Hi Guys,

Just a quick overall question on battling Jpeg compression. The photo attached is from a misty day, this is why I wanted to take photos from this angle to get the misty sky. However the misty sky has Jpeg compression, how can I combat this? Would a higher quality camera work or is it simply the conditions of the photo.

Thanks

Andrew

The colours are not showing in the image I have posted for some reason, maybe due to downloading the image and not sourcing straight from my hard drive as I am away from my laptop.

Hello!

I think ist due to the hazy sky and youre sharpening process! Maybe try to blur the areas, that have jpg compression. And as Catalin81 already said, the Image has low Saturation (almost no Colors).

I Added a Image how about the Colors should look, please ingore all the mess in the sky ;)

Realy the sky is abased by jpeg compresion. If you choose in Photoshop Image,Adjustement, Equalize it is demonstrated without doubts.

How to avoid it ? Imho shooting in RAW, postprocessing TIFF , resizing with bicubic ( best for smooth gradients ) function and saving for web with max quality should help , minimaly is jpeg compresion under better contol than whe shooting directly ( in camera) to jpeg.

Generaly speaking jpeg compresion is always giving minimal volume of data to monotone areas and thats why is sky ( or other monotone areas) " pixelized" in extreme conditions.

Thank you Igor!

I have already done all of these so I will take it that it is just the misty skies adding to this.

Sometimes it just cant be helped and there is nothing you can do. I have similar shots that I just cant do anything with...move on to the next image and scrap this one ;)
