    WTTYWRITE A BOOK ABOUTIT?There is no ideal att-round camera;every camera s theresult of a compromisebetween performanceand price-

    whether you measure he pr ice in terms of speed,con-venience, r s imply pounds, hi l l ings nd pence. The boxcamera, he miniature, the reflex, and the stand camera,offer certain characteristic dvantages ccompaniedn eachcase by equally characteristicdisadvantages.In the PurmaSpecial e have he resultof a new type ofcompromise-a compromise between the desire to takegood photographsand a strong reluctance o go to anytrouble over them. lt ls, in fact, a lazy man's cahera, andthosewho condemn t on that ground gnore he tremend-ouscontributlon o humanprogressmadeby menwho weretoo lazy o be happ)rdoing things the hard way.The shutter speed s the only thing about the PurmaSpecialwhich can be adjusted,and even his operationcallsfor neither knobs nor levers, t is regulatedsimply by themannerof holding he camera. Everythingelse s eitherdone for you or it cannot be done at all. The lens has notonly a fixed focus,but a fixed aperture,and t is neither lucknor coincidencehat this combinationof distanceand stopls the very one which the good photographeruses moston four days out of five. The good photographerarrivesat this setting after some deliberation,consultationof anexposure meter or guide, and finally, two separateadjust-mentsof focusand aperture. This cameradelivers t ready-made.In many ways the Purma Special s the ideal camera ornovices ut its utter simplicity s responsibleor its frequentappearance n more exalted company.

Thisallows^a much.simpler classificationof fi lm sp'eeds.All fi lms below 24' Sch. (European) are too slow to be of much useto the Purmawhich cannot give dn eiposure longer than l/25 sec. The

    remaining speedscan be grouped int i r three: Low speed'(24oSch. to26"-S:L.) :Middle speed (27'Sch. to29o Sch.)and High speid (30. Sch.to 32oSch.)., ,The Low speed films are roughly half as fast as the Middle speed films(they the.refore.require twice the exposure) and the High sieed filmsare roughly tqlcg as fast as the Middle speed films (t-hey'thereforerequire only half the exposure).Latitude- The fi lm is.gpable of. esponding tola very wide range of light varues,from very dull to very bright-a much widdr range thin is found in theaveragesubject. lt isthus generally possible o stray from the so-calledcorrect exposure-and stil l be within the range of the fi lm's power toreproduce the l ight and shade of the subject. Thanks to th i ; la t i tudethe three shutterspeeds of the Purmawil i usual ly nclude one which isnear enough tg the correct exposure for practi-calpurposes. As thelatitude of the fi lm extends more-above han below thecoirect exposure,it is a safe rule, when the correct exposure lies between two Shutterspeeds, o choose the slower,-i.., t6 over-expose.8

    GrainThe black parts of the negative are formed of microscopic grains ofmetallic silver. These grains are too small to show in contact prints orsmall enlargements, but in big enlargements they can appear as ageneral spottiness which breaks up the definition of sharp lines anddestroys detail.The size of the grain usually varies with the specd of the fi lm. Lowspeed films have a relatively fine grain and glve the best enlargements.High speed films have a much coarser grain which shows more whenenlarged to the same degree.Some developers tend to leave he negativewith a coansergrain thanothers. Ordinary developers, suitable for roll fi lms larger than V.P.,are unsatisfactory for negatives as small as those of the Purma. Forall ordinary sizes of enlargement any of the proprietary fine graindeveloperswi l l do, but for minimum grain size, one of the u l tra f inegrain formulae must be used. The disadvantage f the latter is that theymay require up to three times as much exposure, which practically

    rules them out for Purma photography.When to Use WhichThe best i lm for eveq/dayuse s undoubtedly he Middlespeed panchromatic ind. This is not too slow for brightwinter days and not too fast for strong summer lighting.It hasa grainsize ine enough or all normalenlargement ndits tone renderingof natural colours s the best possible.Its balanced colour sensitivity makes it excellent forportraiture, particularlyof childrenandyoungwomenwhosecomplexionswould be reproduced n unduly dark tones by,orthochromatic ilm.

    The Effect of Film Speed.. fo produce he samedegreeof blackening f the negative,light must act for a longer time on a slower fi lm than on afaster one-i.e., the slower fi lm needsa longer exposureunder the same ight ing condit ions.^.As grouped.for the Purma user (see p. lB) Low speedf i lms need wice as much exposureas Miaatd speedhlmsand four t imes as muchas High speed i lms.The Strengrthof the light

    The strength of daylight varies according o the monthand the t ime of d^y. In-winter he l ight is-weaker han insummer;at mid-day t is stronger hin in the morning orevening.. The photographic alueof the sunl ightalsodepends ponhow.much of it gets through the clouls and haze. lf thereare heavy.clouds.obscuringhe sun, he l ight at mid-day nJuly can be weaker than on a clear Decembermorning.

    So the weather must be taken Into account In decidingwhat exposure o give.Bear idg n mind-the imited rangeof the Purmashutter,only three very broad types of l ighting need be consideredat any t ime of year:-Bright: un hiningn a clear kY.Goid: Normal fine weather with thg sun iust strong enough toDroduce faint ly visib le shadows.' Dult:-Sky dompletely covered with cloud through which the suncannot be seen.Good light needs hree times as much exPosureas Brightl ight. Dul l l ight needs hree to six t imes as muchexPosureas Good light.

    The Type of SubjectA photograph s madeby light reflected from the sub.iect.The 'l ight ieflected from'a whitewashed cottage will actupon t-he ilm much more strongly than the weaker reflec-tibn from a dark-timberedbarn,-aithoughhe samedaylightmay be i l luminat lng oth sublects qual ly .The barn, here-for'e,will needa longerexposlre than he cottage.Similarly,an open landscape r seascape ill need a much shofterexposure han one with heavy masses f bui ldings, rees,or groups of people in it, particularly if they form theinterestof the picture.Here again,dhreegroups are sufiicient or the simplif iedtechniqueof Purma photography:-Light:Open andscapesithout important oreground.Snowscenes.Normoli Open landscapes ith important foreground figures orobjects.

    Why a Lrens HoodThe lenshood prevents unwanted ight from fatllngonthefront of the lens, and is probably the most important

    "extra" that can be carried. Stray ight is apt to strike thelens from so many unsuspectedquarters that the ontyreallysafe ule is: olwoysuseo lenshood,no matter where,when, or what you are photographing.It is even more important to use the lens hood with acolour f i lter or supplementaryens,sinceboth add reflect-ing surfaceswhich increase he effectof stray l,ight. 47
