1 Proterozoic: this eon refers to the time from the lower Cambrian boundary, 541.0 Â± 1.0 Ma, back through 2500 Ma. 2  As originally used, it was a synonym for Precambrian and hence included everything prior to the Cambrian boundary.
Canon's 50-megapixel EOS 5DS is the highest-resolution full-frame DSLR ever. If you thought the megapixel wars were over, think again: Canon's latest DSLRs cram just over 50 of them into a full-frame sensor.
The increased capacity of larger pixels also means that they can contain more light before they are full â and a full pixel is essentially a blown highlight. When this happens on a densely populated sensor, itâs easy for the charge from one pixel to overflow to neighbouring sites, which is known as blooming.
