How come the camera is square, the photos are square, but the lens are round?
Just wondering why? Like shouldn’t it be a square camera lens?
Good question.
First, lenses are naturally round. Making them square would be a lot of work, would ruin the quality, would be bigger, etc.
Second, film is naturally square (rectangular actually). Otherwise you would have a lot of waste space, etc. Plus it’s easier to visualize a square picture instead of a round one. Square film=square picture.
Third, the real question. Why doesn’t having a round lens mess up a square picture in some way? Isn’t this like putting a round peg in a square hole? Why does it even work?
This is the way camera optics work: light comes from the sun, light bulb, etc. and reflects off a point on an object. The reflection scatters in every direction. Cameras capture as much of this scattered light as they possibly can. The physics of a lens is such that when an object is in focus, all the light that strikes the lens gets bent while going through the lens in such a way that it all goes back to a single point on your sensor/film. This is the magic of a lens–it doesn’t matter where the light hits on the lens, it all comes from the same point and goes to the same point (only true while in focus of course). It does this for every point in the image, coming from a point ending up in a point. This is why the shape of the lens, whether it’s square or round, doesn’t matter. The curvature of the lens is critical however.
Review of my two month old Sony W300 camera.
http://live.pirillo.com – I am a fan of the Canon Digital Cameras, but not such a fan of their software. Whappo sent me an email to let me know about an open-source program called CHDK, which can be used to update the software for your Digital Camera.
amazing video showing puncture of baloon 80x slower.
With the Sony Cybershot DSCW330, take impressive, 14.1-megapixel photos with this compact digital camera. The Sony Cybershot DSCW330 Digital Still Camera captures amazingly detailed images with a 26mm equivalent wide angle 4x zoom lens. Reviewing your shots is easy on the 3.0″ LCD (diag.) and advanced features including Easy mode, iAuto and SteadyShot image stabilization eliminate the guesswork in tricky lighting environments on the Sony Cybershot DSCW330 Digital Still Camera. And don’t miss the handy in-camera retouching feature that corrects red-eye and trims photos.
I have a new camera and I’m testing it out. Listen and give me your feedback on the quality of this vid.
Part 1 of 2: I used Loctite epoxy putty to make a removable frame to hold a wide angle lens on a Kodak Zi8 video camera. I used epoxy, because it is not affected by heat as much as the moldable plastic you can buy online. I did not glue anything directly to the camera, nor did I have to take it apart to add a magnetic ring like a popular lens mod from china, so no warranty was voided and no damage occured to the camera.
Langley unboxes a couple of lenses made for the iPhone camera!
Canon EOS 550D Digital SLR Camera – Part 4 – The Review. Yes, this is the video you have all been waiting for… the main review. Here I take a good look at the camera including photos and video footage taken with the 550D.
http://kodakzi6review.blogspot.com. I love the Kodak Zi6 Video Camera, so much so, that I decided to do a review. This review goes in-depth in such a way that I hope it will help you in your decision to purchase. I don’t think you will be disappointed. I shot this review with a Canon XH A1 and edited in Final Cut Express.
