Camera Quality for photos are great, but the details are just too soft and gone...
Asus, Improve the camera software processing and bring all the details and sharpness, lost all the details from my pics and not great as the camera specs it self
if you want take a very good picture quality i suggest you using a Full Frame Mirrorless or Full Frame DSLR Cameras rather than using a small sensor size that many Smartphone camera has.
BUT, if you want a Maximum photo quality through your Zenfone 3 ZE520KL, then i suggest you to shoot RAW with DNG Format. You can use Adobe Photoshop Lightroom to shoot RAW picture and save it to DNG format and developing it later whether on your PC (Adobe Photoshop) or with the same App (Adobe Photoshop Lightroom) or Snapseed App (i find this has much better image control for tweaking your final photo result).
