Introducing JoJo

I was recently spoiled this Black Friday! 🙂 I had been needing a new laptop for a LOOOONG time as my little old white Macbook was likened to an old flee bitten dog with 3 broken legs trying to limp itself back home so it could be shot out of compassion. The battery died and ceased to work at all, the screen was wrecked, I’d gone through 3 hard drives, but it’s still kick’n, even if it is only with one leg. 😉 Long story short was, this past Black Friday I took advantage of Apple’s “generous” $101.00 off deal. I’d been eying up a new Macbook Pro, but didn’t want to spend the long dollar for the Retina display. I need a laptop primarily for work – running presentations and bible studies, movies for the confirmation kids, etc. Nothing really over the top powerful. But I also thought it would be cool to have a mobile computer for photography needs as well. But the more I priced things out the more I concluded that if I’m gonna be slugging through D800 RAW files (price drop coming this December!), I’d need massive grunt power. Like I mentioned, I didn’t want to spend oodles of cash. So, I decided to dump the photography needs from the equation and focus on a simple, light and portable solution for work. And, I made up my mind on a Macbook Air.

I had looked at them awhile ago and concluded they were for trendy vegan hipsters whose  limp wrists couldn’t hoist the heft of a Macbook Pro at Starbucks whilst sipping a mocha frappa latte chino. 😎 I had concluded that the MBP was the only way to go. I liked the idea of the SSD over the traditional hdd and if I had got the MBP, the first thing I was going to order was a SSD to use in it. But it was an extra expense. Plus, the 13″ version that I was interested in maxed the RAM at 8GB. If I couldn’t have 16, I wasn’t interested. So, I decided to give the Air another look.

I chose the 11″ model because of the footprint. It’s barely bigger than an iPad!!! (The original one, not that new miniature freak show). And it is thin. Like razor thin!

But what absolutely blew me away was how fast it is. My main computer is a 21.5 iMac with the Core Duo 2 chip and 16GB of Ram, not a slouch but not  the latest kid to the party either. I wanted to test this little Air’s performance and I know of no better way than to try to choke it to death on D800 RAW files. I had an 18GB library of some files I shot with my friends camera. So after I got Aperture 3 installed on the Air, I attached my USB 3.0 Seagate drive and got ready to give the digital Heimlich  maneuver. But I never got the chance. I watched as the RAW files loaded up in the library and snapped into focus. There was hardly any long delay waiting for the files to render. I slid the mouse around the file look at 1:1 view and the little computer kept up with no issues. In short, it’s FREAKIN’ AWESOME!!!! 😀 With the 1.7 i5 chip and 8GB of RAM, this sweet little computer cooks RAW for breakfast. I was astounded at the performance. But the achilles heel of the 128GB SSD drive is the rather conservative size. Not a whole metric tonne of room for storage. However, with the sweetness of USB 3 and Thunderbolt, you’ve got awesome high speed mass storage solutions. I plugged in my USB 3 Seagate 1TB drive and it ran the Aperture library without a hitch. And, the drives are only $100 buckeroos. Cheap.

So to recap, I’m really happy with the Macbook Air! It was rather serendipitous that it turned out to be an exceedingly capable photography computer as well as basic “light-duty” portable laptop. Ideally, a larger 15″ retina screen would be nice for doing tethered shooting, but the 11″ is just that much more portable. Easily fits in a camera bag with no issues. It’s incredible value for the money I’d say. It was basically $1100 in the configuration I bought. We know that these little computers aren’t going to be upgraded ever, so I bought the max RAM I could. I’m confident that it will serve me for many years to come, just like my old palliative Macbook did. 🙂

Oh and as for “JoJo”? I asked Phoebe what I should name the new computer. “JoJo” was the answer. 😉


HDR Tutorial

This is a brief tutorial on making HDR images. There’s zillions of other posts/pages on the information super highway already so you can look up more info there about it. But this is how I do it. Which makes it infinitely better. 8) Just kidding! 😉

HDR stands for High Dynamic Range. It’s been around forever conceptually, even since film days. But now, with digital it’s easy and fun. Get a camera and a tripod and find a scene that has loads of contrast: lots of lights and darks. The idea behind this kind of photography is to keep all the detail in the darks and in the light parts of the image. Because the camera currently cannot capture the same amount of dynamic range that the human eye can see, in one camera photo you don’t get as much range as you see with your eye. So, you take 3-7 photos of varied exposure and layer them together with software. I use Nik’s HDR eFex Pro. It’s super slick and comes with many final image presets you can apply to stylize the final image, making it look as surreal or as realistic as you want.

OK, here’s a sunset one I took the other night. And in all truth, it’s not how I typically do it. I was on top of my roof with my 70-300 lens and I did this handheld, which isn’t optimal. Get a tripod so there is no camera movement.

So, the first image: bang. Here it is.The camera meters the scene and determines that this is the best balance of light and dark. We get all that rich colour in the sky & the river. But the valley hills have gone dark and silhouetted the evergreen. This was at ISO 400 f/8 70mm and the shutter was 1/100.

 The next shot speeds the shutter up to 1/200, recording an even darker, more saturated image. This one gives the mad colour, but kills off almost all the detail in the hills.The third image washes out the sky but it lifts the details up out of the hills with a slower shutter speed of 1/50. All three images are 1 stop of light apart from each other.
Now, technically, it would be better to get a couple more images here to further lift the details out of the dark regions. But, as I mentioned, this was handheld. If you have a tripod it’s easy to do.

Then, after feeding the photos into the Nik software (I use it as a plug in with Aperture) you can arrive at the final HDR image. There’s loads of darks and lights, rich colours and highlight detail that otherwise would have been lost. HDR is having your cake and eating it too. 8) When you stylize the image, you can make it look wild with texture, like I did here to make the clouds go boom. But you can also finish them to look realistic too which I did for this photo of Good Shepherd Lutheran Church in Regina. The light pouring in from that window would have made getting a balanced exposure difficult.

So there you go, a quick tutorial on HDR. Always use your histogram to see if you’ve clipped any highlights or darks in the image. 8)
