jonathan_hamilton Posted October 11, 2016 Share Posted October 11, 2016 <p>Many thanks indeed all - really appreciate your responses!<br> Take your point - auto exposure is bad - presume that auto exposure and auto ISO are 1 and the same thing. <br> Just to clarify (again, please excuse my ignorance) - is there a difference between auto exposure and TTL metering? <br> Also - just to follow-up on my questions above:<br> - Can anyone recommend a good remote flashgun arrangement that is ultra simple to use and appropriate for our setup please?<br> - Can anyone reccommend a really simple tabletop tripod other than the Gorillapod range please?<br> Many thanks again!</p> <p>Best regards,</p> <p>Jonathan</p> Link to comment Share on other sites More sharing options...
William Michael Posted October 11, 2016 Share Posted October 11, 2016 <blockquote> <p>"presume that auto exposure and auto ISO are 1 and the same thing."</p> </blockquote> <p>No. Not exactly. (see combined explanation below)</p> <p>*</p> <p> </p> <blockquote> <p>"is there a difference between auto exposure and TTL metering?"</p> </blockquote> <p>Yes. But the two have a relationship.</p> <p>Exposure is controlled by <strong>changing</strong> any one, or a combination of any of the three EXPOSURE PARAMETERS.<br /> The three EXPOSURE PARAMETERS are: APERTURE; SHUTTER SPEED: SENSITIVITY (aka "ISO").</p> <p>The TTL Meter will <strong>control</strong> the exposure (i.e. will change one or more exposure parameters automatically):<br /> 1. when the camera is set to <strong>any</strong> of the AUTOMATIC CAMERA MODES<br /> or<br /> 2. when the camera is set to <strong>any</strong> of the SEMI-AUTOMATIC CAMERA MODES<br /> or<br /> 3. when the camera is set to "Auto ISO"</p> <p>Examples of Automatic Modes are: "Full Auto" "Sports" "Portrait" "Scene" etc<br /> Examples of Semi-automatic Camera Modes are: Aperture Priority; Shutter Priority; Program</p> <p>The only Camera Mode(s) where the TTL Meter does <strong>not</strong> control the exposure are:<br /> a. Manual Mode <br /> b. Time Mode<br /> c. Bulb Mode</p> <p><strong>However</strong> some, but not all, cameras will <strong>allow "Auto ISO" to be engaged when the camera is in Manual Mode</strong>.<br /> If this is the situation then the TTL Meter will still control the exposure even when that camera is in Manual Mode.<br /> This could be relevant to the Nikon coolpix - I don't know for sure.</p> <p>I am not sure if any camera which has Time and or Bulb Modes available, will allow Auto ISO to be engaged when either of those camera modes are set.</p> <p>WW</p> Link to comment Share on other sites More sharing options...
