- Oppose - overly compressed/JPEG artifacts, needs a higher quality export from RAW. MER-C 16:39, 23 January 2019 (UTC)
- Could you please explain what the artifacts are so I can correct them? Also, could you explain what you mean by a higher quality export from RAW so I can possibly address that as well? Thank you. PhotoDoc — Preceding unsigned comment added by 198.89.66.135 (talk) 21:00, 23 January 2019 (UTC)
- You need to go back to the original file you downloaded off the camera (hopefully in raw image format) and enter a higher quality setting when you save it as a JPEG. You should aim for a file size of about 3-4 MB or a quality setting of about 97 instead of the <~ 80 you put in. The blocky noise in the background at full resolution (the JPEG artifacts) should disappear. MER-C 21:35, 23 January 2019 (UTC)
- Thank you for clarifying. Went back to the original raw image and saved it as a higher resolution JPEG. Replaced image, current file size is 6.85 MB. Thank you. PhotoDoc —Preceding undated comment added 22:45, 23 January 2019 (UTC)
- The artifacting is gone, but it has unmasked image noise due to your choice of ISO sensitivity. You've got a fairly old entry-level DSLR, which doesn't perform too well at higher ISO settings. A noise correction will help, but I don't know whether it will be enough. For future reference, a shutter speed of 1/800s at ISO 200 and the same f-number yields effectively the same brightness and sharpness but with much less noise. MER-C 13:18, 24 January 2019 (UTC)
