Nikon D750 Sharpening

[Bene Placito]

I've been using a D750 for a week now and have discovered that to get sharp images, I'm having to bump up the number I usually use in Photoshop. Currently if I use Amount 80, Radius .7, Detail 35 and Masking 45, I'm getting very good images.

This is way higher than I use with the D810. Perhaps it's something to do with the fact the D750 has an AA filter?

Anyone else noticed the same or is anyone else using the same sharpening amounts?

With the latest D750 Firmware update I'm finding a lot of my shots are now super sharp with the 70-200 2.8. They use to be a rad soft I thought.

I think the VR fix and maybe focus point fix helped me.

Have you tried that?

When I had a D750, my pictures were sharp as they are with my D810 right out of the camera. Rarely do I need to add any additional sharpening. are you checking your setting and F stop in particular? As you may already know, I small f number is going to yield a very small in focus area.

Thank you for your response.

I have just updated the firmware to the latest version and will take a few shots this afternoon.

I'm not complaining about the camera or the lenses, it is just that I seem to need to add more sharpening to the RAW files than I do using the D810.

Lenses used so far - Nikkor 50mm f1.4, Nikkor 24-70mm f2.8 VR and Sigma 24-105mm f4 Art.

i will say that compared to the D600 the D750 does not seem as sharp, dont know why. But i increased the in camera sharpening and that gives better results. Its plenty sharp though, but in a natural way, with this camera i am not getting that fake digital look that you often see online

 

[Hans vdC]

went to nikon from canon and sony mirrorless about a year ago (well sold canon and use it next to sony). raw definitely needs more sharpening on the d750.

I just decided to use the settings you suggested for sharpening...really good!

I've been playing around with various settings and comparing with the D810 and these settings seem to be a very good starting point for sharpening.

The D750 images sharpened as I've suggested, don't look any different from the images from the D810. I'm very pleased with the D750 output and performance.

The level of capture sharpening needed for an image to appear 'sharp' seems to be very subjective. My default settings on the D750 in Camera Raw or Lightroom are Amount 35, Radius 1.0, Detail 35, Masking 0.

Using these settings I find the D750 images have slightly higher acuity than my former D600's images. I've seen referenced somewhere (can't remember where) that the D750 has a less aggressive AA filter than the D6x0 series. However it would still seem less sharp than the D810 which of course has no AA filter at all.

The key thing is to not be worried about cranking up the capture sharpening if it's necessary. There is a difference between resolution (cannot be improved with sharpening) and acutance (improved by sharpening). An image can have good resolution but low acutance can make it appear soft to the human eye. Appropriate sharpening resolves that problem.

I have found if I don't use masking of at least 35, the sky in every shot has a significant amount of weird noise in it. I do the old "alt" key whilst dragging the masking slider across until the speckles disappear from the sky.

I haven't printed large from the D750 yet but D810 shots process like I just mentioned have been printed at 60 inches wide and look terrific. They don't look so terrific without masking.

Yes, AA filters always blur the image. They are low-pass filters and blur shorter wavelengths.

The D800E and D810 images don't need as much sharpening, but they occasionally need some aliasing help.

Yes, I usually end up adding masking if the shot has any areas of smooth tone such as you get in a sky. The settings I described in my post are just the starting point, a default that works OK for most shots. I apply this as an import preset, then I adjust further as I edit each select.

I will adjust the radius "by eye" until the image looks good without to many halos. Depending on the lens and aperture, wider radius helps remove some of the lens blur. With a very sharp lens (85 f1.8), smaller radius would be better - less than 1. For a telephoto, maybe 1.5 .

I agree with what you say. A fellow photog told me years ago, "If you can see the sharpening, it's too much."

My shooting with the D750 has been almost exclusively with the new 24-70 f2.8 which needs a wee bit more sharpening than the original one did. It is an overall sharper lens than the original though with much better and even sharpness across the frame.

dampens, not blur

It pours water on the shorter wavelengths?

Attenuates maybe ?

But I don't see any problem with using the word blur.

Because it does not "blur shorter wavelengths". It lowers their contributions.

I understand your point. I think "attenuates" is a perfect choice. Thanks.

What values you guys use for the D810+ Nikon 24-70VR? I’m not sure about default values in the “Detail” tab (see picture attached).

Thanks!
