Shoot RAW

Occasionally I have a conversation with someone about whether you should shoot JPEG or RAW with a DSLR. I almost always shoot RAW. There’s a time and place for JPEG, but I avoid those times and places when I can.

Here’s a great example of what you can get when shooting RAW. I was walking through our kitchen and saw these mourning doves through the window. Well, through two panes of slightly dirty glass, on an angle, uphill. I fired off a few shots, and this was the best one I got.

Before

This photo is sort of terrible. I mean, the shot itself is useable, but we need to coax the awesome out of it, which you can do with a RAW image.

After

Here’s the results after tweaking the sliders in Photoshop. (You can view it larger on Flickr.)

From what appeared to be a terrible shot on the camera screen was transformed into a totally useable shot on the computer screen, through the magic of shooting RAW!

Shooting RAW is like shooting on film, which is why we say we have to “process” the image. Converting the RAW image is akin to developing film. (And yes, there are alternatives to Photoshop for processing RAW images, it’s just the one I tend to use the most.)

Review: GE reveal LED Light Bulb

GE reveal Light Bulb

I received a GE reveal® LED Light Bulb and was asked to write about it. Besides being given the light bulb, I was not compensated in any other way. Also, I’m sort of a lighting nerd. I use lighting at work for photo and video production, and I’m very particular about much of the lighting in my home and office.

If you want to see some of the typical comparisons, check out the GE reveal® Lighting page. The info I’ll provide below is a bit different.

Compact Fluorescent Light Bulb

This is a standard compact florescent light bulb. I sort of hate CFL bulbs. I find the light they produce quite terrible, and the big clunky base of the bulb is annoying. From a design standpoint, I find the spiral ridiculous. I do like the energy saving potential of the CFL bulbs, and we do use some around the house, but overall I hate them.

Standard Light Bulb

This is a standard incandescent bulb. I love these bulbs. They tend to produce a nice quality light, and they are cheap, and the design is beautiful. When I think of a light bulb, this is what I picture. Of course, these are quickly becoming illegal (sort of) and being phased out. Sadly, at some point in the future, you won’t be able to buy incandescent bulbs in the United States anymore. Sadness!

GE reveal LED Light Bulb

This is the GE reveal Bulb, which, design-wise, is close to an incandescent bulb, which is nice, especially if you have shades that go directly on the bulb. (Yes, older lamp shades did have a metal clampy thing that went right on the bulb. I still have some of those lamp shades.) One of the benefits of this bulb is that it matches the physical shape and size of the old incandescent bulbs. That’s a big improvement over the CFL bulbs.

Lighting Difference

As for the quality of light, it’s a pretty nice light. I found it to be just a little cooler than the incandescent bulb… in a good way. I definitely like the light it produces. The LED bulb gives off a great light! Slightly better than the incandescent, and much better than the CFL.

One little annoying thing about the design is that you only get light from half of the bulb. I know this is due to having to shove all the electronics into the other half of the bulb, but I can see this causing issues in some situations where you actually do want light spilling out in every direction.

Old Time Light Bulb

I decided to put the bulb into place in my painting room where I’ve been using an incandescent bulb. Now, our house is old, and the light sockets are old, and this old incandescent bulb has been doing the job fine, probably for years and years, but…

GE reveal LED Light Bulb

When I put in the GE reveal Bulb, it did not work. I tried a few times. I also pushed the bulb up against the fixture, and no luck. It’s worth noting that the socket is a bit wobbly, but the LED bulb just did not work. Maybe there are some sockets it won’t work in?

I should also note that I weighed the three bulbs, because I was curious about the weight. The compact fluorescent bulb (the largest I have in the house) weighed in at 6.4 ounces. The good old incandescent bulb was 0.99 ounces. (Yes, it was less than an ounce!) The GE reveal LED bulb was a whopping 7.3 ounces. That’s a heavy bulb! I can see this causing some issues if you’ve got a lamp that may already be top-heavy. I guess if we’re moving to a world were we have to convert high-voltage AC power to low-voltage DC power in every bulb, that may be the price we pay.

GE reveal LED Light Bulb

I moved the GE Reval bulb to another socket and it worked fine. This light also had a metal shade on it which would normally reflect light down, but since the GE reveal bulb doesn’t really shine light up due to the half-bulb design, the shade probably doesn’t do much. But hey, the bulb worked… that’s good!

GE reveal LED Light Bulb

The good news is, the GE reveal bulb is suitable for damp locations, though it does warn that it is not for use in totally enclosed luminaires. This will limit where you can use this bulb. Even though incandescent bulbs can product a lot of heat, they can also stand a lot of heat, like inside your oven! The electronics used in an LED bulb are sensitive to heat, and may not survive being in an enclosed fixture. (And yeah, never use one in an oven!)

There’s one more feature of the GE reveal bulb I’m really excited about… it’s dimmable! Yes, there are dimmable CFL bulbs, but none of the ones I have are dimmable, and the ones that are seem to be pricey. Incandescent bulbs excel when it comes to dimming. I put the GE reveal bulb in our bathroom fixture and it did indeed dim. It did not go as dim as my incandescent bulbs, but hey, it did work. I then tested it in an X10 controlled lamp, and the results were much better, though there did seem to be a slight flicker at the lowest setting.

GE is marketing this bulb to people who want to have beautiful light in their home (or elsewhere) to “reveal” the decor and surroundings, and for that, I’d say this bulb does the job. It provides a lovely light, and is well designed. A quick search online revealed this bulb to cost about $20, which is ten times what you might pay for an incandescent bulb. Of course the LED bulb should be more energy efficient, and should last much longer. In theory.

So that’s my review of the GE reveal® Light Bulb. Pretty much everything in this review had to do with testing, evaluation, and my own opinion. Now that’s all of that is out of the way, I’ll put the bulb into place and give a real-world test for a while, and then if I have new insights, I’ll share those as well.

Technical and Talented

TnT

Recently I was working with an artist, I mean a real artist. Someone who can work on a giant canvas and create something from nothing. Well, from nothing but ideas, and maybe some imagery. There’s gesso, and pencils, and paint and brushes, and a heck of a lot of time involved, and at the end is this amazing piece of artwork that just makes you happy when you look at it.

Art is pretty amazing when it’s done by talented people…

I was busy shooting photographs and I mentioned to the artist that I really liked her work, and admired the talent and skill it takes to create it. She then said “Well, I wish I was technical” and by this she was referring to my skill set. It weird to hear that, because even though I’ve been using computers for over three decades, I tend to forget the amount of technical knowledge I have. I think there’s a few reasons why.

First, everyone uses a computer nowadays. Well, not everyone, but chances are everyone reading this does. I was using computers at home when most people were using Sony Walkmans because CD players weren’t around yet. Of course the vast majority of people just use computers, but don’t really know how they work, or how to program them, etc.

Second, since everyone uses computers, everyone uses the web. I helped build the World Wide Web. Nowadays every jackass with a Facebook account and a blog is a “Social Media Consultant” or something. Oh, and everyone can build a web site. I wrote all the code for a large corporate web site nearly 20 years ago. That seems weird, but it’s true.

Third, I tend to hang out with people who are like me, meaning, people who know a lot about computers, and who know how to build the web. I like most of these people, they’re awesome, but you tend to forget that you know stuff 90% of the population does know when you hang out with that other 10% of the people who also know the things you know. That’s a strange dilemma.

Maybe I’m just a frustrated artist? I have all these technical skills, and on occasion I can be creative, but I often feel that I’m lacking in artistic focus. It’s all very strange, but I’m finding ways to deal with it.

Which 3D Printer should you buy?

If you were to ask me today “Hey Pete, what 3D Printer should I get?” and you didn’t really provide me any more info on what you want to print, or what your budget is, I’d rattle off a bunch of my own 2 cents, or maybe even 4 cents. So that’s what I did below.

Consider this my opinion as of February 2014. Oh, I should also note that if you really want a ton more info, maybe too much info, check out what my pals at Make did with their Ultimate Guide to 3D Printing 2014 Edition. (Note: You might even see me on page 17.)

Printrbot

Printrbotprintrbot.com
Printrbot grew from a (very) successful Kickstarter campaign, and the original goal was to get more 3D Printers out into the world, and they’ve definitely done that. Their offerings include kits and fully assembled printers, ranging from a few hundred dollars up to about $1,000. The Printrbot machines have been made with laser-cut wood, but they’ve just announced a new printer with a metal frame, which should help improve quality a bit. The default print volume of the Printrbot machines isn’t too big, but if you want cheap, Printrbot is an option.

Deezmaker

Deezmakerdeezmaker.com
Deezmaker also grew from a Kickstarter campaign, and I’ll admit, much of my respect for Deezmaker comes from the super-smart Whosa whatsis and his involvement. If you’ve been around the 3D printing / RepRap community for the last few years, that name may mean something. Did I mention he’s super-smart? I totally trust Diego and Whosa to make high-quality printers and be awesome dudes when they do it. Prices range from $800 to $1,500, a bit more than Printrbot, but I think the price is warranted, as you get a better machine.

LulzBot

LulzBotlulzbot.com
Moving on up, it’s the LulzBot folks! With the new TAZ 3 they’ve created a damn impressive printer. They’ve had impressive printers before as well, and they’ve had a program that included giving hackerspaces free/discounted printers, which is pretty cool. If you’re looking for a bit of a more established company, LulzBot (despite the name) may be a good choice. You’re now in the $2,200 price range though, and they really only have the one model, but from all I’ve heard, it’s a damn nice machine.

So the three companies mentioned so far all have one great thing in common, they’re open source. They’ve all made a commitment to release the files and documentation needed to build your own version of their printers. Without this sort of commitment you would not see 3D Printing being where it is today. The open sharing of knowledge, tools, software, and best practices is what got us here, and that’s important to remember, because…

Oh yeah, there’s also MakerBot!

MakerBot

MakerBotmakerbot.com
MakerBot was the poster child of 3D printing when I first got into it years ago. They did a lot to bring 3D printing to the people, and then they went closed source, and got acquired by Stratasys, a company which holds a lot of patents, and while they do some amazing things in the world of 3D printing, they also threaten to slow the growth of 3D printing through lawsuits, which I’m not a fan of. If your eyes glazed over reading that last bit, a MakerBot may be right for you. To be honest, they make pretty good machines, and you might consider them the “IBM” of 3D Printers. If you need one for work and you want support and a company to call/blame/etc. MakerBot might be right. You’ll probably spend $2,200 or more, though they did just announce a “mini” at $1,400.

So there ya go, my recommendation for buying a 3D Printer as of February 2014. Now, if you want to build a 3D Printer, that’s an entirely different story!

Hand to Hand

Cyborg Beast

About eight months ago I mentioned the Robohand project, and said that 3D printers could change the world for the better, and not just be a way for people to make guns.

The future is now! No, really, it is! It’s February 2014, and through a series of events involving the group E-Nable (also see Google+ and Facebook) I had a small part to play in helping a Milwaukee-area girl get a prosthetic hand.

Nick from E-Nable contacted me because I’m a “3D printing guy” in Milwaukee, and asked for my help. I ended up asking everyone at Milwaukee Makerspace, and while many members jumped in to offer help (either with printing, or donating cash, or both) our pal Frankie Flood at UWM’s Digital Craft Research Lab took the project and ran with it. And yeah, he’s the best guy I know to take a project and run with it. The results have been amazing.

Shea

Shea just got the first version of her new hand. She met with Frankie at his studio to have a mold made of her hand, and to meet with Frankie and his colleague Adream and discuss the process. Frankie then spent a lot of time with other of the E-Nable members trading files, tweaking files, printing a lot of parts, and coming up with new ideas on how to design and assemble a prosthetic hand. It’s been amazing to watch it all unfold. You can get a taste of it by checking the out the prosthetic category on Frankie’s blog.

The next time someone asks you what you can do with a 3D printer, just casually mention that you can change someone’s life for the better.
