against the grain

1. Contrary to custom, one's inclination, or good sense.

[Middle English, from Old French graine, from Latin grānum.]

Photography:

1. Relative size of the particles forming a photographic image, expressed in terms of fine-grain or coarse-grain images.

2. Flaws in a photograph caused by excessive enlarging.

Printing: direction in which most fibers in paper run as a result of the papermaking process. Paper tears more easily with the grain than against the grain, and when the shape of paper is affected by moisture, or by a lack of humidity, it changes more in the direction of the grain. For some types of paper, folds made parallel to the grain will cause less damage to the paper and will be less bulky. Other types of paper must be folded against the grain.

The pages of a book or catalog turn more easily if the grain of every page runs parallel to the binding. However, advertisers often place bind-ins so that the grain of the bind-in crosses the binding, causing the magazine or catalog to tend to open at that point. This works especially well if the bind-in paper stock is heavier than that of the pages.

For offset printing, the grain should be parallel to the long edge of the printed image so that changes in the paper shape due to moisture will have less impact on the print register.

Many other rules apply to different types of paper and printing. Your printer or production manager should be consulted when choosing the appropriate paper for a job.

Symbol gr. Adverting to the seed of wheat, barley, etc., the grain is a long-standing elementary unit for measuring mass, and has been used for length too. In Britain the initial entity was the barleycorn, the seed grain of barley, specifically two-rowed barley.

mass The grain, originally the UK troy grain, is the common elemental unit of the avoirdupois, troy and apothecaries' scales in the UK and the USA. Defined originally by barley grains ‘neither small nor large and taken from the middle of the ear’
[Connor R. D. The Weights and Measures of England (London: HMSO, 1987)] the unit of modern times differed minutely between the UK and the USA until the agreed international standard
[Nature Vol. 183, 80-1 (1959)] was implemented in 1959 (though in UK not exclusively until 1964).

The grain was officially abolished for the UK in 1985.The UK Weights and Measures Act 1985 explicitly excluded from use for trade the bushell, cental, chain, drachm, dram, fluid drachm, furlong, grain, hundredweight, ounce apoth., peck, pennyweight, quarter, quintal, rood, scruple, stone, ton, the square mile, cubic inch, cubic foot, cubic yard, and the term ‘metric ton’. However, the legal status of the bushell, fluid drachm, and peck had been repealed, along with all apothecaries' units and troy units other than ounce, by Order in 1970. Besides the remaining BI units and the simple SI units, the Act included the kilometre, decimetre, centimetre and millimetre, the square metre, square decimetre, square centimetre and square millimetre, the hectare and decare along with the are, the cubic metre, cubic decimetre and cubic centimetre, the hectolitre decilitre, centilitre and millilitre, the tonne (or ‘metric tonne’), kilogram, hectogram, milligram and carat (metric). All had been included in the similar Act of 1963, but with some variation of name: -gram was -gramme, decare was dekare, the tonne appeared only as metric ton.

Internat, BI, US-C, Australia, Canada, New Zealand, etc., 1959 64.798 91 mg (0.323 994 55 metric carat of 200 mg). prev Within 0.01% of the above for centuries; see pound for details.

History

The avoirdupois scale (see ounce and hundredweight) has a pound of 7 000 grains = 16 oz of 437.5 gr; both the troy and the apothecaries' scales have an ounce of 480 grains, but a pound of only 12 ounces, giving 5 760 grains to the pound. The latter two scales differ in their intermediate subdivision. Comparative values across the three scales are shown in Table 21.

weight, force See gravitational system.

1. The direction, arrangement, or appearance of the fibers in wood, or the strata in stone, slate, etc.
2. The easiest cleavage direction in a stone.
3. Any small, hard particle, as of sand.
4. A unit of weight measure in the English system of units; 7,000 grains equals 1 lb; used as a measure of the weight of moisture in air.

Grain is a curious blend of the quantifiable and the subjective. It may even create an impression of more sharpness than exists: a grainy enlargement from 35 mm may look sharper than a grainless enlargement from a larger format. In conventional monochrome films, actual particles of silver make up the image; in colour films (and chromogenic monochrome films) dye clouds are formed in proportion to the silver halide image that is later bleached out.

Graininess can be quantified as granularity, using a microdensitometer trace, though differing methodologies limit the usefulness of comparison between the results achieved by different researchers: the only meaningful comparisons are between films tested under the same conditions, usually by the same laboratory. Granularity figures are normally expressed as root mean square (RMS) values of the density fluctuations over the trace.

Subjectively, some kinds of grain are simply more pleasing to the eye than others: ‘crisp’ (clearly defined) grain usually looks better than mushy. Both quantifiable and subjective qualities may be modified by film design; developer choice; exposure (more exposure means coarser grain, except with colour and chromogenic monochrome films); duration of development (more time means more grain); and agitation (more agitation means more grain).

Although grain and sharpness are related—slower films tend in general to be finer grained and sharper than faster ones—there is a trade-off between the two at any given speed: the sharpest films are rarely the finest grained, and vice versa. A slow, fine-grain film in a speed-increasing developer will normally give finer grain than a faster, coarser-grained film in a fine-grain developer.
