LxMeter

Note: This is the trial version of LxMeter Pro, some functions might be limited

This application turns your phone into a powerful instrument with the following functions:

★ LUX METER

★ EXPOSURE METER

★ FLASH METER

★ SPOT METER

★ COLOR METER

★ FLICKER METER

As a luxmeter you can measure illuminance (density of luminous flux incident on a surface) from 0.1 to 3000000 lx. By using the app in "exposure meter" mode you get an easy to use incident/reflected light meter and you can determine the proper exposure for a photograph.

LxMeter supports measurements of flash lights and can display the percentage of flash in total exposure.

LxMeter can also deal with landscapes or other distant objects by running its spot meter mode; you can measure luminance (cd/m2 or foot-lambert) and correlated color temperature (CCT).

A powerful analysis tools has been added to LxMeter in order to evaluate flicker performance of a light source according to IEEE 1789. You can detect harmonics up to 30kHz, display the frequency spectrum and get all the parameters commonly found in professional flicker-meters.

You can specify ISO speed and exposure time and let the app show in real time the optimal aperture value or set the aperture and read the exposure time. You can easily switch between shutter speed priority and aperture priority or just run the manual mode and take note of the exposure level indicator.

LxMeter allows you to add some notes to your personal archive. Exposure and location information will be added automatically. You can save all the notes about a photographic project in the internal archive and use them as reference later at the time of the final shots.

Please, note that for maximum performance this app requires an external sensor of the SS04 product line. As alternative you can use the internal light sensor of your phone (if it has one) but in this case the accuracy of measurements will vary depending on the phone. For more details about SS04 please see http://www.optivelox.com/DL_en/ss0x.htm

注意：这是 LxMeter Pro 的试用版，部分功能可能会受到限制

此应用程序将您的手机变成具有以下功能的强大乐器：

＆＃9733;照度计

＆＃9733;曝光表

＆＃9733;闪光计

＆＃9733;点仪

＆＃9733;颜色表

＆＃9733;弗利克米

作为照度计，您可以测量0.1至3000000 lx的照度（入射在表面上的光通量密度）。通过在“测光表”模式下使用该应用程序，您可以轻松使用入射/反射测光表，并可以确定照片的正确曝光。

LxMeter支持闪光灯的测量，并可以显示闪光灯在总曝光量中的百分比。

LxMeter还可以通过运行点测光模式来处理风景或其他远处物体。您可以测量亮度（cd / m2或英尺朗伯）和相关色温（CCT）。

LxMeter中已添加了功能强大的分析工具，以便根据IEEE 1789评估光源的闪烁性能。您可以检测高达30kHz的谐波，显示频谱并获得专业闪烁计中常见的所有参数。

您可以指定ISO速度和曝光时间，并让应用实时显示最佳光圈值或设置光圈并读取曝光时间。您可以轻松在快门速度优先和光圈优先之间进行切换，也可以只运行手动模式并注意曝光量指示。

LxMeter允许您向个人档案中添加一些注释。曝光和位置信息将自动添加。您可以将有关摄影项目的所有注释保存在内部档案库中，并在以后进行最终拍摄时用作参考。

请注意，为获得最佳性能，此应用需要使用SS04产品系列的外部传感器。作为替代，您可以使用手机的内部光传感器（如果有），但是在这种情况下，测量精度会因手机而异。有关SS04的更多详细信息，请访问http://www.optivelox.com/DL_zh/ss0x.htm
