You mentioned shooting at 80 ISO indoors, and this might be your problem. If you are trying to keep the ISO low and taking dark pictures, and you then need to increase the exposure, this can often bring up noise. Especially on a lower-end camera, if you don't expose it properly, even when shooting RAW, you can have an issue. It's best to expose properly even if you need to bump up the ISO to do it, rather than playing with the exposure in LR.

Moving the noise slider to 70 or 90 seems excessive. It will make even a very sharp photo soft.

I'm not familiar with your camera but if you find you are bumping up the exposure, try shooting at a higher ISO so that you don't need to increase exposure. I know from experience that with my full frame Nikon D700 I have more leeway than with my Olympus OMD E-1 if I shoot a photo that is too dark, although when properly exposed I get amazing noise-free photos from both cameras. I've shot at ISO 1600 with the Oly and had amazing results when they are properly exposed, even though it has a small sensor.

Good luck!

Hello Wordplanet, no I don't need to increase exposure in Lightroom. I use a tripod and my shutterspeed is low. As I said beforee, I get that noise inn bright daylight. I will check the Jpeg later. I thought for �800 I would get a proper camera. I didn't think about the small sensor inside. More about if I can lift and hold that camera. 

No, I edited my sharp peanut cookies yesterday. They were shot indeed in a darker place . I normally don't take photos in my kitchen. When I reached  70 I stopped in horror but there was still noise. Noise was gone on setting 90. My cookies looked softer than soft. I checked the RAW file and they were sharp. I threw the photos in the bin. With Affinity and in outside sun I still have to go up to 50. DT accepts them. SS wants more noise removed. The accepted the sky after I removed more noise. This noise maker is no fun. Is there a lightweight camera that doesn't make noise. By the way, Serge, who owns the �2500 Sony A7R needs to pull the noise removal slider in LR to 40. That is a full frame shocking expensive camera. Price without lense. I do have the Topaz Collection. I could try removing noise with DeNoise instead of in LR.

I just read the following about this camera. Maybe it's not meant for commercial photography. Not when they want that much noise removed. Here part of the review:
Depending upon how you plan to use them, the photos can be considered acceptable through the top of its sensitivity range, ISO 12800, although you probably don't want use those shots at 100 percent. The processing and noise reduction are okay, though even at ISO 400 you can start to see some mushy edges and the not-terribly-smooth out-of-focus areas that typify small-sensor cameras. Nevertheless, in-focus areas still look good up through ISO 1600.

I just edited the RAW file completely and despite setting the sharpening slider to 35 the image is soft and not sharp. The Jpeg is still super sharp. I have not used the sharpening slider. I didn't use the Clarity slider because I didn't want to sharpen the sky. Well, the Jpeg is great and the RAW is bad. However, yesterday's image was edited using Affinity Photo. It must be the heavy noise removal that ruins the images. Maybe the camera removes already some noise when processing it into a Jpeg.

If you shoot similar images and the jpeg looks better than the raw file (after processing!), then that simply means that the jpeg engine in the camera is better than your post-processing skills.

That the unprocessed raw looks worse than the jpeg out of camera (more noise, softer) is no surprise, that's just what raw files are - you need to process them to look good. The advantage with raw is (only) that you have a lot more influence on how to process them instead of relying on the in-camera software.

Now you know what to work at.

I just have edited the RAW. The RAW still looks worse. It gets soft when I have to set the noise removal slider so high to remove noise. I can't just leave all that noise. It will simply get rejected. I also edited again, this time using Clarity and sharpening slider. No difference. Still soft. If I don't set the noise removal so high, I still have noise. I think I will shoot in Jpeg from now on.

Thank you Fudio, I only bought Lightroom about 3 weeks ago. I watched lots of tutorials. With Affinity I use Clarity and set sharpening to amount: 15. I bought the Topaz collection about one month ago to help with my art images. With them I am more brutal. I just don't know how much to do on a photo for microstock. I read to leave the sharpening to the customers and the colour......But why shoot in Raw for microstock when Jpeg's are so great and so little work? For art that's different. The Topaz collection is a lot to learn. I did well when I had my Windows laptop and used Corel AfterShot Pro 2 and Corel PaintShop Pro. Affinity Photo I bought about 2 months ago when I got a MAC. I had a 100% acceptance rate on DT using my Windows Computer. Oh, yes, DXO is great for noise removal. I had to decide between buying Lightroom and DXO Elite. Since I have problems with my arms I might try shooting in Jpeg for microstock.

Hello Michael, I just starting watching your Lightroom tutorials. I do have Lightroom in English, aber ich werde das schon verstehen. 
Thank you very much for the link. Much appreciated. Thank you to all of you for all your help and support.

Fotolia sold one of my photos today. A cat photo. A cute one. I got 1.60 credits for it. It was bought in size L. I don't understand that. A travel photo was bought in XL and I got 0.25 credits for it. Why the difference? Why did I get more for the L than the XL ?

I'm not on Fotolia, but it took me about ten seconds to find:

Thank you ShadySue. I just read: For each sale, contributors are paid a commission in credits (1 credit = �0.75).
Why did I get 0.25 for my first sale which was in XL size?
