I have a new modified Nikon d5600 and was out this past Saturday for the first time. In using Backyard Nikon's histogram and keeping in mind to keep the levels peak at 1/3 the red will be significantly separated from blue & green. That lead me to the question, should I still stay at 1/3 in histogram with blue and green and have red almost in middle, or would I ignore blue/green and focus on just red for histogram? I hope I am explaining this correctly, if not if anyone has a histogram they can share for a modified camera that would work too.
On a different topic, a while back I had read somewhere that for the Nikon the optimum ISO setting was 200, but of course I bookmarked it and now can't remember where I bookmarked (phone, tablet, work laptop, old work desktop, new work desktop...etc..etc.). Has anyone heard of this for Nikons? Trying to decide whether to look further into this, or just stick with ISO 800 which seems to be fine.
