Extra photos for bloggers: 1, 2, 3
Slide projectors are great but outdated. And digital projectors cost a bundle. What’s a photographer to do when they’re looking for a bigger picture?
We’ll show you how to turn your phone into a photo projector for just $1.
Yep, for a buck you can have Instagram on overdrive and Flickr living large.
The project is so easy, you might even have time to sneak in a cat video or two.
Why it’s Cool:
Just picture laying in bed browsing your feed or watching a movie on a ginormous screen.
A projector provides a new way of looking at your shots, and for $1, who can afford not to try this project?
- Magnifying glass (get it for $1 at Dollar Tree), or a large aperture lens
- X-acto knife or similar
- Electrical or black duct tape
- Matte black spray paint or black paper
Step 1: Trace a Hole on the Box
If the inside walls of your box are a bright color, you may want to spray paint them black or tape up some black paper for best image quality.
Once your box is ready, trace the outer edge of your lens or magnifying glass onto one of the short sides of the box.
Step 2: Cut a Hole in That Box
You don’t want light leaking around your lens so try not to cut too much.
At the back of your box, cut a small hole for your phone’s power cord.
Step 3: Attach Your Lens
If your magnifying glass has a handle, you may want to remove it first.
Line up your lens with the hole and apply tape around the entire edge of your lens.
Make sure your lens is held securely and there are no holes between the tape for light to escape.
Step 4: Take a Stand
We used this very helpful tutorial to make a stand for our phone out of a paper clip.
Step 5: Flip Your Screen
When light passes though a lens (including the lenses in your eyes), it gets flipped, which means the picture from your projector will come out upsidown.
No fear though, we have a fix!
For the iPhone go to Settings > General > Accessibility and turn on AssistiveTouch.
Once activated, a little white orb will pop that you can drag around the screen.
Click on the orb and go to Device > Rotate Screen.
This will allow you to flip applications like the Photos app which would normally rotate itself right side up.
Andriod users can download the app Ultimate Rotation Control.
Or if all else fails you can just stand on your head.
Step 6: Finding Focus
For a screen you could use a white bed sheet, turn a poster around, project onto a shower or window curtain, or just use the bare wall.
Without a focus ring on your magnifying glass you’re going to have to foot focus.
Position your phone in its stand near the back of the box and walk forwards or backwards until your image starts to come into focus.
Once you’ve found a good range you can fine tune focus by moving your phone forwards or backwards in the box.
If you used a camera lens for your projector, you get the bonus of a focus ring that gives you some extra flexibility in terms of screen size and focus distance.
Step 7: Don’t Fight the Light
For best viewing, turn the screen brightness of your phone all the way up and turn the room lights down.
Set your phone’s photo app to slide show mode for a hands free experience.
Your power cord can go through the hole you cut in the back of the box and a little tape will seal the deal.
