Hi Everyone,

I hope you’re doing well,

I see my JPEG photos are sharp on both Lightroom and ON1 but unfortunately DNG photos are not. 
 

any idea how to make DNG photos are sharp same as JPEG ?

 

thanks

What software are you using for the DNG files?

Hi Gordon,

I use latest update for Adobe Lightroom

JPGs are sharpened in-camera, DNG conversions must be sharpened by the photographer during postprocessing (ON1); the sharpening level can be set in LR on export. Actually sharpening is quite a complicated subject, but best to master the basics first.

Sharpness can be a vague term.  Of course LR has sharpening tools, but flat looking RAW/DNG files (common with high dynamic range files out of camera) can be adjusted to give the impression of increased sharpness using a variety of tools.  These include contrast adjustments (using the tone curve or sliders),texture, dehaze, clarity, etc. One should learn the different ways these tools work, and their resulting effects.  JPEG files are adjusted by someone else.

That sounds like you need to study up a bit in postprocessing.

And there are dozens of other tutorials out there.

OK. Unfortunately there’s no real single, simple one click way to replicate all the things a camera has done to a jpeg. But basically it’s a mix of contrast, curves, clarity and sharpness sliders. A healthy dose of texture can help as well. Too much clarity and deglaze can look awful though.

Try this as a *starting* point.

Sharpness +40. Leave the other two sliders alone for now.

Contrast and exposure: Move those around to optimise the histogram. Just fixing your white and black point can make a difference.

Clarity +5 or so.

Curves. Grab the middle of the curve and push it up a bit. That’ll open the file up for you, which is a common thing for camera jpegs to do.

Now adjust texture to taste. And re adjust clarity, gently. Have a play with the detail slider in the sharpness module.

See how you go from there. Play. You can always hit reset. 

Ideally you shouldn’t be trying to replicate a jpeg. It should look better. Otherwise just use the jpeg. Personally I find most modern jpegs too orientated to huge contrast and sharpness so they work on small screens. Looks awful in print.
