Several imported remarks to avoid
mistakes
when doing digital dermatoscopy.
1. At
first I verify that the dermatoscopy optics Heine delta 20 is
adjusted not for my eye, but after guideline which interlocks
accurate focal distance for digital camera Nicon Coolpix 4500 As
far as I know, other cameras are impossible to use, because only
Nicon Coolpix 4500 has outside object - lens screw mechanism
securing lineup conjunction to Heine Delta 20.
2. Before Photographing: there is recommended by Swedish
duster clean dermatoscopy optics, tangent slide and also camera
optics.
3. Screw extender on optics of camera.
4. Next step is at some time more difficult for beginner:
Extender connects camera by the aid of Bayonet catch. At that
time is dermatoscop and camera connected together. It does mean
for practice that the extender clutch arc press toward camera.
At the same time small bent connection locks will be opened. (Like
thumb nail jaws). Into thus prepared space insert, or rather
hardly push dermatoskop Heine delta 20 so, to at release
pressure on circle „jaws!" leapt behind hereto intended salient
guideline.

Shows
connection dermatoskop Heine delta 20 with digital
camera Nicon Coolpix 4500. Connection makes it
possible to extender which is to dermatoskop fixed
bayonet closure. Object - lens camera makes it
possible to screwed extender to dermatoskop.

5. That way makes safe line up
apparatus on dermatoskop.
6. Next step: we prepare camera into macro - regime.
In menu of motif programme we shift on “nosegay“(so called
regime close up). There is important to nosegay was also in
left upper corner of the monitor Nikon Coolpix 4500 and was
on yellowish color. (Do not do the same mistake which I did:
Several photographic specialists tried to help me and
centered camera for macro-mode photography but results at
that time were worse then ever. For instance instead of
focus camera on mother nevus occurred to sight on hair above
the nevus. Problem was resolved by interruption
