You don't need fancy glasses or equipment to enjoy one of the sky's most awesome shows: a solar eclipse. With a few simple supplies, you can make a pinhole camera that lets you watch a solar eclipse safely and easily from anywhere.
Your pinhole camera will let you see an image of the Sun that is safe to look at. But remember to never look directly at the Sun without equipment that's specifically designed for looking at the Sun. Note that sunglasses, binoculars, and telescopes do NOT count as proper protection.
Place your second piece of card stock on the ground and hold the piece with aluminum foil above it (foil facing up). Stand with the Sun behind you and view the projected image on the card stock below! The farther away you hold your camera, the bigger your projected image will be.
For a different kind of pinhole viewer, try printing out and building the SunRISE pinhole viewer (PDF) pictured above and modeled after NASA's SunRISE spacecraft, which are part of a mission designed to study space weather. (Printing on 11x17 cardstock is recommended, but other printer papers work, too.) As you build, learn about the mission's six toaster-size cubesats and how they will study solar activity, creating 3D maps of the Sun's radio emissions and magnetic field lines.
Light from the Sun enters the pinhole (or the holes in an object like a colander), it gets focused, and then it is projected out of the other side of the hole. When the projected light reaches a surface, like the second piece of paper, you can see the image that passed through the pinhole.
This nagging feeling, which I could never precisely put my finger on, eventually became self-diagnosed as the RUTS (Reliance Upon Technology Syndrome). This differs greatly from the more prevalent and conventional GAS (Gear Acquisition Syndrome) about which one regularly reads; a syndrome most commonly contracted by those who are newer to photography and often transmitted via YouTube videos, through the power of persuasive bloggers, or even contracted as a consequence of prolonged close contact with carriers of the disease from among the arrogant owners of the most exclusive (and expensive) cameras.
RUTS, however, is usually self-inflicted and routinely results from developing an unhealthy imbalance in the mind. It quite commonly affects those shifting away from film photography into digital photography.
Photographic success is determined by three primary, and fundamental, factors. These involve the skills learned and employed, the equipment, tools, and materials utilised, and that at which the camera had been pointed. Those suffering with the RUTS erroneously ascribe inappropriate weight to the equipment and allocate insufficient weight to the necessary skills; thus, establishing the imbalance.
This debilitating imbalance in our minds can cause confusion; what is genuinely important and necessary with what is not. The fact is, a camera is merely a light-proof box designed to hold some light-sensitive substance such as film (or a sensor) at a certain distance from a hole which can itself occasionally allow light to enter the box. How long that light streams into the box is determined by the photographer and controlled via the uncovering and covering of that hole.
Just these four factors remain requisite and indispensable: aperture, shutter speed, ISO, and focus. Nothing more of which a modern camera may be capable is absolutely vital for photography. Yet, a critically imbalanced mind tends to place an unwarranted high value on inessential accoutrements such as frames per second, crop factor, bracketing stops, dynamic range, megapixel counts, flash sync-speed, twisty-flippy screens, high-resolution optical viewfinders, live-view, shooting modes, histograms, focus peaking, (the list goes on, ad nauseam). As helpful as such may mistakenly seem in some certain situations, they remain entirely unnecessary to producing a photograph.
I find it odd that, although lens manufacturers constantly tout the enormous apertures accessible on their new lenses and the absolute necessity of obtaining the narrowest depth of field, none seem to be trying to design and offer lenses which would provide a greater depth of field (something we often do need). Although shutter speeds have incrementally accelerated for each passing decade, no company is offering a solution for setting exact slow shutter speeds (such as 14 minutes and 38 seconds). Nor have they created sensors which can capture such long exposures without dissolving into noise (although they seem to double the highest purported ISO numbers every other year).
Autofocus boasting astronomic arrays of focus points are all well and good but that which went before was never really all that good anyway. Besides which, when I use autofocus, I only ever need or want one focus point placed right in the middle of my frame and I have always found f/5.6 and f/8 to be lovely apertures that do not demand such pin-point focusing accuracy.
Since that eureka moment, I have shot more with my Olympus Trip than with my Panasonics, more with my Pentax ME and Canon FTQL than with my Canon 600D, more with my Yashica TLR and Minolta 9xi than with my Canon 6D. In doing so, proper balance was returning to my mind. Yet, I perceived something still out of kilter. I continued to be hindered by the sometimes subtle interventions of even these cameras. I sought some way of return to the four basic controls exclusively to allow me to concentrate solely on exposure and where I ought to point my camera; some remedy to free me from the RUTS.
Now, I cannot afford a Leica M3 and I sincerely doubt anyone is ever going to offer to give me one (the majority of the film cameras in my arsenal were bought used for a song). So, that left me with my FTQL or 124 G (sans batteries) or my Praktica PL Nova 1b (with its sometimes seemingly dead selenium cell). Or my ME (in 100X mode). Until, that is, whilst wandering the interwebs one fateful morning my eyes fell upon an image of a simple black box which piqued my interest in a way in which no other camera manufactured in the last 20 years ever had. It felt as if I had identified the cure for what ailed me.
It gives me the unlimited opportunity to be the photographer. It places my ability to achieve proper creative exposure equally alongside my deliberate decisions about at what to point the camera into their rightful position within the equation, thus removing the camera itself from the formula. It reduces my choices and concentrates the universe down to pointing the camera at what I want to photograph and determining the shutter speed to use. In that moment it neither offers nor involves any other options.
The experience of shooting that first roll was nothing less than liberating. Sort of. Twisting two captive screws removed the top plate, allowing for quick and straightforward loading of the film. But even after years of honing, my Sunny 11 Rule skills (a much-needed Swedish modification to the more equatorial Sunny 16 Rule) were not able to calculate the f/160 aperture and the Reciprocity Failure factor of the film. Fortunately, whilst awaiting the arrival of my package from France I had downloaded the Pinhole Assist iPhone app which James had recommended on his website. But even with the aid of this tool, the exposure decision-making process remained firmly in my hands.
The icing on the cake, the cherry on the top, the stroke of pure genius is the sliding magnetic shutter enabling shake and vibration-free operation; simply cover the magnetic shutter-slide with a finger on one hand, slide open the shutter with the other hand, and quickly move that first finger out of the way. Reverse the procedure when the exposure is complete; quickly cover the pinhole with a finger on one hand and slide the magnetic shutter-slide back over the pinhole with the other hand.
I am fully aware that these first humble photographs which I have created will garner nothing in the way of recognition, awards, or income. But, it was I alone who created them without the electronic assistance, or hindrance, of any abstruse algorithms devised by camera company boffins in a laboratory somewhere. They are without doubt my most utterly exciting and satisfying two outings in quite a long time.
Does this mean that everyone ought to abandon all of their digital gear or even any feature-rich analogue gear? No, that would be missing the point. What I hope to clearly communicate are the benefits of limitation in remediating and redressing the excruciating effects of RUTS and to candidly convey the enjoyment and gratification to be found in simplicity.
This examples requires that CAMERA permission is requested at runtime and enabled in your project's Manifest Settings (Edit > Project Settings > Magic Leap > Manifest Settings).
The script below is more complex and uses the Async functions to prevent performance issues when starting and stopping Camera capture. The example only supports a single Video capture stream. To use it, add the script to a GameObject and then call StartCameraCapture to start the the camera capture. This examples does not render the output.
setup works with several cameras, just make sure you have the correct one assigned to current Camera. The Zoom inputs are mapped to actions that use MouseWheel and the factors are 1.1 for zoom out and 0.9 for zoom in.
