![]() About this time you might have a new problem, which is that you'll be really annoyed in situations where you can't plant your camera on a tripod. And eventually using the tripod will be so easy and so automatic that you won't even think about it. Practice, practice, practice: At first setting up and adjusting the tripod will be cumbersome, awkward, and annoying.If you were trying to make ev-bracketed shots, I bet the individual shots weren't exactly aligned with one another (even if the subject obligingly held still). If you are anything like me, the first time you tried to take a picture with your camera on a tripod, you decided that the results weren't worth the effort. One good thing about having purchased a Sony A7 is that now I have a long list of things to watch out for the next time I purchase a camera, which likely won't be a Sony even though in many ways I like my Sony A7 camera quite a lot. Only a limited number of the deliberately "firmware-crippled" features on the A7 have been "uncrippled" in the A7 MkII and MkIII, so many of the tips for the original A7 cameras also apply to newer A7 cameras.Įven if you don't have a Sony A7, you might find it interesting to peruse my list of complaints and associated links to articles about various shortcomings of the A7 line of cameras. This tutorial also has advice for dealing with the Sony A7's crippled firmware. If you've never done this before, or even if you have but your shots didn't line up, this article has step-by-step instructions for shooting from a tripod. This tutorial describes how to set up your camera and tripod for making ev-bracketed exposures. Fortunately, for reasonably static scenes shot raw from a tripod, Guillermo Lujik's "Zero Noise" technique produces clean shadows and intact highlights. Introduction Ev-bracketed exposures for "Zero Noise" photography Links to technical information about camera limitations imposed by the Sony A7 firmware (or some things to watch out for if you plan to buy a camera that will be used for making ev-bracketed shots or night/astrophotography).Introduction: Ev-bracketed exposures for "Zero Noise" photography, and a word about using tripods.: Results of post linked above were subsequently adjusted (from -2.10 EV) to a -1.794 EV (averaged Green channels) RAW-level under-exposure for E-M5 Spot metering case (EC=-1/3 EV). If EM5 owners use the EM5's in-camera (Spot) metering system, they will likely cause a situation where that potential Dynamic Range advantage will be transformed into a net disadvantage relative to the GH2 (by an approximately 0.90 EV degradation of SNR reducing the estimated 0.84 EV advantage in DR to an estimated net disadvantage of If EM5 owners use the EM5's in-camera (ESP, evaluative) metering system in order to determine Exposure when recording RAWs, they will likely cause a situation where virtually all of that potential Dynamic Range advantage will be negated (by an approximately 0.7 EV degradation of SNR reducing the estimated 0.84 EV advantage in DR to an estimated net advantage of ![]() If so, results of hypothetical calculations appearing below would be directly affected (which I think may be somewhat optimistic). Please note that the (actual, as specified by DxOMark) Dynamic Range of the EM5 (relative to GH2) may differ from the estimate made by The following statements apply to RAW recording, using EM5 in-camera metering with Exposure Comp=Zero (0) as compared to the GH2 recording "ETTR" (in previous posts on this forum) has estimated that base ISO=200 the Dynamic Range of the EM5 may be around 0.84 EV higher than that of the base ISO=160 Dynamic Range of the GH2. Averaged both Green channels in all calculations. We already know (from my example image posted) that the EM5 Spot metering mode can result in around -2.1 EV of (RAW-level-referenced) under-exposure. Thank you ! I'm glad that you used "ESP" Evaluative Metering (which meters at no less than 324 individual locations within the entire image-frame) - as evaluative metering (one would think) would clearly provide theĪmount of (RAW-level-referenced) under-exposure (as compared to Center Weighted or Spot metering modes). Finally, got (all) of the numbers right (corrections directly inserted)Įxcellent. ![]()
