How to use qDslrDashboard and Auto Holy Grail - Gunther - 2016-08-03 How to setup a shot with Auto Holy Grail:
RE: How to use qDslrDashboard and Auto Holy Grail - RvDam - 2016-08-12 Default qDSLRDesboard wil check every 3 image for the correct exposure. Have you experimented with longer intervals. For example, with 5 images? RE: How to use qDslrDashboard and Auto Holy Grail - Gunther - 2016-08-12 You can change it in the settings, but I always leave it on the default value, I see no reason to change it. If you change it however, you shouldn't set a lower value to prevent that the adjustments happen too close to each other. RE: How to use qDslrDashboard and Auto Holy Grail - haze2 - 2016-08-13 I'm shooting a Nikon D750 with the Dynamic Perception Stage One Slider and NMX controller for a multi-axis Milky Way time-lapse. Will the NMX controller work ok as my intervalometer? Frank RE: How to use qDslrDashboard and Auto Holy Grail - Gunther - 2016-08-13 Yes sure. Sent mobile with Tapatalk. RE: How to use qDslrDashboard and Auto Holy Grail - DeanAZ - 2016-08-13 Spot on, Gunther. I wish I had read this several months ago but this is almost exactly what I came up with based on trial and error. I shoot with a D7000 and a D7100 and use the MX2 for the intervalometer even if I don't move the camera on my sliders. To save my camera battery I also turn off image review and power down the LCD. I also direct the jpgs to the second SD card to make it easier to discard them after shooting. RE: How to use qDslrDashboard and Auto Holy Grail - Gunther - 2016-08-13 You know that the LRTimelapse importer has an option to ignore the jpg when bringing the sequences to your harddrive?

RE: How to use qDslrDashboard and Auto Holy Grail - adphoto - 2016-08-14 Last evening I tried the "Auto Holy Grail" with "Sunset" but when the scene become dark the APP changed the ISO / Shutter Time values so that the recorded images were very very bright. Was this happening because the APP get as reference the histogram of the first image then try to change ISO/Shutter Time so that every following image match the histogram of the reference? If not, what is the algorithm behind modification of ISO/Shutter Time? Thanks, RE: How to use qDslrDashboard and Auto Holy Grail - Gunther - 2016-08-14 It's as good as impossible for an algorithm to predict the luminance progression (and rather unnecessary to), that's why we do that in post when editing the keyframes. While shooting you just have to take care to stay inside the dynamic range of your sensor. This is why you can and should from time to time change the reference during shooting (see last bullet point in the faq above). If you feel that the images get too bright, just decrease the reference value. RE: How to use qDslrDashboard and Auto Holy Grail - adphoto - 2016-08-14 Thank you for the explanation. Please help me to understand the logic of "Set Reference" button: - If I press "-" it set the camera to make the next image "darker", meaning reducing Shutter Time or lower ISO - If I press "+" it set the camera to make the next image "brighter", meaning increasing Shutter Time or increase ISO Is my understanding correct?
