Re: Canon 50mm f1.4
Nat,
Second point first:
Check Chapter 4, Image Settings, subsection ISO Speed:
Enter the menu system, select Camera III and scroll down to "ISO Speed Setting" and hit the set button, you'll now see a nested menu including both "ISO Speed Range" for manual ISO range, and "Auto ISO Range" for automatic ISO range. Scroll to the desired one, and hit set. You'll now be presented with a screen showing two boxes labelled "Minimum" and "Maximum". Scroll to your desired box and hit set again, then use the up/down keys to select your chosen value, and finally hit set again to save it. Note that whilst the full ISO range (including extension if enabled) is available in manual ISO mode, only the standard ISO (100-25,600) is available in Auto ISO mode.
As for noise-reduction, the 6D offers a variety of techniques, none of which I use! One is to allow the camera to take a series of four images and composite them into a final JPEG file (so called multi-shot NR), this is of limited value unless you have a static subject, ambient lighting, and a tripod. A second option is for in-camera software noise-reduction, available in three levels, but this gives nothing which can't be achieved in post-production using Canon's DPP/ Adobe Lightroom, Adobe Photoshop, or any other decent software with a good deal more control. Additionally, high levels of NR can impact adversely on frame-rate as post-processing is applied at the time of the shot (this is particularly noticeable if you're shooting bracketed images where you can wait an age for the final shot to fire). A third option, Long-Exposure noise reduction, is only for images of 1second or longer and is akin to dark-frame subtraction used by astrophotographers and isn't of any real merit in everyday photography. This technique also doubles the length of each exposure, so a 5 second exposure can only be made every 10 seconds.
Think of Noise Reduction in the same way as you think of exposure, white balance, contrast, sharpness, or any other parameter - you know what you want/need whereas the camera will just apply a predefined algorithm to achieve a basic estimation of what it thinks might be appropriate. Using software in post-production gives you much more control over what you get!
