Greetings. I've just aligned a set of multispectral images acquired using a parrot sequoia camera. In the photo panel in Photoscan, it is just displaying the green band for each image (not the red, red edge or NIR bands). The images for the green band are all very dark and it is extremely difficult, if not impossible, to see the GCP markers that I placed throughout the study area prior to the flight. Is there a way to display the other bands or can I somehow brighten the green images to facilitate the placement of markers in the images?

Thanks,
David

Hello David,

You can select which band should be displayed by using "Set Primary Channel" option in the chunk's context menu of the Workspace pane.

Also in the Photo view you can adjust the brightness, for example, set it to 1000% to make the images 10 times brighter.
