This tool helps you determine the range of focus in your photos based on your camera settings. It calculates the near and far limits of sharpness, allowing you to control the area in your image that appears in focus.
How to Use: Enter the focal length of your lens, the aperture setting (f-number), the distance to your subject, and select your camera's sensor size. The calculator will show the hyperfocal distance, the near and far limits of the depth of field.
Long Exposure Time Calculator
This tool calculates the required shutter speed when using a neutral density (ND) filter for long exposure photography in daylight. It helps you achieve motion blur and other creative effects.
How to Use: Enter the shutter speed you would use *without* the ND filter, and then enter the strength of your ND filter in stops (e.g., 10 for a 10-stop filter). The calculator will determine the new shutter speed needed with the filter.
Megapixel to Print Size Converter
This tool helps you determine the maximum print size you can achieve from your digital photos without sacrificing quality. It uses the number of megapixels in your image and the desired pixels per inch (PPI) for the print.
How to Use: Enter the number of megapixels of your image and the desired pixels per inch (PPI) for printing. A higher PPI results in a sharper print but requires a smaller print size. 300 PPI is generally considered excellent quality for prints viewed up close.
For high-quality prints, 300 PPI is generally recommended. Lower values can be used for larger prints viewed from a distance.
