so they’d already lost that sale.

Anyways, the new CameraCorder is charging now, and we’ll test it out this weekend to see how we like it.

Here’s a review from ZDNet.

Buying a Digital Video Camera

I’m researching digital video cameras. I’m in the market for one for the wife and I, and I’m finding that figuring out which one to buy is tough. The big publisher’s guides to camcorders are useless to me, either not providing enough information, or not providing enough facts on which they base their recommendations.

There is almost no documentation at the big box retailers that carry digital video cameras, and the sales people are only moderately helpful.

Thankfully, Jeff Keller’s DVSpot.com is available. It has a fantastic glossary of DV Terms, which, for someone just starting to look for a video camera (my first ever) is invaluable. (Jeff owned iMac2Day.com before MacNN bought it. I ran the site back in 1998/99).

I own a Canon Powershot S100 digital camera, and I love it. It was the first generation Digital Elph, and has been a constant companion for 4+ years. It works well and is still a great camera (though we’ve gotten sand and other stuff into some of the gears over the years). I’d like to buy a camcorder with the same sort of quality.

Without knowing anything about the manufacturers, I’m partial to Canon and Sony (just because of their brand equity in my head), though Hitachi, Panasonic, JVC and Sharp make DV camcorders too.

I think I want a camera that supports Analog to Digital conversion, though that’s not mandatory, and more of a nicety… I’ve got a few old VCR tapes I’d like to convert to digital format.

After spending a few hours reading the reviews over at DVSpot, these cameras are on my list of contenders:

Canon is offering quite a few promotions on their cameras through June 30th from their CanonDV website.

All in all, I’m leaning more and more heavily towards buying a Canon. Now which one?

I’ll keep shopping around, and will gladly take any suggestions that my readers might have. June 30th is my current date of purchase.

Oh, and why am I shopping for a DV camcorder, you might ask? The wife is 11 weeks pregnant (due in November) so I want to get one now, so I know how to use it when we need it.

iMovie notes

On the plane back to Dallas, I figured I’d play with creating an iMovie of our photos, since Steve Jobs showed such a cool demo of his kids at the last MacWorld Expo Keynote I went to. It was a good two years ago, but the demo was cool, and I still haven’t played with iMovie ever…

I found iMovie to be pretty intuitive after playing around with it for 20 or 30 minutes, but it was really quite slow at rendering photos into movie clips, unless I only took 5 or 6 photos at a time and tried to render them…

The first thing I tried to do was drag 152 photos into the movie track area, only to find iMovie barfing after image number 75 or so… It just didn’t want to take that many images at one time…

I quit iMovie and started over… this time, I tried dragging one or two images into the Movie tray, and viola, it worked just fine, but it still took a good 5-10 seconds to render the clips.

I played with transitions and titles on 5 or 6 images, and then made the mistake of trying to drag 50 or so images into the Movie tray… bad idea…

iMovie didn’t like doing that with any real speed…

So I hit <CMD + Z> (the key command for ‘undo’) and interestingly enough, iMovie quit working to render the 50 image clips, and put them in it’s ‘trash bucket’. Those 50 or so images accounted for 589MB of trash… geez… that’s a lot of scratch disk space…

Then I played with the “Ken Burns Effect” settings, so that when I dragged an image into the Movie Tray, I wasn’t having to render an effect, rather, I was just showing the photos for 3-5 seconds, and there was no zoom involved… this made iMovie play a lot nicer… it didn’t try to ‘render’ anything anymore, and was much faster at importing photos…

But, after playing with iMovie, and exporting a 45 second movie that weighed in at 401 MB and looked like crap (in quality) compared to the iPhoto slideshow I’d built, I was ready to throw in the towel…

Maybe when I have kids and a DV video camera, I’ll then take some time to play with iMovie a little more and actually learn how to use it… until then, it’s one iApp that I just don’t need for the time being…

Free software’s only worth what you would pay for it, and in this case, I’m glad it’s free.
