Transferring 35mm Slides to Your PC. Transferring 35mm Slides to Your Computer Quickly and EasilyApril 2006 Anyone beyond a certain age or who has inherited photos from their parents will have a quantity of 35mm slides they want to get into their PC. I don't know what the appeal was for 35mm slides back then, maybe it was dropping them all into a Kodak Carousel projector and just storing the loaded cartridges for ready use, but whatever the reason my dad left me 100's of slides.

I have worked out a simple technique for getting adequate quality digital images of 35 mm slides using a typical digital camera and a cheap camera store accessory. But first let me tell you about the dead ends I investigated before finding my own solution. Background There are several ways to get slides into your home computer. Options 1 and 2 are prohibitively expensive for me, especially since the low-end slide scanners don't get very good reviews. Flatbed Scanner Since I spent so much time trying this approach it seems worth a passing mention. Scoopt | Home. Schlieren photography.

Schlieren photography is a visual process that is used to photograph the flow of fluids of varying density.

Invented by the German physicist August Toepler in 1864 to study supersonic motion, it is widely used in aeronautical engineering to photograph the flow of air around objects. Optical system[edit] The basic optical schlieren system uses light from a single collimated source shining on, or from behind, a target object.

In schlieren photography, the collimated light is focused with a lens, and a knife-edge is placed at the focal point, positioned to block about half the light.

AutoStitch works from unordered collections of images, automatically finding matches between images using the SIFT algorithm.

It then robustly aligns all images and uses advanced blending algorithms to form seamless panoramas (see below).

Stitching programs vary wildly in their usability and quality of finished image. I prefer the one Canon gives away for free with every digital camera, even their cheapest. Most other software is impossible to figure out, while others slop together images without predistorting or mating them properly. Software that gets these two things right solves 90% of the problem. You can't simply "stitch" together images.

The software needs to know how much angle the shots include so it can do this distortion correctly. Unfortunately many panoramic utilities simply stitch together images without predistorting (bending) them first. The Final 10% AutoStitch. NEWSROOM :: oemagazine, OE Reports archives.

Author: J.A.J Aaronson - Updated: 5 October 2010| Comment One of the conundrums that has faced photographers since the very inception of the medium has been attempting to work out how to effectively capture movement. The representation of motion in a still image has been a problem with which many photographers have grappled and with which almost as many have come up with entirely different solutions. The potential ways in which you could go about capturing motion are manifold; one need only look at a selection of well-known photographs for evidence of this. The way in which you represent movement is likely to be determined by the nature of your subject.

Long Exposure The capturing of motion depends in great part on effective use of shutter speed and aperture. Sharp Images It is not always necessary, however, to show the progress of movement in order to make it clear to the viewer that movement is occurring. You might also like...

How to Make a Large Flash Diffuser. Making nice photographs when all you have for lighting is a bunch of tungsten shop lamps can be a real challenge.

It is particularly hard to photograph polished brass under these conditions. So this weekend I set out to build a flash diffuser to improve the quality of the photography on this site. Most of the diffuser is made with foam board and packing tape. I laid out a square 30" inches on a side and then drew a cut line from each corner to the center of the top line. This gave me two right triangles that when taped together matched the center triangle.

I cut two sheets of foam board in this manner. When all of the pieces where taped together I had a square "horn" shape. These signs are also a great source for small to medium sizes pieces of coro-plast. Next I taped a piece of acetate about halfway up the "horn" and I built a support from two pieces of wood and some more foam board which I glued in place with carpenters glue. The light is very even. Here's my first test. How IR X-Ray Vision See Through Clothes Clothing Works. Reflected "See-Through" Perhaps you are wondering what makes this ability possible. The answer lies in infrared rays. All reflected light that we can see with the naked eye represents a fractional portion of the electromagnetic spectrum, which is infinite. We refer to this section as "visible light".

The visible part of the spectrum falls between the wavelengths of 430nm~690nm. (1nm=10-9m) Infrared rays have much larger wavelengths than this. Unlike ultraviolet and visible rays, infrared rays tend to penetrate any medium rather easily because of their large wavelengths. The KAYA PF exploits this characteristic of infrared light. Almost all of the ultraviolet and visible rays are unable to permeate the fiber and are reflected back instead.

The PF is struck by ultraviolet & visible rays that are reflected from the cloth and also the infrared rays that are reflected from the mannequin's surface. Of course, if you were to simply look through the PF, you would not see anything at all. Free Digital Photography Tutorial Site - Great Photo Tutorials. Flaming Pear:Products. Enough already with the megapixels. Generally speaking, the march of technological progress gives consumers what they expect. More stuff for less money, all the time. Hurrah. Sometimes, though, some segment of the high-tech industry gets caught in an unprogressive eddy for a while. And it's usually the fault of oversimplification. As Albert Einstein said, everything should be made as simple as possible, but not simpler.

Take IQ, for instance. In computing, there's clock speed. And so it is with digital cameras. The truth can actually, quite often, be exactly the opposite. Consumer digital cameras always have teeny tiny little sensor chips in them. Eight million pixels on something the size of a Rice Bubble means, of course, that the pixels are very small. For comparison, the Canon EOS-5D, the cheapest DSLR with a full 35mm-frame-sized sensor, has a 12.7MP sensor, but 8.2-micron photosites. So what, I hear you say. And yes, actually it does. What this means is that the signal-to-noise ratio of bigger photosites is better. Digital Camera Tips and Reviews: Photonhead, The Essence of Modern Film and Digital Photography. BackLighter. Also open part 2 now in a second window Ohhh... It's so easy--and I was making it so hard! Over a year ago I began trying to work out a cheap and easy way to scan 35 mm slides on an ordinary flatbed scanner--to avoid buying the Transparent Media Adapter for several hundred dollars.

This is the third--and, I think, the final--stage in figuring out how to do the same job for free. (If you're curious, links to my two previous methods are on the Scanning Experiments page.) (Oops! As I said, it's so simple! I picked it up and looked underneath, expecting to find evidence of electo-optical wizardry in there. WOW--it was completely empty--just a right-isosceles-triangular plastic box, open on the hypotenuse side, with two bits of shiny sheet tin-can metal lining the two other sides. Naturally I had to try this for myself. Okay, okay, I'll spare you the rest of the story: it works great. BackLighter Here's how to make one for yourself in a few minutes.
