Go ask them! There won’t be any problem :) people love having good photos of them, if not ig wouldn’t be so popular ;) people will be grateful for sure

In the middle of the day the light is very hard tho

• Golden hour for sure! The biggest game changer in nature photography

• If you can, make the subjects wear red clothes as it will contrasts really good with the green tones of the forest

-try to place the subjects in the middle of the trees so that the sunlight rays can get to their faces

• Try to include the sunlight rays in your composition

• take a vertical shoot from the floor with big angular lens so the trees look enormous

Try making a name for yourself within the internet. Post and share your work in the media!
