I'm editing photos but the photographer was quite new and he took photos using Olympus OMD EM5II at 1/400, ISO 5000 and at f3.5 resulting in a underexposed noisy image. (The photos are raw.)
I tried searching youtube and googling on proper noise reduction techniques in Photoshop and Lightroom but it seems the photos are still dirty or look fake.
Can someone suggest a proper way to treat these photos? Or a workaround at least?
