Compact Gazebos are highly portable and strong. These poptents provides instant shelters, easy up tent, fold down and small enough to fit into the boot of a small car or any vehicle where space is limited.
So I wrote a program that could read the red, green, and blue values making up each pixel in an image. Now by reading a line of an image, I could get the spectrum my sensor sees with the red, green, and blue pixels. But there's some noise so ideally we'd like to use multiple lines so hot pixels and dead pixels aren't a problem.
I made it adjust each line so the values are about the same. That way it's still weighting the dimmer parts of the image significantly.
The other problem is the lines might not be exactly vertical -- I was just hand-holding the camera. If the lines were slightly tilted, it'd blur out small peaks and whatnot. So I wrote something that would figure out if it should shift the line relative to the line above/below it -- Indeed, it found my picture was skewed somewhat, but the offsets make a nice line, so I think it's working.
This is the result. The peaks on the graph correspond to to the spectrum I found on wikipedia, so I picked the four major peaks and their wavelengths in nanometers, and I plotted them against the column number in my picture, and found they made an almost perfect line (R squared of .9999). So now I can interpolate and extrapolate the wavelengths of every column in my image. Now I have a real X axis :-)
A few things I noticed
The red line drops down to zero in the blue and green peaks. I double checked the original image and it was the same. I don't know what the deal is with that. I don't think the other spectrums i took pictures of did that. . .
The blue pixels seem to have a very extreme filter from 530-580nm.
Green crosses above blue at a certain wavelength. In theory, that wavelength should be the same regardless of the light source. Ditto for red crossing above green.
Practical compact washing machine (50x50x70)
Working good, only need to replace the water extraction tube (easly found in any supermarket)
Before: 100 CHF (negotiable)
now: 80 CHF
This compact cassette once ruled the world and later lost its regime to the modern counterparts....
Thanks to PHILIPS ... to enhance the flow of music with this tape...in 80s and 90s...

Experimenting with my D90 and Mamiya lens for a tilt shift effect. I like the Sutter St Garage, so hung out there and shot some photos.
Nikon D90
lovely, nice to keep in the hand, bright/fast lens for low light, compact for any pocket ...
LCD display do not have lighting :(
The 3.6V Rechargeable CR123 not work with my camera :(
Battery cover is separate from the body :(
Appia Compact can perfectly convey high performances in little spaces; it is a traditional machine conceived for those places that want to offer their customers excellent coffees and cappuccinos, but that have a reduced operative space. In only 55 centimetres width, Appia Compact enables to work in complete safety, it is user friendly and guarantees a superior quality in the cup.
Suitable for:
locations with minimal counter space, restaurats, small coffee shops and coffee carts.
Olympus made some really good compacts over the years.
All these are nice to use and produce great images.
The XA4 is one of a few fixed lens cameras that is wide angle.
A fine lens and it focus down to 0.3 metre.
Things I don't like are no filter / lens hood mounting, and DX coding. The DX is easily over ridden with a bit of electrical tape then I can set the ISO manually for a bit more control.
The 35RC needed new light seals and I have made these from black felt rather than foam. Only other issue with this is the battery. Best solution is a thirty quid batery adapter from the Small Battery Company. Otherwise it is off setting the ISO to compensate from slightly higher voltage of the S625PX silver oxide batteries that is available now.
The Pen has limited versatility but it works really well in most conditions except low light, it just stops working when it gets to 1/40 at f2.8. So fast film in the winter.

These are the last of the CD and water drop photos I took a couple weeks ago. I have been busy editing some of my Smoky Mountain and Zoo shots lately and forgot about these. Enjoy!!!!
