How to Make a Pinhole Camera Box

Pinhole cameras are some of the most basic kinds of cameras, and they can teach you a lot about how cameras and photo paper work. They're a great project for kids to make on summer days when there's lots of light. A pinhole camera's shape will often dictate your end result. A boxlike pinhole camera will give you a more straightforward and normal-looking picture than a cylindrical pinhole camera, so it serves as a good camera substitute when you want quirkier photographs.

Instructions

1

Choose your box. A shoebox will work well, but make sure that your box has a large lid.

2

Paint your box and its lid inside and out with black spray paint, and allow it to dry completely.

3

Cut a small hole, no more than 1/8 inch in circumference, in the center of one side of your box. If using a shoebox, cut it on the longer side of the box.

4

Cut a square piece of card stock about 3 inches wide and 3 inches high.

5

Tape all four sides of the card stock to the box. This piece of card stock will serve as your camera's shutter.

6

You will now be able to use your pinhole camera box. To do so, place a piece of photo paper emulsion side out in your box in a pitch-black room. Go outside, and pull the card stock away from the box--as you would when opening a door--to expose your piece of photo paper. Results will vary based on the amount of sunlight outside. You will be able to process your photo paper once you take the photo.

How to Make a JPEG Smaller

You might want to decrease the size of a JPEG image for many reasons. For example, you may want to place the picture on a website that limits the size of posted pictures or graphics. Making a JPEG image or picture smaller also makes the file smaller, allowing you to send it through email or store it on an external device, such as a memory stick.

Instructions

1

Open the image in Microsoft Photo Editor by either right-clicking the image file and selecting "Open With" and choosing Microsoft Photo Editor or open Microsoft Photo Editor, select "Open" from the "File" menu and find the image file you want to alter.

2

Select "Resize" from the "Image" menu, and reduce either the width or height, either by size or percentage, by changing the number in the corresponding space. Change the size in only one place, because the others will change automatically to avoid any distortion of the image. Click "OK" when you're finished.

3

Select "Properties" from the "File" menu to check the size of the image.

4

Select "Save As" from the "File" menu to save the altered image and keep the original image intact. Name your new image file and store it where you can find it later.

How to Set Dots Per Inch for Printing

Printing photographs requires a much higher count of pixels per inch, also called dots per inch, than simply viewing photographs on a computer screen or transmitting them over the web. The dots per inch, or dpi, value is the measure of the resolution of the image, or how clearly it will display, especially when blown up to larger sizes. To set dots per inch for printing, you will need image editing software. Adobe Photoshop is a good investment and the industry standard, but other image editing software will work as well.

Instructions

1

Ready the image for printing that you wish to set the dots per inch value for. This tutorial is using Adobe Photoshop, but the steps will be similar in other image editing software such as the GNU Image Manipulation Program (GIMP).

2

Find the "Image" tab in the task bar in the top left hand corner of your screen. Click on it to open the drop-down menu.

3

Select the "Image size..." option from the drop-down menu and click. You will now be taken to a window displaying all manner of information about your image. You are concerned with two factors here. The first is the "Resolution," which is your dots per inch value that needs to be set to the right dpi for printing. The second is the dimensions of the image, shown by default in "Width" and "Height," in inches.

4

Uncheck the "Resample Image" tab before changing your dots per inch value. You don't want to be changing the content of your image yet, just the way Adobe Photoshop recognizes it.

5

Change the "Resolution" variable, set to pixels/inch by default, to 300. The 300 dots per inch is the standard value to be used in printing. As you change the dots per inch to 300, if it is not at this value already, the image height and width will change on their own. Now that your dots per inch value is correctly set for printing, you are ready to resize the image to the desired dimensions.

6

Click the mouse on the check box for "Resample Image" so that this option is checked once again. Make sure the "Constrain Proportions" box is checked, so that you can resize the image without distortion. Set the image height to the desired height, and the width will automatically change. Now you have an image at the appropriate dots per inch for printing and you will have a clean, professional-looking print.
