Hi, Kindly read this article.

Opening photos into Camera Raw

For a smooth workflow, we recommend setting the proper preferences so your raw photos (and JPEG or TIFF photos, if any) will open directly into Camera Raw.

To set a preference so your raw photos open directly into Camera Raw:

1. In Photoshop, go to Edit/Photoshop > Preferences (Ctrl-K/Cmd-K) > File Handling.
2. Under File Compatibility, check Prefer Adobe Camera Raw for Supported Raw Files, then click OK. When you double-click a raw file, it will open into Camera Raw (as opposed to other software that can be used to convert raw files).

• At the bottom of the dialog, from the JPEG menu, choose Automatically Open JPEGs with Settings.

• If you shoot digital TIFF photos, from the TIFF menu, choose Automatically Open TIFFs with Settings; or if you shoot only raw or JPEG photos (not TIFF photos), choose Disable TIFF Support.

• Click OK. 

• If the Open in Camera Raw button is available when you click a thumbnail in Bridge, it’s a sign that the file can be opened into Camera Raw.

• Check Double-Click Edits Camera Raw Settings in Bridge if you want Camera Raw to be hosted by Bridge when you double-click a thumbnail in Bridge (a raw photo or a JPEG that was previously edited in Camera Raw), or uncheck this option to have the file open into Camera Raw hosted by Photoshop. Click OK.
