How do i reset or clear the picture that was cached in the Camera1.Photo from a Camera Screen. This Camera1.Photo always contains the previous snapped picture.... and even if I am trying to ADD A NEW RECORD OF VISITOR, thisItem.Image which is supposedly blank shows the Camera1.Photo from the previously shot taken by the previous vISITOR who logged into the APP.

So for example, a new users registers in the app and right away, he sees a PICTURE of someone in his newForm's image (from the camera1.photo of previous user who registered)

Hi JenVitug

This probably depends on how you saved the image, you mentioned a chache, which indicates you may be working with collections? In that case you could use ClearCollect(collectionname) to clear the image saved in the collection for when a new user accesses the form.

This ClearCollect function could be embedded in the OnVisible property of the NewForm screen, or perhaps as part of the navigation when a user gets to the new form screen. E.g.

Navigate(NewFormScreen, Fade); ClearCollect(collectionname)

Curious to hear if that worked.

Hi @JenVitug,

Thanks for the feedback.

Currently for the camera control, there is no Reset property could be used to clear the .photo property, if you would like this property to be added in the future, then please consider submit it as an idea under PowerApps idea forum:

https://powerusers.microsoft.com/t5/PowerApps-Ideas/idb-p/PowerAppsIdeas

Further, to workaorund this, please don't use the Camera1.photo within an image control directly, as @Anonymous suggested, consider take use of a variable, then when naviagte to the EditForm, initialize the variable(collection) with blank value.

And, under the OnSelect property of the camera control, update the variable (collection) with the Camera1.photo value.

Regards,

Michael

Hi @JenVitug ,

You can use the following code:
For get the image:
UpdateContext({PhotosVariable: Camera1.Photo})
For clear:
UpdateContext({PhotosVariable: Blank()})

Obviously in the "IMAGE" section must be "PhotosVariable".

If it doesnt work try with: "Camera3.Stream"
but for this you need to put into "StreamRate" of Camera the value: "100"
