How to Create Impossible Images with the Help of a Projector
Everything is invented and yet we invent new things every day. Taking photos becomes something more when the images we take are unique and we know that no one has ever done anything like it. We create and try new things, that we have seen or that we have dreamed, and that now we want to translate reality in front of the camera.
And that is what this article is about, projecting some forms, an idea or a dream image and merge it with reality, creating impossible photos alone. It is something so simple and with so many creative possibilities that I am sure it will encourage you to unleash your imagination to prove it. We just need to connect our computer to a projector and dump the images in our scene. Follow us at www.heimkinoleinwandtest.de/heimkino-beamer-test ?
And it is that our imagination is the only limitation here. Having a search engine for images online or a program of drawing or graphic design, we can choose at our whim what we will project in front of our camera. And from there we can combine it with an object, a model, another image or whatever we want.
“How?. Is it something like doing a double exposure on the sensor? Or would it be the same as superimpose the images with Photoshop ?. “Not at all. The result projecting the images on our scene will be very different as they are printed on the volume of objects , so that will naturally on its surface, Its curves, its imperfections … Thus, in a face, a body or a chair, the colors will look like they are painted right above.
Without large disbursements
Of course, a projector is not a regular part of our photographic equipment. But it should not be uncommon to have one on hand for presentations at work, a relative who uses it to teach vacations, or a friend who has one for home theater. And if it is not the case, given the large decline in the price of these teams in recent years, you can buy a basic projector with 640×480 resolution and 800 lumens for less than 60 € . They are very basic specifications, but for our purpose they are more than sufficient and also can serve us for many other purposes in the future.
Prepare the image and the stage
We will start by visualizing our idea and thinking about how to make it happen. For this we will have to calculate the space that we have to make the photo and the shot that has our projector. The shot is the distance to be placed to give a projection of the size we need, as the cone of light grows as we move away, and the angle of this cone is limited by the model of the device. And then we have to ask the questions that lead us to our goal: What kind of image we need to project ?. Do we already have it or will we have to create it? Will we use a model or mount a scene with objects? .
The first two questions will determine if we need to make a previous photo before taking the photo in question or maybe create it with an editing program. For example, in the header image, not a single image has been used, but an image with just black and white horizontal bars, with the intention that the black acts to hide instead of painting. Which brings us to another question: Will we need white background so that the images appear in the background, or black background so that nothing appears in the background, only on the model ?. These two options will not give completely different pictures.
Upload the ISO and help yourself with a tripod
A turning point of using a projector is that we can not be in a bright room and of course outdoor daylight, for every additional light eclipse the projector. Here it will depend a lot on the light power of the projector, as a small one can give 800 lumens while a large one can give up to five times more, about 4000 lumens. The more powerful, the more light it will give us on the scene and the better it will illuminate, which will allow us to use a lower ISO.
What is almost inevitable is that we have to raise the nominal ISO of our camera , because even with the most powerful projector, we’re talking light output far from a flash. It would not be uncommon to have to use ISO 3200 to get a good exposure, assuming that the diaphragm does not let a maximum aperture lest we limited depth of field and shutter at a moderate speed.
And this last point is recommended that, as we walk more than enough light, we use a tripod to make stable pictures as slow as possible , so we do not have to resort to the maximum sensitivity of our camera sensor. However, it is likely that, like me, you find that it is often difficult to reconcile the space to bet the tripod with the camera without obstructing the projection, because the projector will have to put it at a distance. Therefore, we may have to use long focal lengths to place ourselves at the height of the project.
What do you think? Do you dare to create photos with a new light source? If you throw yourself, do not forget to leave us your experience and results, I am sure that no two will be alike.
