Has some nice graphs showing noise at different ISO settings. I have never shot at ISO The noise is so negligable at that the doubling of shutter speed is far more valuable to me. Worrying about noise will make you neurotic and cost you a lot of good shots. I'm at ISO more than any other and try to keep it there, but is also very good and the increase in noise is hardly noticeable over But if it's a matter of getting the shot; crank up ISO.
Noise Ninja does a fantastic job! Noise is nothing to get excited about It's still better than the film grain at any day of the week! As DN says, noise ninja cleans it right up is I miss on the exposure. If you have to boost your shadows you'll make the noise more apparent So best to bracket if in doubt. I had no idea digital cameras had a native ISO. That's very good information to have. AAMOF, it should reduce the noise even further. What it will do, though, is reduce the dynamic range of the sensor by approximately however many stops the ISO is decreased by.
Of course, I could be wrong, too. Photographers working in analogue should select the photosensitivity of their film in advance, before starting a project, since it is tricky to change films while working. With digital cameras , there are no chemical changes to the sensor and the ISO sensitivity can be set differently for each picture. When light hits the sensor semiconductor chip , an electrical charge proportional to the amount of light is released and stored. This is called the photoelectric effect electrons are emitted by a semiconductor exposed to light.
At the end of the exposure process this voltage electrical charge is read by the sensor and processed. The camera sensor itself always maintains the same degree of sensitivity; only the level of amplification changes.
Depending on lighting conditions, the ISO setting will either be selected automatically by the camera or can be changed manually. We should be exploring new ways of presenting images not hankering for the past. Edit: 5 hours later. I still have not been able to find out the native ISO of the D but what is worse I now have no idea whether it's a Toshiba or Sony chip that is fitted. There is no definitive answer so far as I can see.
Plenty of opinions based upon someone's Uncle's next-door-neighbour's pen-friend's cat's suggested rumour source but nothing easily and simply found.
Will ask Nikon directly. Information about the native ISO from our cameras is confidential as well as the manufacturer of the sensor. If you have other questions, feel free to contact us a again.
So I've asked them why it is confidential. As I cannot see how that information would hurt the company any way but especially as the D is an obsolete camera now.
Now in digital camera it's the sensibility to light of the sensor. It is not achieved the same way but it have the same role in the exposure triangle. That's why they call it ISO. As Joe has mentioned that is the range of selectable ISOs listed in the camera which can be chosen.
It could be that is the native ISO and everything above that an amplification but the man in the video suggested that the signal can both be amplified and 'throttled' which implies that the native might be for example It is that figure which I am interested in.
With digital you amplify the signal to vary ISO - with a film camera you change the film. With digital it is the sensor that has a native ISO essentially 'the camera' as you cannot change a sensor afaik. Thank you sir. I do understand. Have been shooting film for about 60 years now. Digital is was a bit new to me and had to acquaint myself with its verbage.
Thank you. Timothy, it wasn't you, you cannot 'vote' on your own posts for obvious reasons as the buttons are greyed out. It might be somebody hit the wrong button or made a mistake or just failed to see the humour in your comment.
I saw a lovely one the other day and was sorely tempted but the cost of film and developing etc is so high now that it really was not a practical proposition. Yes thank you. I was replying to Jon Kellett.
I love Pentax. Had a K to train for camera repair decades ago. Enjoy yoyr day and lock up, if you're isolating yourself. Sorry for the confusion, I was commenting about the downvote you got from Joe Dredd - Totally unfair of him. You know I miss the excitement of seeing the prints for the first time.
I love the smell of the prints, of the negs, of the photo lab. I just don't miss the cost and low res. Yes i understand what you mean. I mostly shoot slides for agencies and myself, but do shoot print film as well. I like waiting for 'Christmas' to arrive after I've turned in the slides for developing.
Have a safe day. I'm a bit lost. I thought the native ISO was a combo of the sensor sensitivity and the parameters of the amplifier in camera. The sensor is what it is but the engineers design a amplifier that runs for arguments sake from ISO to ISO and anything above or below that ISO rating is a digital manipulation in camera not analog.
Any one care to correct me if possible. That is essentally what the man said as I understood it. Each sensor has a native ISO. Some sensors have 2 more? And he amplification starts from a second level a fresh rather than being exponential. To go further, watch this excellent video produced by LensProToGo :. Remember Me. Lost your password?
