My Experience Using This Tool

The result looks really nice. The new flowers blend well with the original picture.

I was surprised to see it even added pink and purple flowers around the yellow one, which wasn't there before. But it actually made the picture look even prettier.

How about other images?

I decided to try another portrait photo as well. I cropped it in half and fed it into this app to see if it could generate something similar, or perhaps even better.

▲ The AI seemed to confuse the hat with her hair. Nevertheless, the hair extension looks very stylish.

I attempted twice with the same photo above. The AI was able to extend the face, clothes, and even the blurry background. YouCam Enhance’s AI Image Expansion performed exceptionally well in naturally extending images.

▲ Its background was extended with prominent blooming flowers.

Take a look at the result. The image was extended similarly, but now it features even more noticeable flowers, giving it the appearance of an artistic painting.

However, the size of the generated flowers seems a little bit unnatural given their distance in the photo (Just a tiny flaw, not affecting the overall performance).

It automatically generates 4 results at once. I don't have to run it again if I'm not satisfied with the previous one.

Sometimes the generated parts appear blurry. I think it's because there is a blur effect in the original image, and the AI attempted to replicate similar effects. It means that its AI can not only extend the background but also create effects.

If you're a photographer, this tool can assist you in enhancing the background of model images with realistic results.
