It confirms that I wish I still had my wife's old Canon DSLR to image my coins instead of my smartphone.  |

With old manual enlarger/duplication lenses you pretty much have to shoot in manual mode (focus and aperture, anyway). ISO is best left at 100 or 64 (the lowest setting for the camera). Then, manually adjust the shutter speed to avoid burning out the highlights. Use a mirrorless camera and make sure to use "silent shooting" / full electronic shutter.

Very nice Eyez.
Excellent and comprehensive chart. Very useful for beginners.
I think the only missing information is the sensor size. Why a cell phone camera is worst than a full frame camera?
The simple answer is the full frame camera gathers more light. So, in low light condition the noise will be lower than a cell phone camera for the same ISO-number.
It's not the only advantage of larger camera sensor, but it's one of them. But they are more expensive and bulky.

Very nice summary @Eyez !
Only thing I see to comment on, and it may have been this way in the original reference, is that the ISO vs Light is backwards in the leftmost image. The trend shows that smaller ISO is correlated with Less light, but indeed it should be that higher ISO is correlated with Less light. This is true from a couple perspectives:
When less light is available, a larger ISO (sensitivity) is selected to compensate
When a higher ISO is selected, less light (fewer photons) hits the sensor

just noticed that under iso should say more light needed at lower and less light needed for higher. |

I'm a little late to this party but the reason why a cell phone sensor is not as good as a "real" camera is more than how much light. And actually it's more than the sensor or ISO.
The lenses are just not as good. The phones will use sharpening and software to compensate but, starting with a lower grade image, to start with, does hurt some.
A bigger sensor with 12MP for example has larger pixels than a 12MP Phone sensor. Packing all those smaller pixels into the phone sensor, means your image isn't as sharp, when you make it the same size, as the one with larger pixels.
More depth of field, more dynamic range and in general a better image.
Yes it's true, the smaller sensor can't gather light as well as a larger sensor, but there are other important factors that matter as well.
Nice exposure triangle that's always a favorite as changing any one, will mean there will need to be changes in either one or both of the others.
You can't fool Mother Nature and that means the Physics of light in this case.

I do not know how and I'm trying to set my camera up no. I dont understand a thing on that chart. Iso should be 100, that I get. Setting this T3i up I dont.

@Minnimarine I go from iso 100-200 depending on color of coin most times I set to a low apature like f6-10 also depends on coin and lens that would be for my 50mm but if I use my 300mm then 11 to 12 shutter speed I'm pretty high because less blurr with any kind of motion.

@Eyez I'm using a Nikon 75mm with a helicoid. I'm starting to get it together. Grabbed some literature on it and then did some shots. Mostly trying to learn the definitions. Never did camera stuff. I'm learning. It seems 100 does pretty good. I will play around and see how it goes. Just picked up a 1905 Fredrick Baden 5 mark so I'm gonna take some shots and then move to smaller coins.
