Most RAW photo files contain an embedded thumbnail image which can be used by Asset Bank for a variety of purposes.
Asset Bank has a setting that allows you to decide how small the thumbnail images can be (relative to the original) in order for them to be used in place of the full image.
If the embedded thumbnail is too small, the experience of browsing, searching, previewing and downloading these assets within Asset Bank might be compromised.
If you are finding that your RAW images (e.g. DNG, CR2, NEF, ARW, etc.) are not displaying the correct thumbnail (i.e. displaying the original image rather than a cropped version that you have set) then you will likely need to change this setting to a lower value:
The default value for this setting is 0.9, meaning the embedded thumbnail has to be at least 90% in terms of resolution compared to the full RAW file before it is used. If you decrease this to a value such as 0.5 (50%) then this will make is much more likely the customised thumbnail is used.
This setting is controlled in the ApplicationSettings.properties file, so if you are using the Asset Bank cloud hosting you will need to contact our support team in order to have this setting modified.
