Watch with English subtitles on. For street photography and snapshots, you should consider it almost mandatory to trim, or else it won't work. The era of boasting "no trimming" is over.
As an attentive subscriber to your channel, I have also been following this topic with interest. What you teach about cropping photos is very educational. If your time allows, I would be very grateful if you would look at the magnolia picture (in my community area) and give me a short constructive criticism. I cropped the photograph relatively radically because there was a building with scaffolding in the immediate vicinity on the left side of the courtyard and the rear facade of a house on the right, both of which disrupted the main motif enormously. As a result, I had to trim part of the crown of the tree. I also wanted to incorporate the “Golden Ratio” as much as possible. As an experienced teacher, you will certainly be able to judge very well whether I succeeded in cropping the photo or whether, for example, I could have trimmed the left side even more. Kind regards - Monika
Your magnolia tree photo, I think the trimming has been generally successful. Personally, I might have trimmed a bit more on the left side, and also a tiny bit more at the bottom. Because of trimming the canopy, the area near the ground looks a little bare. Have a nice weekend, Monika
