HDR Photos [Photoshop and Luminance HDR]

HDR Photos

It’s been a while since I posted anything about HDR imaging, and I realized that I never put Adobe Photoshop CS5 to the test. I did try creating an HDR image with CS4, but was disappointed with the results…

In the image above you can see my final output of an image. On the left side is all Photoshop, and on the right side is Luminance HDR (formerly “Qtpfsgui” for you old timers.)

Now for both of these images I did the HDR+ thing I talked about a while back, where I blend an HDR image with a normal exposure. Personally, I like the way those turn out, so it’s pretty much how I do HDR.

Here’s the image from Luminance HDR. (View it large at Flickr.)

I think the Photoshop image looks better in the sky… it looks a bit cleaner, while the Luminance HDR image has a little bit of banding going on. You can also see some differences in the trees, and the water, but I think the rocks in the foreground really show the difference, and I prefer what Luminance HDR did.

This is only my first attempt at comparing the two applications, so it’s not entirely scientific. I did go into each file and tweak it a bit to try to match them closely as far as the color balance, but the detail is where the difference is most apparent. I also didn’t see any way to adjust the tonemapping in Photoshop, while Luminance HDR has a ton of sliders and options to twiddle with.

I suppose next time I could combine the two final images into a ‘final final’ image that would be some sort of SUPER HDR+ image. (I’ll add that to the ‘to do’ list.)

Crackerjack on Kickstarter

Crackerjack

Over on Kickstarter is a project called Crackerjack, which happens to be a comedy that will (possibly) be shot here in southern Wisconsin.

I should have mentioned it a few weeks back, because now there are only 19 days left to fund it.

They’ve raised only a small portion of their goal, and if they don’t reach it, the fallback is to fund the film on credit cards and go into debt, which is pretty common with low-budget films…

The most interesting thing to me has been the approach they’ve taken in their campaign, as well as the management of it. I’ve looked at a lot of Kickstarter campaigns in the last year. Some I’ve funded, and many I haven’t. It’s interesting to see which succeed and which fail, and try to come up with a formula that will work… if such a thing exists.

(Disclaimer: While I do know one person involved in this project, I had nothing to do with this campaign. I was told that they may want me to do some “technical consulting” though, which will probably just involve talking about the RED DIT workflow.)

Analog Photography!?

Skylark

It’s been a while since I thought about my film days, and honestly, I don’t know the last time I’ve use the term “digital photography” when describing “photograpy” but there are still people who shoot film, RachelK is one of them, and another is Troy Freund.

Troy wanted to let me know that he’s involved with an Analog Photo Seminar at Cardinal Stritch University on October 9, 2011. Here’s the details:

This seminar will feature presentations and demos by Wisconsin film-based fine-art photographers. Nick Olson, Dr. Yong-ran Zhu and Mark Brautigam will present on their experiences in large-format photography. Over the lunch-break, I will talk about the experience of working with Leica rangefinder cameras.

Each photographer will give a 30-40 minute presentation of their work, followed by a short Q&A session. The afternoon will be spent with each photographer giving a hands-on demonstration of their working methods.

See Troy’s blog post for all the details.

If you’ve got any questions, I’m sure you can hit up @midwestphoto on Twitter and he’d be happy to answer them…

Virgin Mobile MiFi

MiFi

About 6 month ago I picked up a Virgin Mobile MiFi 2200 Intelligent Mobile Hotspot. I just call it a MiFi, as do most people. It’s basically a 3G modem which lets you connect up to 5 devices (via wifi) and get them online.

The decision to get the MiFi was driven by the service of Time Warner Cable… after a two-day outage that is. The work I do requires an Internet connection, and I thought the MiFi would be a good backup for Time Warner failures, as well as the occasional traveling I do.

Now, there’s plenty of reviews of this model, in fact, here’s one, and here’s another. You can also find review on Amazon and elsewhere, but hey, this is my personal experience, rather than a straight-up review.

I liked the idea of a prepaid account because I just wanted to buy the device and the “pay as you go” model fit my usage. Of course you can’t predict the future, and those Virgin Mobile folks have changed the pricing more than once. When I was planning to buy one, the 3 options were $10, $20, and $40, and by the time I bought one weeks later, it was $20, $40, and $50. And who know? They may change again…. Urgh.

Anyway, since I’m an AT&T iPhone customer with only occasional needs for tethering, this is still a better (cheaper!) option for me at this point in time.

So here’s my review (which isn’t a review.)

When I first tried using the MiFi at my house, it seemed to work fine. I was satisfied that it would be a good backup solution to another Time Warner outage. My next use was at the Milwaukee Makerspace where I used it as backup for the sometimes unreliable wifi there. It seemed to work OK, though a little slow. I wasn’t sure if it was the building, or the location, or what. I was less than impressed this time. Next was a grade school near West Allis, and the results were similar to at the Makerspace, a bit slow, but better than nothing. I’d also seen then device get really hot a few times. I’m not sure what causes this, as sometimes it happens, but it’s not consistent. I should note that on all of these occasions, it was my MacBook that was connected to it.

The thing is, I’ve seen crappy 3G connections on my AT&T iPhone around Milwaukee as well, so I don’t know if it’s saturation of the network, or the buildings, or what.

My next big test was on a drive from Milwaukee to Minneapolis. This time I used the iPad instead of the MacBook, and I really didn’t notice any connection problems. I don’t know if any of it had to do with how iOS works, but using Reeder, Oosfora, and Mobile Safari was pretty smooth. Sadly, Maps did not work the way it does on an iPhone, or how I assume it works with a 3G iPad. It just showed my location back in Pewaukee. (Oh, my daughter actually used her iPod with the MiFi as well, though I think she just spent a few minutes Facebooking.)

We stayed in Minneapolis at a hotel that did not have free wifi. (Yes, sadly, they still exist.) The MiFi was a champ here, providing us with our own Internet connection. Again, we just used the iPad and I didn’t notice any connection problems.

Now, on to the east coast… where I wish I could say the experience was just as good. I didn’t need to use the MiFi until I got to Preston, Maryland, and the house we stayed at had no Internet connection. Being able to connect was totally hit-and-miss. Sometimes it worked, and sometimes it didn’t. Placing the MiFi up against a window seemed to help. I formulated in my head getting a rubber suction cup so sticking it onto a window were possible. On the last day we were there, the MiFi would not connect at all. It was raining pretty badly, so I wasn’t sure if that was the cause, but then realized that it kept showing the device as “Not Activated” and for some reason, I had to go through the whole activation process again. Luckily Mobile Safari (yes, still using the iPad) managed to maintain the needed activation codes so I didn’t need to type in anything. Still, this “reactivation” was a pain to deal with, and I hope I don’t need to do it again. After the reactivation, all was well again. I even ended up using it on the plane at BWI while we sat on the runway for 30 minutes.

In the end, when the MiFi works, it works well, though occasionally a bit slow. The ability to connect seems to depend on a number of factors, and I just need to live with the fact that there is no guarantee it will work at all. I suppose that’s better than nothing… right?

I’d love to hear others’ experiences using this MiFi device, or any others.
