digiscoping - As i know well digiscopers, the fundamental 'problem' of this technique is the absence of 'cleanliness' in the images taken with the long. With the term 'cleansing', however, many confuse blur with blur, and vice versa; especially because of the maxi-magnifications. These are two very different 'diseases', which as such require two well-differentiated 'medicines'. Let's see them in detail, starting from the diagnosis of 'evil', that is, recognizing when a photograph is blurred and / or when it is moved, or micro-moved.
A picture BLURRED on the subject is an image in which the focus (MAF) it did not go on the desired point. And, perhaps, he privileged a secondary detail in front of or behind the subject itself. The camera cannot know if we want to focus on the tree behind which the roe deer is hiding, or on the vegetation in the background. Sometimes it happens - a typical characteristic of the strong enlargements of Digiscoping - it can happen that in a frontal subject, which looks at us and is not in a 'postcard' position, the MAF goes (deliberately) on the muzzle and consequently blurs the tail or the side. rear.
The solution, in digiscoping, is, of course, one MAF corrected on the desired point.
In this case, it is necessary to differentiate according to the camera used. If we use a reflex with TLSAPO we still have to focus - by hand - on the long side, excluding the camera's Autofocus and working in M focusing (manual); if we use a instead MirrorLess, or one SmartPhone, we still have to do a manual and approximate MAF in the long run, but leaving the work of to the camera optimize the MAF on the desired point: where you touch the monitor, with the light finger (in touchscreen), both the exposure and the MAF go. It is not a true full autofocus, but everything works with a focus survey (or contrast) phase which facilitates the operation in a decisive way; In a more technical way, the phase detection 'reads' the correct focus on the second lens of the long: only in this way does the 'miracle' happen whereby a MAF that has not been manually optimized becomes perfect - and in the desired point - thanks to this type of AF automatic.
A picture MOVEinstead, it is an image in which everything that is included in the frame appears confused and not very clear. The movement or vibration at the point of recovery may appear insignificant, but over long distances it is a real earthquake. Or the photo is blurred, when the subject makes a sudden movement at the exact moment of the shot.
The solution, in digiscoping, is based on the maximum stability of the equipment.
To achieve this, you need not only a good tripod and a sturdy tripod head (not ball-type), but above all the balancing of the equipment. This is achieved - as we have seen - with the search for the center of gravity within which everything remains stable and effortless. The final result is that, after having engaged, it is no longer necessary to tighten the stops: the long one stabilizes - without passive play - in the exact desired point. This is the great advantage of the new balanced head PTH from Swarovski Optik, in synergy with the new sled balance BR
To "stop" the subject, hunters know very well how to use their voice and calls, but the ideal solution is remote release (even the silent one), forgetting the various VR and the high depth of field that have little influence in Digiscoping.
Just to highlight these fundamental differences between blurred photos and blurred photos, in our latest book - Stories of Digiscoping - we have attached a Technical Guide and each photo is accompanied by real metadata to highlight the technical parameters used. For reservations: [email protected]
