Lightroom issue.

I am still learning editing software. I am still pretty new at photography itself. Started about 8 months ago, and learning a lot. Anyway. I have taken what I thought was some really good pictures this past weekend. They came out really good. In my opinion and others. I didn't have to do a lot of post processing in LR, just maybe some slight color corrections and a little sharpening. I always shoot in RAW. The problem that I have is when I export to JPEG I see a lot of noise/grain that I really don't see in LR itself. Is there maybe something I am doing wrong in the settings. I export at 300 resolution, matte/glossy paper, standard sharpen, about 90. Any help would be greatly appreciated.

LR works in Prophoto RGB while you export most likely in sRGB or aRGB but, in my case, that never caused noise. It can result in some color differences.

What might be possible is that it oversharpens. You can test it in LR; when you sharpen beyond a point, noise will start to appear. Check the sharpening settings it automatically uses while exporting and disable them to see if that has any effect on your problem.

Btw, what quality do you export the JPEG?

Good advice from J-see, when you do export check the % size, if I am keeping the picture I set it to 100%
If I put the picture on this website, then I set export on 40%, which gives you a file size of around 3mb.

Here's an example. I manually sharpened this to the max in LR. The first is export without sharpening, the second glossy paper high sharpening.

When you look at the wings it shows the additional sharpening triggered noise. I didn't process the background so you'll see little change there.

by quality you are talking about the resolution? 300 pixels if that is what you are referring to. I just export all of my pics for print quality. I get what your saying about the over sharpening. I am sharpening in the editing and I have the export sharpening also. So I will try different ways. Thanks for the input on this. I did get some really good ones without any noise. Possibly these pics may have been darker and I brought the exposure up on them too. I know that would give some noise too.

OK, here's the part of your post I'm confused with (in bold)...

I export at 300 resolution, matte/glossy paper, standard sharpen, about 90

I'm not sure why you're sharpening for a particular paper style (I don't even see that in my Export dialogue in LR), and I'm unclear what the 90 is.

With that said, the paper style thing is where I believe you may be getting most of this. In my experience, output sharpening for paper types expects that the image will only be used for printing and that there will be some level of run in the inks, so it will leave a bit of "room" to allow for that so the ink run doesn't reduce sharpness. The regular Lightroom Export function doesn't do this, so I'm assuming you're using something like Nik Sharpener Pro, in which case you want to sharpen for the screen and not paper (or do separate exports for each).

I don't like using default output sharpening and have sharpening turned off on all my export functions. I sharpen as the last step in the process, often using LR Unsharp Mask to do final sharpening, and then I bring the exported image into Photoshop (Elements would work as well) and apply some level of sharpening to the resized image. How much depends on the content of the photo. Blanket sharpening, which is what looks to be happening on your images, sharpens everything, including any noise that's there.

I was referring to the JPEG quality you export. It can be set from 0 to 100. I suppose you got it on max for print but when lower, that comes at a price too.

Thanks for the info on the sharpening. I left the "sharpen" box unchecked when exporting, because I do sharpen as last step when editing, and they came out really good. Appreciate it!!

In LR there really is little need to sharpen last.

Some shots I start with noise reduction and sharpening. It's what works best for anyone personal but I find it easiest to do sharpening before I change settings like contrast or exposures.
