Infinite, with a suitable lens. In theory, a pinhole camera (which has no lens at all) will have a nearly infinite depth of field, but at the expense of extremely long exposure time.
What is an pinhole camera?
The most common type of pinhole photography is done with the aid of a shoe box. The film (use real black and white film as it is less sensitive to light and light leaks because we are talking about a shoe box here) is taped to one end of a shoe box and a small pinhole is carefully punched into the center of the opposite end of the shoe box. The box lid should be placed on tightly and sealed in place. When you handle the film, you must try to have total darkness. Practice all aspects of putting your shoe box "Camera" together in the light first. Place your finger over the pin hole before bringing into the light. Then the box is placed, usually outside on a sunny day. Point the pinhole end of the box toward something that you are interested in taking a picture of. Your subject has to be something that is stationary. The light coming through the pinhole will expose your film for you. Research the subject to help determine pinhole size and approximate exposure times to take some guesswork out your project.

How old is the oldest photograph?
The world's first photograph was taken by Joseph Nicephore Niepce in about 1826. It was an extremely long exposure by today's standards, over 8 hours. The pewter plate that was used wasn't nearly as light-sensitive as today's films or digital sensors used in modern cameras. The camera consisted of an entire room that had been sealed from light. There was a pinhole in one end that allowed light from the scene to enter and strike the plate, forming an image on it. The link below will allow you to view the world's oldest Photograph.
How long would the exposure time have to be to create a star trail photograph?
The length of time required to photograph star trails varies depending on how long you would like the trails to appear. Generally, with a 10 minute exposure, you will have very faint trails. With a one hour exposure, you will have trails roughly four times as long. With a 180 minute exposure, you will have trails that are substantially longer, and will noticeably fill the picture. The longer the exposure, the more white the picture will become as it is filled with star trails.
What is the significance of the bulb mode in photography and how can it be effectively used to capture long exposure shots?
The bulb mode in photography allows the camera shutter to stay open for as long as the shutter button is pressed. This is significant for capturing long exposure shots in low light conditions or to create motion blur effects. To effectively use bulb mode, a tripod is recommended to prevent camera shake, and a remote shutter release can be used to control the exposure time precisely. Experimenting with different exposure times can help achieve desired results in long exposure photography.

Why did Victorians never smile in photos?
Early photography depended on long exposure times, so the Victorians had to sit for minutes for their portraits. It's easier to hold your mouth shut than to fix a smile. Later in the Victorian era, exposure times reduced to a few seconds.
