Homework Help Overview

The discussion revolves around the effects of pinhole size on image formation in pinhole cameras, exploring how different sizes and configurations of pinholes influence the characteristics of the resulting images.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the implications of small, large, and multiple pinholes on image quality, including depth of field and exposure. Questions arise regarding the nature of images produced by different pinhole sizes and configurations.

Discussion Status

There is an active exploration of concepts related to image clarity and exposure, with some participants providing insights into the effects of pinhole size on depth of field. However, there remains uncertainty regarding the implications of using multiple pinholes, indicating a need for further clarification.

Contextual Notes

Participants are navigating assumptions about depth of field in relation to pinhole cameras, with some suggesting that traditional photography concepts may not fully apply. The discussion reflects varying interpretations of how multiple pinholes affect image formation.

what kind of image is formed from the pinhole camera when the pinhole is small?what kind of image is formed from several pinholes?what kind of image is formed from a large pinhole?
how would i describe these images?

Hummm, photography 101 tells me that the camera with a small pinhole is going to produce am image with a large Depth of Field but at the cost of a darker image. The large pinhole will allow in a great amount of light but at the cost of a more shallow DOF. Not sure about the several pinholes one though...
 
I don't think depth of field is quite the concept you want since pinholes don't focus at any specific distance. Just plain blurry vs sharp is the distinction. For several pinholes how about "multiple exposure"?
 
thanks a lot!but what about the several pinholes?
