    SJ7 yıldızımın 4K resimleri çok kötü. Neden olabilir?

    Küçük sensör ve zayıf ışık hassasiyeti nedeniyle.

    I still have not been able to get a quality picture. That's not the 4k photo.

    What metering mode did you use? Try the Center Weighted or the Spot metering instead of the Multi, if shooting portraits in such contrasty conditions.
    The photo by the mobile camera is obviously seriously overexposed.
    The SJCAM photo with zero EV correction is just about right (maybe slightly underexposed, but this is easily correctable in postprocessing), at least there is no serious loss of information, like on mobile cam's photo.

    Your mobile phone and the SJ7 camera have possibly rather similar camera sensors, so the potential should be similar. Mobile phones have generally much more processing power for initial postprocessing from the raw data to the jpg. SJCAM's jpg-s are generally of the softish side. I am not sure, but I think, that FW alghorithms should be blamed for this. SJCAM's Raw images are usually much better than it's jpg-s. Unfortunately SJCAM's Raw format is not recognized by most popular raw pocessing software. You must convert it with some command line utility like raw2dng or raw2nef first.

    Just did some exposure correction, resized the image (for proper comparision with the mobile cam's photo) and added slight unsharp mask to your sample images. If it was a raw file, then the result would be even better.
