Question: I'm looking for a user-friendly photo editing app that can enhance my under-exposed photos, any recommendations?

One top contender is Let's Enhance, an AI image enhancement service that can upscale low-resolution or blurry shots to high resolution. It also has filters for HDR, background removal and integration with APIs for business customers. It's fast and easy to use, and works well for creative pros, e-commerce and real estate customers who need to get image editing done quickly and with high quality.

Another top contender is Remini, which converts low-resolution photos and videos into high-resolution shots. With options to enhance faces, color, noise and background details, it can help with common photo problems like blurriness and focus. Remini also can upscale photos and videos without losing quality, and it's available as an API for easy integration into apps, so it's good for social media, preserving historical records and printing services.

If you want a more basic enhancement option, Media.io Img Sharpener offers AI-based image sharpening with options to remove noise, correct backlit photos and boost underexposed portraits. It can handle a variety of formats and image sizes, and it runs the image processing in your browser for privacy.
