Common fixes

All the images and videos you save into Artemis are secure and only visible to you, unless you share them. We cannot see anything you save with Artemis, unless you share it with us. Artemis uses the Apple security protocol, which is very robust.

Without granting these permissions this will likely not perform properly.

Camera — Artemis needs access to the camera to show an image on the screen.

Microphone — when recording videos, access to the microphone is required. Disallowing this might cause issues playing back saved videos.

Photos — Artemis & Artemis Studio save images to a local data folder. We offer a back-up option to the Apple Photo app gallery, which requires a permission. We also use email functions which are tied in with the use of Apple's Photo app. To add reference images in Gallery, Artemis also needs access to Apple Photos. These permissions are all “internal”. Giving permissions does not compromise your security in any way and just lets Artemis use resources to give you the best user experience. We never have access to any of your data, unless you explicitly share it with us.

Location — this is required to geo-tag any images you take. This is essential for use with the Helios and Helios Live-View functionality in Artemis.

Very accurate, providing the focal length value being used is also accurate.

ALL lenses have marked focal lengths that differ from their actual, measured focal lengths. This variation may range from slight to extreme. Some lenses in common use have marked focal lengths double their measured focal lengths, mainly for marketing reasons.

If Artemis appears inaccurate this is most likely the cause. To remedy this you can use the Add Lens function and include more accurate data. Many discerning camera operators do this to make Artemis 100% accurate.

Most of the time it will be. But sometimes the published field of view of the iPhone camera is not exactly accurate. To fix this, use the camera calibration wizard you'll find in Settings.

The place to hold your iPhone is at the lens nodal point, which is one focal length's distance in front of the image plane, where the angle of view of the lens is measured. Since you are comparing two cameras with very different flange focal depths, a comparison at the nodal point will give you an accurate result. For zoom lenses, about a third of the way down the lens is best.

A few things to check first:

Does your iPhone or iPad have adequate storage space available? We recommend at least 20% free storage space.

Does your iCloud account have adequate storage space? If it is full, either purchase more space or remove as much data as you can to free up space.

Lack of storage is the #1 reason Artemis users have issues.

If you have plenty of storage space, you may have inadvertently changed a setting.

Open the Gallery Settings (the cog symbol on the left). Do you have Save Locally Stored Assets to iCloud Drive selected? If not, let's start here.

If you have adequate iCloud storage space, turn this on. If this was turned off and your images were backed up to iCloud, this is most likely the reason your images have disappeared. This might take a few minutes and an internet connection. If not, email us and we'll figure out what is going on.

This is the best option to protect all your data when using Artemis and required if you intend to use Artemis Studio for Mac. All your assets will be backed up in the Artemis Local Data folder. You can find this using the Files app on your device. This in turn will be backed up securely to iCloud.

Open the Artemis Gallery (bottom left), then tap the Settings cog. Turn Save Locally Stored Assets to iCloud Drive on.

In the Gallery, it is possible to view videos, images or both together. You can select this on the bottom left of the screen.

There are four options here. The quickest is to update the Camera Database and Lenses. The database is updated frequently and the Camera Format you need might be in the update.

If not, create a Custom Camera. Open the camera picker and scroll to the bottom of the page, then tap Custom Cams. On the top right tap Add Custom Camera and add all the details for that format. BEWARE! Camera manufacturers are often a little "generous" with their specs. Try and get some independently verified data rather than relying purely on the manufacturers data. Save this and you are set to go.

If you are prepping a job and have a little time, send us an email with as much information about the Camera and Camera Format you can. We'll add it as soon as we can get the data required.

Lastly, try a generic camera format as a stop gap until you have the data to make a custom camera or share it with us.

Open the Lens Picker on the top right and tap Add Lens at the bottom of the Focal Length list. Add new focal lengths here. The Marked Focal Length and the Measured Focal Length should be the same, unless you have measured the lens and have more accurate data. The anamorphic squeeze ratio for spherical lenses is "1".

Apple has restricted the use of UVC on the iPhone. Until that changes, the workaround is to use an Accsoon 4K SeeMo, which allows the HDMI output of the camera to be converted to data that the iPhone can display. This may change in subsequent versions of the iPhone or changes in iOS.

External Camera Mode requires a high-bandwidth USB-C cable. Not all USB-C cables support the bandwidth required — if it isn't working, try a different cable.

Try restarting your camera and checking that the settings for USB-C output are set to UVC, Streaming, Webcam etc, but not Storage or Power.

Check that the USB-C input on your iPad is clean.

Failing this, email us.

The Stream function in Artemis creates a local peer-to-peer connection to other Artemis users under 100 feet away (30 meters). Tap the Screen Share icon on the bottom right of the main UI to get started and follow the on screen instructions.

If you want to share your own screen, tap Share Stream and select the users to stream to. They also have to have Artemis running, and must select Watch Stream to join. And vice-versa.

If you want to stream to the on-set monitor, connect an Apple TV via HDMI and download the Artemis TV app. You can now stream Artemis directly to the on-set monitor using the same method as streaming to devices.

To do this you need to use FaceTime, WhatsApp, Zoom or any other similar application that allows for screen sharing. First set up a call, allow screen sharing in the app and open Artemis. Be aware that any notifications or messages on the screen may also be visible to those you are sharing with.
