Description

Post-flush formula color standard egative film using method and producing device

(1) technical field

The invention belongs to post-flush formula color standard egative film method for production and producing device that colour enlarger accent machine is used

(2) technical background

The enlargement of color photos machine of present domestic use, no matter be import or homemade, no matter what its optical system adopted is additive color process, or subtractive color process, no matter be the high light control type, still the white light cut-off type of losing lustre, no matter have or not erect image to show, its principle all is measure the process colour negative red, green, blue 3 kinds of coloured light, convert three voltage signals to by photoelectric device (as blue silicon or CCD scanning), the power of these three voltage signals, corresponding with three kinds of color average densities on the colour negative respectively, and three signals are sent into electronic control circuit compare and computing with the standard signal in circuit, set according to color standard egative film parameter, output signal then, control shutter and color filter move, and make the photochrome of a success.But because a variety of causes, the color change of colour negative is very big.Such as the colour correction mask color difference of different brands colour negative, the difference of photography conditions, the cameraman uses up accurately whether to wait to be influenced different to the colour negative color.Therefore to manufacture separately color standard egative film to the colour negative of different brands.Also to make several color standard egative films according to colour negative exposure latitude range size.As three, four or five, be respectively under-exposed, exposure is normal, and is over-exposed, makes it the impartial colour negative effective latitude scope that covers, and uses with the slope control and the multichannel that adapt to different enlargement of color photos machines.Manufacturing of color standard egative film is the principle that set of applications arrives ash (integrated ash).We know the most difficult performance of grey in the photochrome, if different color in the common scenery is superimposed, its integrated result is similar to neutral gray.The method of integrated ash has quick and easy characteristics, and nearly all enlargement of color photos machine all adopts this negative film assessment method.

The color source of the color standard egative film that present domestic enlargement of color photos machine uses mainly contains two approach.One is that each colour film production firm shooting is manufactured, such as companies such as Kodak, Fuji, Lekais.And be under the shooting condition of strictness, to expose, and developing under the standard technology condition separately, sell or give each enlargement of color photos shop use then.Should this standard film be very accurately, but really not handy in the accent machine process of most at home enlargements of color photos shop, can only be when adjusting the film processor slope as a reference.(adjusting slope in fact neither be very accurate).The reason that causes this result is not of above-mentioned normal negative itself, but the washing condition of our domestic most of enlargement of color photos machines and standard flush parameter have bigger deviation, even very big deviation is arranged.And depending primarily on the deviation of Punching and rolling machine, the best approach that wants to address the above problem is the developing technique that each enlargement of color photos shop should strict operative norm and adopts strict product control means.But most enlargements of color photos shop is difficult to accomplish.Its reason is as follows:

One, we know that modern colored job operation has developed into high temperature, quick, anhydrous, low toxicity, few discharging and of low pollution stage.By Kodak first-elected C-41, C-41B, C-41RA dash volume technology and RA-4 dash paper technology, although its liquid formula is maintained secrecy, other company produces both at home and abroad dashes medicine and also all adopts above-mentioned technological standards and draw close to it.As companies such as Fuji, Lekais, though and the medicine liquid washing result of different brands has certain deviation, this deviation is also little, each manufacturer has also formulated strict developing technique standard simultaneously.As the monitoring of the control of physical condition, soup chemical analysis, sensitization monitoring etc.Wanting the above-mentioned standard of strict execution needs soup production firm and each enlargement of color photos shop to closely cooperate, and both sides drop into relevant detection instrument and test material jointly, is all done the testing and the corresponding correction work of repetition every day by enlargement of color photos shop technician.The washing condition that could guarantee the equipment of developing like this within the standard-required scope, to accomplish this point, still all there is sizable difficulty in manufacturer concerning the enlargement of color photos shop.

Two, China or a developing country, the equipment situation that use in domestic each enlargement of color photos shop is also complicated.The advanced type of a spot of import is wherein arranged, but be that the import second-hand equipment is extending service in the army mostly, a large amount of homemade new used equipments is also arranged simultaneously in work.

In sum, we can say that the standard that the washing condition in domestic most of enlargements of color photos shop and soup manufacturer formulate all has more greatly even very big deviation, and want to correct and come to be difficult to again.

It is that each enlargement of color photos shop oneself is taken that another source of standard film is used in domestic enlargement of color photos shop at present, is to take hawk, personage or other scenery under normal daylight or artificial light sources lighting condition.Use for the accent machine by Punching and rolling machine flushing back separately then.Though effect is not very desirable, and is available reluctantly.Its reason is because shooting condition is difficult in the scope of the standard of being controlled at.

The image pickup method of existing color standard egative film generally all is to take hawk, material object or portrait.What that is to say the film impression is the light that is reflected by object.This method is subjected to easily because the reflective colour cast influence that causes of light source, the intrinsic colour cast of subject and shooting environmental.

(3) summary of the invention

The technical problem to be solved in the present invention provides a kind of post-flush formula color standard egative film using method and producing device.

The producing device of post-flush formula color standard egative film comprises light mixing cartridge, light-intaking tube, flashlamp, color meter, light meter.Light mixing cartridge and light-intaking tube surround by the light-proof material of interior subsides reflective membrane, the top of light mixing cartridge and light-intaking tube links, form path channels, this path channels is provided with a vertical plug-in type aperture, the middle part level of light-intaking tube is inserted with a color filter group, the light inlet place of color filter group below is equiped with an X-flash, and X-flash is connected with a stabilized voltage supply, and stable light source is provided.The middle part of light mixing cartridge has been horizontally disposed with a diffusing panel, and its bottom level is provided with a transmission hawk, and its bottom margin has extended a conically shaped downwards, and the lower port of conically shaped is equiped with camera.

Can install one or more reflectors respectively in above-mentioned light mixing cartridge and the light-intaking tube.

The using method of post-flush formula color standard egative film is: adopt transmitted light take film after the exposure at the end before flushing, offer the free flushing of client after, use for the accent machine.So require its Punching and rolling machine washing condition relatively stable, no matter bias free is arranged, bigger deviation is arranged still, so long as relatively stablely just can normally use with standard technology.Owing to the change of normal wear in using and washing condition (as the soup of changing different brands, the type of changing planes, change washing condition, parameter etc.) causes the accent machine unpunctual, can consider the normal negative that more renews, replacement cycle is difficult for long, is generally 3-6 month.

The present invention is owing to be in the light path of sealing, and transmiting colour temperature by saturating look hawk is that the light of 5500K is taken and to be formed, thereby can avoid because of taking the reflective colour cast influence that causes of intrinsic colour cast of thing and shooting environmental.In addition, color standard egative film of the present invention does not wash after the exposure, and by each enlargement of color photos shop oneself flushing, thereby can adapt to the different washing condition in enlargement of color photos shop, satisfy mediation needs separately.
