However if the file is already in 'compressed' format for example JPG/JPEG then all essential pixel data needed for processing already lost and you might not get much enhanced quality as good as bigger uncompressed file size of RAW file. *This processing tool will work on any image format. There so many RAW file format which includes IIQ (Phase One), 3FR (Hasselblad), DCR, K25, KDC (Kodak), CRW CR2 CR3 (Canon), ERF (Epson), MEF (Mamiya), MOS (Leaf), NEF NRW (Nikon), ORF (Olympus), PEF (Pentax), RW2 (Panasonic), ARW, SRF, SR2 (Sony) and also *.DNG (Digital Negative Images by Adobe) which is the one we're going discuss now since its output by DJI drone camera for our hobby. RAW photo files would look very dark and flat in color hence looks ugly at first sight when normal people see it. These file known as RAW DATA format because the file contain unprocessed and uncompressed data pixel of original files. Ideal photo to enhance have bigger file size contain more data per-pixel, store more information about color and ambient so it can be customized to the photographer liking and personality. Post processing is a technique to enhance original photo. For now i mainly use 'Raw Therapee version 5.8' to post processing all my Raw photos which we will discuss below. Right now the best option would be free to use tools, currently in my list the best two are RAW THERAPEE and DARKTABLE. Usually photography professional would use expensive tools such as ADOBE LIGHTROOM to process Raw photos however not everyone could afford to pay for such software. So if you wanted a good fantastic photos you'll need to 'enhanced' manually by tweaking the RAW photos like professional do. On the other hand JPG/JPEG format is already processed 'ready to use' image at default setting like you normally acquired from any standard camera.
The *.DNG extension file is an unprocessed photo with bigger uncompressed sized file which contain more information about the scene per-pixel which allow user to customized or enhanced the photo further. In your DJI drone you will mostly like find two photo format per-capture: *.DNG and *.JPG. To simplify the term RAW photo uncompress images that you find after captured a scene. This method is what photographer called 'post processing' work on RAW photo.
Any thoughts would be appreciated.For those who are curious how i manage to produce candy eye and vibrant looking aerial photographs i took using DJI MINI 2 drone i used ' Raw Therapee' program to enhanced the RAW photo (*.DNG files) then output to enhanced unique vivid colored photo on JPEG which you see a lot on my DJI MINI 2 aerial photo gallery recently. If, however, I wire it up so that I can measure that voltage while it is attached to the camera, it drops down to 2V, which I'm guessing is not sufficient to fire the flash. It does this even if the camera is off.Īt first, I thought the camera's hot shoe must be broken so that it was constantly in the "closed" position (thus completing the circuit for the flash), but my multi-meter says there there is not a complete circuit between the hotshoe components, and I have 4 other flashes of various brands (including another Andoer) that work just fine.Įven stranger, the flash circuit runs on 4.8V (i.e., if I take the flash off the camera, turn it on, then measure the voltage between the + and - terminal on its hot shoe connection, it reads 4.8V). If I pull it off and put it back on, it will again fire when it first makes contact, then not again. This flash has worked in the past, but now, if the flash is on, it automatically fires once when I first attach it to the cameras hot shoe, then it will not trigger again. I'm using an Andoer speedlight on my a6500. I've got some weird flash behavior that I don't understand.
