R5 Noise, Dust, Scratches?

Hello,

I am an interior Design photographer and I just changed from the Mark IV to the R5. There is so much noise and some colorful dots all over my photos.

Greetings,

I pulled what data I could from your jpg photo. Are you shooting in RAW or .JPG typically?

What lens are you shooting with? Properties show 35mm and 26mm?

f14, 13 sec exposure. What kind of lighting was available?

In order for us to help, can you please post a RAW image of a problem photo. Use OneDrive, Dropbox, Google Drive etc. This will allow us to determine what the issue might be, exposure, camera settings, etc. We should be able to get everything from a RAW photo.

You will get dots at long shutter speed. Normally your raw converter will handle them.

In your case I would just take a dark frame. You enable Long Exposure Noise Reduction for that.

Greetings,

I see a bunch of hot pixels. These are a by-product of a 13 sec exposure. Reduce the shutter speed. Try f8 or f11 to keep an acceptable DOF. Use a tripod if you aren't steady. If you need to bump ISO don't exceed 800. You could also consider some off camera lighting.

Try shooting in Fv, Tv or Av to control one or more legs of exposure. You can shoot in "M" if you like, but not with a 13 sec, ISO 200, f14 indoors without better lighting.

I just asked Peter to take a look. He beat me to it.

Thanks Sir.

thank you for your response. I do use a tripod and use flash. This is just my base layer, and it just never happened with my mark iv. First time I have seen hot spots like this.

I just uploaded a couple more that are at faster shutter speed.

Thank you so much!

I will change that now and see if it makes images better at my job tomorrow. I appreciate your time!

I downloaded the raw file. Around 200 "bad pixels" due to the long exposure. The ones from your print screen are not removed in LR because they are in clusters. I think one strong pixel in the middle spills over to the other four due to the long exposure but I am far from an expert. You can try the sensor cleaning via menu method and see if that will remove the clusters.

The overall noise level is normal. Your print screen to the right.
