As I described in the one picture, I manually crop the wide image square (without cropping the one (shorter) dimension). It’s a time consuming process but can be made quicker by loading dozens of images into Photoshop at once, locking the crop aspect ratio to 1:1 and using keyboard shortcuts to save/close the images. One of the developers got back to me elsewhere and said that manually cropping is a bad idea because that can’t be replicated at runtime. But what really can’t be replicated at run time is taking my widescreen camera image and squeezing it down to a 1:1 aspect ratio. 🙄 (I.e. Training a model with a widescreen-source image using Stretch to: 640x640.) FWIW, looking at these pictures again, those bounding boxes I used in the examples are terrible and way too big. I am pretty proud of my model though, it can be very accurate with only a couple hundred images per class. Not exactly “[degraded performance](https://discuss.roboflow.com/t/cropping-feature-with-the-annotate-toolset/1497/2)” imo. --- _[View the full topic](https://discuss.roboflow.com/t/resizing-large-16-9-2688x1520-images-for-use-with-yolov5/1416)._
