Teaching robotics at the AVA Gallery

Uncategorized

Taking some time out of the world of fine art photography to teach some kids a bit of logical problem solving, robotics and programming. Using Lego engineering to solve challenges like getting up a hill, escaping a maze, moving supplies and of course drag racing.

My Lego Mindstorms robotics classes run for four weeks in the summer (always sold out) as well as after school programs in the fall, winter and spring at the AVA Gallery in Lebanon, New Hampshire in the restored Carters factory.

We have a lot of fun to say the least. In the most recent class we built a chase vehicle to carry a camera crew so we could capture first Lego person views of the race.

I used to coach First Lego League team when my son was in middle school in Maine and New Hampshire (4 seasons!). Now I have a bit more laid back approach with the classes and camps.

About Lego Mindstorms: The Lego Mindstorms series of kits contain software and hardware to create customizable, programmable robots. They include an intelligent brick computer that controls the system, a set of modular sensors and motors, and LEGO parts from the Technics line to create the mechanical systems.

Cheap Tool Gets The Job Done – Lens Filter Wrench

Uncategorized

 

Adorama Filter Wrench for 67-77mm Filters, Package of 2

Sometimes having the right tool for the job makes all the difference, especially when the tool costs less than $5. What’s the job? How about a stuck lens filter?

Happens all the time right? Tighten a UV lens filter or polarizing filter on too tight or cross thread it and when you go to take it off, its good and stuck.

Well, there are all kinds of ideas on how to get it off. Here are some of the experts on the FAA forum:

“I always keep a short length (about a foot) of nylon rope in my camera bags. If you loop it around a stuck filter, tightly twist the free ends, then use the twisted part as a handle and rotate, you can easily remove the filter. Never fails!”

..a wide pair of channel locks with a portion of a t-shirt wrapped around the filter with success. Wrap the filter, adjust the channel locks around and snug them closed, gently applying pressure as to not crack the filter. The leverage of the channel locks handle should assist it to unscrew, providing it is not cross threaded so bad.

But before these drastic measures are taken and you put your expensive lens at risk of being scratched or worse – broken, invest some pocket change in some plastic lens wrenches and keep them in your camera bag. They are cheap and do the job without any damage to your lens.

Hint: To avoid cross threading, always turn the filter counter-clockwise when attaching it until you hear or feel the threads engage, then tighten it.

Football fans rejoice! At last you can shower with a giant football!

….

American football (known as football in the United States and gridiron in some other countries) is a sport played by two teams of eleven players on a rectangular field 120 yards long by 53.33 yards wide with goalposts at each end. The offense attempts to advance an oval ball (the football) down the field by running with or passing it. They must advance it at least ten yards in four downs to receive a new set of four downs and continue the drive; if not, they turn over the football to the opposing team. Most points are scored by advancing the ball into the opposing team’s end zone for a touchdown or kicking the ball through the opponent’s goalposts for a field goal. The team with the most points at the end of a game wins.

Auto White Balance Versus Pre-set White Balance

Uncategorized

White balance is one of the first things that confronts and confounds newbie photographers. Part of capturing light is developing the ability to “see” light and all kinds of light from warm tungsten lighting to bright sunlight and setting your camera to properly capture light. 

In the days of color film, one would choose between daylight balanced film and indoor balanced film.  Shoot the wrong film in the wrong light and you’d end up with either a blue cast to the light or a yellowish cast.

One way to “use the wrong film for the situation” was to use filters.  More on filters here.

With modern digital cameras and shooting in RAW mode allows one to easily adjust White Balance in post with programes like Adobe Lightroom. Shooting JPEG on the other hand cooks in the White Balance but it can still be adjusted, just not as easily as in RAW. 

Most of the advice I’ve gotten in the past said that today’s cameras can do a wonderful job figuring out WB so Auto WB is fine. But what happens when you come across a nice warm sunset? Auto WB might read the scene as too warm and cool it down. 

Beyond using “Daylight” for sunsets, Ober Photography suggests using “cloudy” for sunsets to really warm up the scene.

In Adobe Lightroom you can change the white balance for various effects.  But is it better to get it right in camera?  Maybe, because you might over look a dull photograph when your editing your images.

Example moving White Balance off of Auto White Balance

This image was taken in the studio with Flash. Shot with Auto White Balance in RAW and then brought into Adobe Lightroom and then initially changed to the “Flash” setting. The result was too cold for my taste so I applied a Abobe Lightroom OnOne Software Preset called Warming Filter 81a.

Filters in the Digital Age

Uncategorized

Filters 101

In the old days of film photography, photographers often carried around a handful of filters. Because white balance was baked into the film, one would often have to correct for various light sources using filters. The film itself was balance for the yellowy warm indoor lighting or the cool bright white of sunlight. Going from indoors to outside or visa verse required changing film or adding a filter to your lens to cool or warm the light.

Black and white photographers would use colored filters to effect certain color ranges. For example a red filter would be used to make some serious tonal changes: pink and orange go almost white while the deep red displays similar values to the original orange. While the blue and green become very dark.

In the age of digital photography, white balance is not longer a worry and can be changed in post production if you are shooting RAW files. Other filter effects can be achieve using software such as Adobe Lightroom, Photoshop or OnOne Perfect Effects.

A polarizing filter is used to cut glare off windows or water just like a pair of polarized sunglasses. A UV filter doesn’t do anything in the digital age except add a layer of protection to your lens.

A polarizing filter can increase color saturation in landscapes it removes glare off leaves. A circular one allows you to dial in the right effect.

A UV filter can be used all the time. A polarizing filter should not as it takes away one stop or so of light. Also in wide angle shots you can get an uneven effect across the sky.

Just bring out the polarizing filter when you need it to cut glare.

Other Useful Filters for Digital Photography

Here are some other filters you’ll find useful for digital photography:

Graduated filters – If the sky is too bright you can use a graduated filter to darken the sky.

Neutral Density or ND filters – Neutral Density filters darken the scene without changing the light. You can get them in various strengths or get a circular one that can dial in the intensity. Why would you want to darken a scene? The primary reason is to be able to use longer exposures for smoothing out waterfalls to get that silky water look.
