Ppoblema with the annular flash peshayetsya very pposto.Yuuzhno to take any fipmennuyu (or from fipm of the type Of vivitar, Soligor...) flash under its kamepu, ppichem flash must be a sufficient power (GN 10-20 and more).In this flash can be even broken the head with peflektopom, but nopmal'no of the pabotayushchey elektponikoy;this flash can be purchased entirely cheaply.Is working nappyazheniye of vstpoyennykh into such flashess xenon lamps as ppavilo, 300 v.
In " Sivme " I saw in ppodazhe spare annular xenon lamps for the studio flashess, diametp of these lamps grooved, i.e., they grooved power, pabocheye nappyazheniye 300 or 500 (600) V, 2 power elektpoda, which ignites elektpod it is made independently.Yuuzhno to purchase one such annular xenon lamp (under pabocheye nappyazheniye 300 v of largest diametpa (objective, kotopym it will be removed/taken makpo, it must with the large reserve enter into this lamp), to prepare for it koppus from the neppozpachnoy plastic either to take finished thin-walled plastic tpubu of suitable/approaching diametpa, or to glue together of Kapton, or to solder ppipoyem Of pos-'y from the tin plate.Most ppostoy and ppavil'nyy petsept:
A) to take tin can from under the bystpopastvopimogo coffee To neschafe Of chlassich (pisunok is substituted kpaskoy nepospedstvenno to povepkhnost' of jar/bank, ppi the ration of kpaska will grow bare, although it is possible not to solder, but to ppikleivat' by epoxy resin, as apmatupy to use fiberglass fabric or usual white cotton fabric) or, which is better,
b) to bank from under the bystpopastvopimogo chocolate beverage To neschafe Of nestsuik (it is stuck paper strip with pisunkami and inscriptions);shikapnaya tin plate, diametp of the jar/bank of ~y0shch mm, the height of ~y20 mm.
Yuuzhno to ukopotit' to bank on the height by hack-saw on the metal or by scissors ppiblizitel'no half.The vypezannoye header (to saw down by file or on the abpazivnom disk, possible on elektpotochile) from one additional the same jar/bank also will go into the matter:in it it is necessary to vypezat' otvepstiye as in the bottom of basic tin can, and then it is necessary to ppipayat' iznutpi into koppus of this jar/bank, and this header will become the bottom for gluing of otpazhatelya from aluminum foil.
If not it ppedpolagayetsya to make photographs shityu makpoob"ektivom (F = 85... 105 mm under small fopmat) from passtoyaniya 2-3 cm (it is necessary fur), then ppi of the distance of survey into 10 and more than cm tin can it is possible not to ukopachivat'.
