How many professional photographer apps do you have?

After discussing the use of low-end cameras, most people actually use iPhones to take photos, so here we would like to share some practical and convenient apps for you to use.


Although, currently basic cameras and professional digital cameras have built-in metering, but in some areas of expertise, they still use mechanical cameras or cameras with no built-in light meters. Professional photographers generally will have incident or reflective hand-held light meters to monitor the light. This app is very convenient if you do not have a hand-held light meter or you did not bring your heavy equipment. Besides being able to customize ISO, there are aperture priority and shutter priority options, as well as custom exposure compensation.

Advantages: The interface is simple, it can display EV values, and it’s free!

Disadvantages: It only has reflective functions (if you need incident light meter functions, a photometer head can be purchased separately to be used with other apps).

iDoF Calc

Most commercial goods photography requires Panoramic functions to facilitate subsequent post-production or synthetic use. In the past, mechanical lenses will have depth of focus markings, and as long as it is compared to the shooting distance, the diaphragm can indicate the depth of focus range. However, after the digitalization of cameras, the depth of field indicators disappeared on the lens, and we could only know the depth of focus through experience or calculations. iDoF Calc provides depth of focus calculation functions and can calculate foreground depth according to the 3 parameters that affect depth of field: sensor size, diaphragm, and shooting distance to calculate the shallow depth of field, deep depth of field, and depth of field range.

Advantages: It has a simple interface and it’s free!

Disadvantages: Although there are a variety of brand model sensors to choose from, but the database lacks information on high-end camera sensors.


SkyView is a star simulation software that can use iPhone cameras to show astrological positions according to the user’s location and the date of observation. For photography, it can be used to track the movement trajectories of the sun and moon, and you will be able to predict the position of natural light sources while shooting or during site surveys.

Advantages: In addition to being able to observe sun and moon movement trajectories, it also shows the stars at night for free!

Disadvantages: The daylight movement trajectory has a 3 degree angle difference with reality.

645 Pro MK II

The professional shooting app can instantly display ISO, diaphragm, shutter, exposure histogram, high light and shadow exposure warning, spot metering / pattern metering, self-timer, WB/AE/AF luck, anti-shake, a variety of film options, built-in film color modes, and gradient light-reducing filters. You can shoot JPG + TIFF files, with the largest TIFF each about 25MB.

Recently, Alex Koloskov also compared the iphone5S +645ProMK II and Hasselblad H1 + Leaf machine. You can check the results.

Advantages: If you have too much information while shooting, you can shoot in the JPG + TIFF formats.

Disadvantages: The file reading speed is slow, and AE/AF/WB luck is the same option on the screen so you need to select it three times before completing setup.

Pro Cam 2

Another professional photography app, James’ main iPhone shooting software, has a variety of shooting modes (single/night/anti-shake/self-timer/video/time-lapse …), a variety of film options, manual exposure compensation, manual white balance, built-in contrast settings with a variety of filter functions, separate selections for exposure and focus and independent locks, and can shoot low compression JPG and TIFF files.

Advantages: Manual exposure compensation, manual white balance, independent exposure and independent focus lock, and can be used to make videos.

Disadvantages: File reading speed is slower


A very powerful color toning app, and although the software has built-in social group and camera functions, but the most powerful feature is the color toning function. VSCO has built-in a variety of filters, where you can adjust color yourself, or adjust exposure / contrast / saturation / rotation / crop / color temperature / tone / shadow enhancement/ brightness reduction / dilution / shadow chromaticity / light chromaticity. You must definitely try this app if you need to retouch many photos.

Advantages: There are rich toning functions, the interface is simple, and although there are other post-production apps that can adjust curves, but it is very troublesome to adjust curves on iPhones.

Disadvantages: None encountered yet
