The most reliable technique to shoot web is a DSLR. For instance this week i have been shooting web but i'm not using DSLR for this. My main camera is a Nikon D810 which has great video performance and is very compact. If you prefer using a smartphone you can simply use the smartphone software like Adobe's camera apps. But since my camera is compact i use a different app called MOTOJAX for editing pictures.
For our purpose we are going to use the free version of Adobe Camera app and the version of MOTOJAX for editing photos (3.9-4.4.x).
To shoot using the MOTOJAX you have 3 options:
Open the app in the browser
Download web
Import images to your phone
Camera Settings to use the iPhone app on MOTOJAX
If you are shooting video on camera you should make sure that the video is recorded in the native iOS video player of your phone like Adobe Camera Camera Roll, iMovie etc. If you are using Android or a custom camera app like Samsung Camera you should download the app in those apps directly rather than importing it to Camera Roll and then using this app to edit pictures.
On my phone i can open the app in any of the following ways:
