The shadow against the cloud is really interesting
How low in the sky was the sun? That’s so cool that you were able to capture the shadow going upwards.
great colors very impressed that this doesn’t come from photoshop. The shadow-like effect of the trail is awesome
Wow, having the shadow of the contrail on the clouds looks just so cool!
The shadow from the contrail is really cool
It’s really cool that the shadow is passed onto the super high altitude cloud above
