Modern tablets and phones allow apps to hook into the camera abilities for streamlined use, but there may be times you prefer to directly access and use your camera app. Here's an overview of two ways you might take pictures on mobile phones and tablets while inspecting, for various purposes.

Launch Camera within 3D Mobile Inspector
When you use the photo icon button within the 3D Mobile Inspector app, this launches your camera app from 3D, and after you take an accept a picture, the camera app returns the photo to 3D Mobile Inspector where it is embedded into your report where inserted.  Although small devices line phones only run the 3D Mobile Inspector app in portrait mode, you may use the camera in landscape and the photo will be appropriately inserted that way.

For normal narrative reports, you may insert as many photos as needed this way simply by taking additional photos while on the appropriate field. This method eliminates extra steps to insert photos into a report for efficiency. Such photos stored within the report are automatically included when your report is sent back to the cloud.  Easy Peasy!

It is also possible to retrieve photos from the mobile device's gallery. Photos taken within 3D Mobile Inspector are automatically stored in the mobile devices gallery.  By default the newer 3D Mobile Inspector app also stores the photos in the Gallery as well.  For photos you may not want to include in your report, but want for informational or other uses outside of your report, you may find it convenient to just take those pictures directly with the camera app outside of 3D Mobile Inspector.

Launch Camera app directly
If you take pictures directly with the main camera app (not tapping the camera button in 3D), then they go into your normal Camera/Pictures/Gallery app on your phone. One may usually access the camera by pressing the shutter button, or opening Camera from the app menu. Such photos are then accessible in the regular Camera Gallery, and would usually be be transferred separately using your regular device options, many of which offer automatic cloud syncing. See your device documentation for further information about retrieving or syncing photos directly from a device.

Photos taken separately in your camera app may also be further annotated on your device and inserted into 3D reports afterward, whether on your device or in the desktop softwaare, as discussed in another article:
This may also be handy for taking additional photos for personal reference that you don't wish to include in your main report for clients.
Later you may still choose to archive a group of outside photos (or even a few short videos) along with your report file for organizational purposes if you attach the file(s):

With these various options available, you can mix and match the steps and features that work best for your particular work flow and organizational style!
