I'm totally new to this and I've wanted to get into Photography all my life. This is the best way to start I've ever found... I've learned TONS since I joined this site and so far I've only submitted to the 'Metal' challenge which isn't even finished yet! I hope you all don't mind if I share some cool things (at least I think they're cool) I've learned since I got here. I hope it helps others too...
FACT #1
What difference does ISO make to a digital pic?
Image noise / grain: Film grain is equivalent to image noise. At high ISO levels (film speed) the grain/noise becomes more apparent in the final image. Although film ISO levels can be lower than digital ISO levels (25 and 50 respectively), digital settings can be changed quickly according to requirements, whilst film must be physically replaced. Additionally, image noise reduction techniques can be used to remove noise from digital images, whilst film grain is fixed. From an artistic point of view, film grain and image noise may be desirable when creating a specific mood for an image. Modern digital cameras have comparable noise/grain at the same ISO as film cameras. Some digital cameras though, do exhibit a pattern in the digital noise which is not found on film.

I think the older folks (not to say all); myself included that enjoy grain in pictures. The younger folks may be use to digial art and computer manipulated without any grain almost sanitized art. Vector images all over the web and in ads add to this.

I agree that some noise is not a bad thing on some shots. And using grain to create a mood works when needed. But with a digital camera and film camera it comes down to did you pick the right ISO or Speed film respectfully for the shot. If you pick ISO 800 on a bright day with digital camera when ISO 200 would of given you the proper SS/A you made the wrong choice. The same can be said for film if you choose 800 speed film when a 400 speed film would of done the job. It's all about making the right decisions at the right time in both digital and film. As for the programs that take out noise in digital photography (NN or NI to name a few) can in some cases worsen the photograph instead of enhance it. The best is know the cameras limits (which I am still learning) and know what ISO/SS/A to use under different circumstance.

| I find that the noise produced from a digital camera does not have quite the same feel as noise from a film camera. Noise from a film camera just looks better. |

I think the reason for that is that the grain in digital cameras is more coloured, and in film the grain is sort of uniform, Making it look good instead of crappy.
Not sure though
But yeah... Film grain definately looks good if used in right places. Mostly in bw and sports photography |
