#303 LGV20 RAW image lower quality than JPG

[A. M.]

Hi Mark,
Congratulations on a great app. I really like it so far. The main issue I am facing is that the raw images generated on my LG V20 seem to be of lower quality than the JPG. This is an issue which was faced with the LG software as well as has been reported here: https://goo.gl/pnfZpT. However, in the case of your app, I am actually generating a larger image (4640x3476 with a file size of 31 MB). But the JPG file shows an image which is much sharper and there is lot of loss of detail in the RAW DNG file. To me it looks like the RAW is still 1 megapixel or something low. I am attaching the raw and JPG file for the same image as taken by the Open Camera software for you to compare. Please let me know if there is some setting which I am missing out on.

 Regards,
 A. M.

Update: so it seems that the files open fine if I use SnapSeed and they show a higher resolution version of the image.

Yes, especially if you set the exposure to an adequate level.

Just to clarify, can this be closed if it's working fine through Snapseed? If there's still an issue, maybe try with other third party camera applications that support RAW (e.g., A Better Camera), do they have the same problem?

It works fine in snapseed. Youmay close this ticket.
