This is a run-down of camera controls and options, without discussing flight controls.<br \/>\nDocumentation included with the Mavic Pro is minimal and help for the DJI Go app is non-existent.<\/p>\n<p>First of all, let&#8217;s point out the obvious. The Mavic Pro has unmatched portability; it folds to a size that can fit in a large coat pocket. The gimbal that stabilizes the camera is probably the smallest in the world.<\/p>\n<p>This drone can be flown using using the hand-held controller alone, or in conjunction wtih a smart-phone and the DJI Go app. You do need the Go app for access to numerous configurable options, but after configuring what you need, it is possible to fly with just the controller and no app. During flight, the Go app gives you a live video feed and camera exposure information, but you may not need to interact with the app except maybe to set the focus.<\/p>\n<p>Not all\u00a0available features shown here.\u00a0 These are just some features I wish to point out.<\/p>\n<h1>The Remote Controller<\/h1>\n<p>The hand-held controller includes quite a few camera controls, independent of any smartphone app.<\/p>\n<ul>\n<li>Photo trigger (shutter button)<\/li>\n<li>Start\/stop video recording<\/li>\n<li>Camera tilt<\/li>\n<li>Exposure compensation<\/li>\n<li>Custom button\u00a0left (e.g. center focus)<\/li>\n<li>Custom button\u00a0right (e.g. AE lock)<\/li>\n<li>5D button &#8211; up, down, left, right each has a different meaning that is configurable.<br \/>\n(For example, zoom in\/out.

The update can be applied with a simple touch; the download comes via your wi-fi, through the phone, down to the drone. The time to complete the upgrade was more than ten minutes and consumed about 18% of the drone battery charge.<\/p>\n<figure id=\"attachment_1042\" aria-describedby=\"caption-attachment-1042\" style=\"width: 640px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006.jpg\" rel=\"attachment wp-att-1042\"><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-1042\" src=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006-1024x767.jpg\" alt=\"Bearskin Neck\" width=\"640\" height=\"479\" srcset=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006-1024x767.jpg 1024w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006-340x255.jpg 340w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006-768x575.jpg 768w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006.jpg 1200w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/a><figcaption id=\"caption-attachment-1042\" class=\"wp-caption-text\">Bearskin Neck<\/figcaption><\/figure>\n<figure id=\"attachment_1041\" aria-describedby=\"caption-attachment-1041\" style=\"width: 1044px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006_enlarge200_compare.jpg\" rel=\"attachment wp-att-1041\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1041\" src=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006_enlarge200_compare.jpg\" alt=\"Compare JPEG to RAW\" width=\"1044\" height=\"524\" srcset=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006_enlarge200_compare.jpg 1044w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006_enlarge200_compare-340x171.jpg 340w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006_enlarge200_compare-768x385.jpg 768w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Rockp-0006_enlarge200_compare-1024x514.jpg 1024w\" sizes=\"auto, (max-width: 1044px) 100vw, 1044px\" \/><\/a><figcaption id=\"caption-attachment-1041\" class=\"wp-caption-text\">Compare JPEG to RAW<\/figcaption><\/figure>\n<h1>Photo\u00a0Quality<\/h1>\n<p>For photos, you can shoot RAW, JPEG, or RAW+JPEG. Of course, I recommend either RAW or RAW+JPEG.<\/p>\n<p>I shot the photo above (Bearskin Neck, Rockport MA) recently with the Mavic Pro set to record both JPEG and RAW.\u00a0 The second photo is a 200% crop from the center, comparing the original JPEG to\u00a0the RAW file processed as I normally would in Adobe Lightroom.\u00a0 Overall, the JPEG is good.\u00a0 I think it is a bit green, looking at the short stone wall.\u00a0 Signs on the buildings are not legible in either case, but the JPEG is slightly worse than RAW.<\/p>\n<p>With only a half dozen flights thus far, I have observed a couple specific image quality problems.\u00a0 For still photos, the very small image sensor is no match for a larger DSLR or MFT camera.\u00a0 I have read that the image sensor is Sony Exmore (<a href=\"https:\/\/en.wikipedia.org\/wiki\/Exmor\" target=\"_blank\">wikipedia.org\/wiki\/Exmor<\/a>), but I cannot confirm that. The maximum resolution is a respectable 12 megapixels, in 4&#215;3 aspect ratio (4000&#215;3000). You can choose to capture 16&#215;9 ratio, but that is a crop down to 9 megapixels (I personally tested that just now; that&#8217;s real, not a guess.).<\/p>\n<p>Photos\u00a0can exhibit some amount of digital image noise at just about any ISO. Images shot\u00a0during the low-light of\u00a0dusk, around ISO 1600, exhibit a high amount of chroma noise.\u00a0 Samples are shown here below.\u00a0 For stills, Adobe Lightroom has the best noise reduction I know. While the JPEG processing in the Mavic does a reasonably good job of smoothing large areas, there is loss of detail inside the bridge.\u00a0 The Topaz Denoise plugin for Adobe is similar.\u00a0 Processing via Lighroom&#8217;s built-in noise reduction allows better control and retains better detail inside the bridge.<\/p>\n<h1><a href=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Noise_compare_Mavicprod.jpg\" rel=\"attachment wp-att-1043\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-1043\" src=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Noise_compare_Mavicprod.jpg\" alt=\"Coping with low light\" width=\"1997\" height=\"1498\" srcset=\"https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Noise_compare_Mavicprod.jpg 1997w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Noise_compare_Mavicprod-340x255.jpg 340w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Noise_compare_Mavicprod-768x576.jpg 768w, https:\/\/www.kevindavisphoto.com\/blog\/wp-content\/uploads\/2017\/01\/Noise_compare_Mavicprod-1024x768.jpg 1024w\" sizes=\"auto, (max-width: 1997px) 100vw, 1997px\" \/><\/a><\/h1>\n<h1>Video Quality<\/h1>\n<p>In good light, the video quality is probably on par with a GoPro Hero 3 or 4.\u00a0 Moire problems may occur when scenery includes detailed patterns, but I have not tested this with different capture resolutions.\u00a0\u00a0As with still photos, low light and\u00a0high ISO\u00a0exhibits a high amount of chroma noise.\u00a0\u00a0 A product called Neat Video can do a good job of mitigating noise.<\/p>\n<p>The video clip of the snowy mill (at the beginning of this article) was\u00a0captured at 1080 without a problem.\u00a0 However, on a separate shoot, I did see a problem.\u00a0\u00a0 Several people contributing to on-line forums have reported that 1080 does have problems, including a &#8220;pastel effect&#8221; which seems an apt description of the problem I saw. People experiencing problems at 1080 also report that the problem does not occur at higher 2.7K or 4K resolution. I have switched to shooting 2.7K and subsequently downsample to 1080 in post processing. However, the higher resolution does not support a frame rate faster than 30 fps; and downsampling does require additional compute time.<\/p>\n<p>For video, I&#8217;ve been shooting the &#8220;None&#8221; color profile, modified with sharpness set to -1. Some pros are recommending two of the color profiles, DLOG (very flat) and ART (not as flat). Alternatively, some people have suggested color profile D-Cinelike and then customized to -2, -1, -1 (sharpness, contrast, saturation). All those suggestions create an intentionally flat result that\u00a0necessitates some post-processing.<\/p>\n<p>A clear plastic dome can optionally be used to protect the camera. Very first time I captured video with the Mavic Pro, I could see glare due to the plastic dome. Since then, I never fly with the dome attached. Potentially, I might use it if there some risk of water or dust in the air, for example, flying near a waterfall.<\/p>\n<p>&nbsp;<\/p>\n<h1>Pre-flight<\/h1>\n<p>Each time you fly, here&#8217;s the basic pre-flight steps:<\/p>\n<p>1) Unfold the propeller arms and propellers<br \/>\n(Obviously, attach any propellers that you detached for transport\/storage.)<\/p>\n<p>2) Remove the camera gimbal clip<\/p>\n<p>3) Optionally, connect your smart-phone to the hand-held controller<\/p>\n<p>4) Turn on the controller and\u00a0start the DJI Go app<\/p>\n<p>5) Turn the antennae upwards, which is typically a 45-degree angle<\/p>\n<p>6) Turn on the drone<\/p>\n<p>7) To connect your phone with the drone, touch the &#8220;Camera&#8221; button on the DJI Go app<\/p>\n<p>8) Check the aircraft status information, including available battery charge<\/p>\n<p>9) If this is a different location than previous flight, calibrate the compass<\/p>\n<p>10) Obviously, check your environment for obstacles or hazzards.<br \/>\nMake sure you are not in restricted airspace.<\/p>\n<p>&nbsp;<\/p>\n<p>DJI includes a plastic clip to secure the camera gimbal when not in use. Always remove this clip BEFORE turning on the drone. If you fail to do so, the app warns of gimbal overload.<\/p>\n<p>Initially, the Go app will display the &#8220;Aircraft Status&#8221;.
