Ladder and Pole (Pladder?) Setup

Ladder and Pole (Pladder?) Setup

In order to get in the right location and the right Point of View, to take the Combat Air Museum panoramic photo, I put together this ladder / pole combination. It consists of a 12 foot stepladder with an 8 / 16 foot 'painter's pole' running up the center and passing through the small hole in the very top of the ladder. The bright orange object just above the fifth step is a Post Level used to make sure the pole is plumb and true.

In this photo, my D700 is mounted at the top of the pole using a Manfrotto 488RC2 ball head...and yes, my camera strap is clipped to the top of the pole as a safety measure..! The pole is extended here to about 15 feet so it extends some three feet above the top platform of the ladder. This allows me to stand on the last 'safe' step of the ladder and still be able to see and frame the shot using "LiveView" to make sure of my composition.

The base of the ladder is large enough to provide a lot of stability and also acts to keep the camera and pole in the correct alignment I use a radio release when I am taking shots with this so that I can maintain my balance and keep my hands away from the camera to eliminate any vibration. I do one button press to activate Live View, double check the image..and then a second press triggers the 7 bracketed shots.

This rig also will allow me to stand about half-way up the ladder and extend the painter's pole up another 10-12 feet while still feeling fairly (!) comfortable about having my gear close to 25 feet above ground..



big electrical pole and a lightpost/stoplight pole.

my scanner is crap so to get decent pictures from my 16mm microfilm escapades (110 reloads, submini/spy cameras) i have to actually use my enlarger. i'm still learning how to work it, but here's the first enlargement from my Minolta-16 P, using Copex microfilm.

the enlarger isn't designed for this small format, and won't go high enough on an 8x10 to fill the frame. also, i had to improvise a 16mm negative carrier by sandwiching the negative between two strips of 35mm film, with a rectangle cut out. works well! what you see is a black border where the mask rectangle is bigger than the image, followed by the rough edge of the rectangle cutout.

print was still wet when i put it on the scanner. this ain't perfect, but it's proof of concept. and i think this is a strong image too!

Technical Pro XTREME1501 Subwoofer, Black

The Xtreme1501 is a Carpeted 15 Inch Powered Subwoofer. This speaker is for anyone looking to beef up their low end and achieve a thunderous low frequency output from their speaker system. The Xtreme1501 has a total peak power of 1500 watts. This is the type of power you need for a large sized venue such as a live stage show, large studio space, showroom or in a nightclub. This subwoofer is an ACTIVE speaker which means you do not need any additional amplifier to power this speaker. The system comes complete with a satellite amplifier that can power two up to two additional loudspeakers. Use this amplifier to power additional satellite speakers orbiting the subwoofer. The inputs are 1/4 Inch and XLR. Connect any standard playback devices or mixer to this connection and send your source through one of the best subwoofers on the market. The passive pass-through outputs of the subwoofer are 1/4 Inch and XLR. Use these pass-through outputs to send the signal to another power subwoofer. Using the outputs of the satellite amplifier you can choose between two speakon and two banana connections. You can use these outputs to power two other satellite speakers. The woofer is 15 Inch with a massive 90ounce magnet and 3 Inch voice coil. This will deliver a clear translation of booming low end frequencies. There are separate volume controls for the subwoofer and the satellite speaker connections. This is key if you need to balance out your levels between the low frequencies coming out of the subwoofer and the mid/high frequencies coming out of the satellite speakers. Also inside you will find a switchable high pass filter for the satellite connections. If you are sending your whole signal into the subwoofer use the high pass filter.this will send the low frequencies to the booming subwoofer and the high frequencies will pass through to the mid/high satellite speakers. This is a professional set up meant to properly send your frequencies to the proper speakers.
