Oh - you're serious?
I don't know how much experience you've had with Photoshop, but it seems that you've got the idea that it's some sort of magical cure-all. The brutal facts are that when it comes to photo-enhancing,
PS can only work with the data contained within the digital image - in other words, you can only bring out details if they're there in the first place. Apart from the blurred red/orange area (I'm guessing a fireplace) and some vague grey smudges there is no detail to enhance in these images - it's just black.
You could try the following technique which is called Contrast Masking and can usually bring out details in an underexposed image, although I'm 100% certain it won't fix these images:
- Duplicate your original image (Layer > Duplicate Layer)
- Desaturate the duplicate layer (Image > Adjustments > Desaturate)
- Invert the duplicate layer (Image > Adjustments > Invert)
- Change the Blending Mode of the duplicate layer to Soft Light
- Apply some Gaussian Blur to the duplicate layer (Filter > Blur > Gaussian Blur). Start with a small radius and gradually increase it until the detail starts to become clearer.
- If the shadows have become a little wishy-washy, add a Levels adjustment layer at the top of the stack (Layer > New Adjustment Layer > Levels) and boost the blacks.
