Αν και νομίζω αυτό το Ρώσικο φορουμ το έχουμε ξανα-αναφέρει,
το "ξαναδίνω" επειδή αλλάξαν αρκετά την εμφάνισή τους και δημοσιεύσανε παρουσίασή τους στο budgetlightforum, οπoυ αναλύουνε την μεθοδολογία τους

Ομολογώ οτι πρόκειται για μια εξαιρετική ομαδίκή προσπάθεια (κατι ανάλογο θα μπορούσε να κάνει ο ergotelis αν είχε αλλους 5-6 "ομοιδεάτες" στο Ηράκλειο...)
Shooting parameters for these tests.
As you can see there are four modes of view for flashlights called Road, Road 2, Wall and Body.
I used my Nikon Coolpix P5100 photo camera with tripod.
Road.
There are 2 targets on the road. They are 2-litre Fanta bottles with some water for preservation of stability during a wind. The distance to 1st target is 25m and to the 2nd is 75m. Some photos contains 3 targets (3rd=100m). All the flashlights are directed on the second target. The height of tripod with flashlights is 1m (like most of bicycle handlebars). The tripod with photo camera is situated a 1m before the flashlights tripod with the height of 1.45m (like your eyes when you riding).
Shooting parameters.
Focal length: 8mm (Focal length in 35 mm film: 35mm)
The angle you (camera) see is 90 degrees
Aperture size: F/3.0
ISO speed: ISO200
Exposure time: 1/2s, 2s, 8s
Road 2.
The same as Road, but the tripod with photo camera is situated a ~4m before the flashlights tripod to show you the light in near zone.
Wall.
The distance from photo camera to wall is 4m. The distance from flashlights to wall is 3m. The angle you (camera) see is 90 degrees, but for flashlights it is about 105 degrees.
Shooting parameters.
Focal length: 8mm (Focal length in 35 mm film: 35mm)
Aperture size: F/3.0
ISO speed: ISO200
Exposure time: 1/60s, 1/16s, 1/4s, 1s, 4s
Body.
This view mode contains the photos and specifications of flashlights. Many information will be there later.
