Par Meter & Spot Meter

专为工程师和摄影师而设计的Spot Meter和Par Meter。

spot meter or a par meter provides exposure setting calculation and depth of field/hyperfocal distance calculation.

par meter was designed mostly to use with film cameras, although the dof/hyperfocal function can be useful for digital cameras too.

spot meter also tries to take advantage of the ambient light sensor on the phone.

The exposure setting calculation using the spot meter supports three modes: aperture priority, shutter priority and manual mode.

data spot meter with spot metering (using the device's camera) and an incident light meter (using the device's light sensor) in one app

lux per meter Can be used for any type of camera from film SLR to pinhole to cinematographic.

In addition to the two meters, led par meter includes a Sunny Sixteen calculator and a Depth of Field calculator.

spot meter app is tested accurate against Gossen and Sekonic meters on most devices.

spot metering for photographers and movie makers that know their way.

light par meter can estimate depth-of-field, too.

hot spot meter uses the device's light sensor or camera to function as a portable spot meter.

Spot meter Calculates the Aperture or Shutter Speed based on light readings

Par meter app Calculate the nearest ISO value of the given aperture and shutter speed combination.
