Digital noise and grainy sky??

Hello!

This photo has been rejected twice due to "Digital noise is visible. Grainy sky. Slightly unde-exposed."

Opinions please...

Sadly, I have to agree with the screener. It's a bit underexposed. You can just try Ctrl+shift+L in Photoshop and you will see the difference in terms of exposition and colours. Besides, jpeg compression is slightly visible in the sky, even without using the equalize mode. There is some digital noise only visible equalizing the image, but that's completely neglectable compared with the compression.

Hope it helps. Saludos.

if you want to avoid jpg compression, try "save for web" option (in Photoshop) with the highest quality (maximum and 100%) and make sure that all three options (progressive, optimized and embed color profile) are unselected.

Thanks for the reply! It's a little bit difficult for me because this is my "first time" here, but in the next days I'll try to improve this :)

Thank you Karol I'll also try out your option!

There are so many variables. Every monitor is different. Unless every screener is using the same monitor with the same settings every one will see something different and different to what we see when processing.

Processing on a 4K monitor is harder due to the extra pixel count. What looks soft on 1080 can be tack sharp on my monitor.

Very frustrating.
