I'm about to buy a 1dx mk2 and I have a question.
What max ISO do owners feel comfortable with?
I'm taking a trip to the Mach Loop next week and really don't want to go home with a couple of thousand newspaper print quality images.
I understand settings will vary depending on circumstance but I can't believe 490k could be considered useable.
I started reading all the comments on this thread to find an answer but there are so many pages I gave up.
My thanks in advance.
Here are two 51,600 ISO 1DXii images
- the first one is a rubbery looking in-camera jpeg with medium NR and the 2nd is a RAW file that I spent 3 minutes on (notice the detail difference)
- i mention this fact because if you are willing to spend the time with an individual raw file, and NOT turn the jpeg file to mush by throwing FULL automatic jpeg NR at it, you can absolutely do one full stop better than Canon's jpeg engine
My personal answer in terms of acceptable ISO is:
- lower is always better but no one paying your bill will ever notice the difference ISO 100 and 400
- Experts notice the difference between 400 and 800
- knowledgeable pixel peepers will pick up the differences between 800 vs 3200 everytime but with good NR, your mother won't have any idea
- given the rule of doublings, or halvings of light, 3200 iso, no matter the sensor or the jpeg / post processing magic, is the last ISO where the color is sort of holding it together - but if you asked a Commercial Photog doing $50k work for a magazine they would puke at the suggestion that 3200 iso is useable - but your mother will never say that a 3200 ISO image isn't excellent
My auto ISO answer is 25,600 for most things but 51,200 if you are willing to spend the time in PP. If you really want to know my real answer, I never like to go above 3200 ISO because the colour is never the same.
