The Barnet Book of Photography Part 8

[Ill.u.s.tration: Fig. 12.]

For the sake of training one's perceptions look at any good pictures, and in your mind resolve them into line diagrams and see how these lines fall, and in considering any landscape or other subject to be photographed make up your mind as to what lines are suggested, and then select your point of view so that these lines balance or are symmetrical in arrangement, and also that they converge towards some point well within the picture, and near the centre of it.

[Ill.u.s.tration: Fig. 13.]

But in fig. 13 we have a subject in part well composed, but the composition is spoilt because of the line formed by the road and fence, which seem to cut the picture in two, whereas could we have chosen the same subject from a point of view giving such an arrangement as fig. 14, a difference is at once felt and a more pleasing effect gained.

[Ill.u.s.tration: Fig. 16.]

Lines which seem to separate us from the picture and cut off one part from another must be carefully avoided, and an endeavour to find something which will, as it were, lead the eye into the picture, should be diligently sought for, and indeed a subject, however it may interest us, must often be abandoned if it lacks those things which go to make pleasing composition, remembering as we should always do that in pictorial work the fact that objects are curious, or interesting, or pretty, has nothing to do with the case, but that they are only to be valued according as they act as media for expressing pleasing ideas, beautiful thoughts and sentiments, which they will not do if some part creates a feeling of unpleasing arrangement or design. If a scene does not compose well, we should as pictorial workers feel no desire to reproduce it. But you may say "Cannot we often by changing our point of view get an otherwise ill-composed subject to compose well?" Most decidedly, that is precisely what we should do, but it is no longer the same subject or view.

And now let me say that it is often surprising how much alteration may be made by changing our position. Figs. 15 and 16 are together an instance of this, the outline here given being made from a pencil sketch made on the spot, whilst figs. 17 and 18 are examples of the desirable change brought about by watching and waiting for a change in the position of light and the condition of the river's tide.

Where the beginner most often fails is in taking things as they are without pausing to consider whether they might not be improved, and if so in what way, and then patiently searching to see if such better way can be found.

Pictorial success will as often as not depend on the exercise of fastidious taste, which is satisfied with nothing but the very best, and not quite content even then.

A great deal more might usefully be said with reference to the composition of lines if s.p.a.ce would permit, but this general reference may be given as a sort of summing up.

If the disposition of the lines const.i.tutes such a perfectly symmetrical design that it is at once recognised as symmetrical, then it is wrong, because the artifice by which pleasing composition is attained is betrayed, and we feel the thing to be artificial. If, on the other hand, the lines fall so as to make the beholder conscious of their presence, as, for instance, cutting off a portion of the subject or presenting a one-sided appearance, again it is wrong. _In neither case should the lines or the objects suggesting them be felt at all until sought for, neither as being very right or very wrong._

In art it is a maxim that the means by which the thing is done should not proclaim itself, and hence it must apply to pictorial photography, which is an effort after the artistic. A composition should please without our quite knowing why, and without our being able to see the machinery, as it were, by which our pleasurable sensations are set in motion.

But whilst it is convenient to speak of _lines_ in the landscape, it is only a manner of speaking, for, as we know very well, photography, unlike pen drawing, has to do with "tones," that is, _ma.s.ses_ of light and shade. Now the general rules suggested as regards the arrangement of lines, apply in much the same way if we regard a picture (as we should do) as consisting of ma.s.ses of light and shade.

If when standing before a picture we close the eyes and then suddenly open them, our attention is certain to be drawn to the highest light or the deepest shadow, and hence, as a general rule, whichever of these is the strongest to attract attention, that should be in or near the princ.i.p.al object (indeed it will make of itself the princ.i.p.al object), and should therefore be well removed from the margins of the picture.

Refer back to fig. 8, in which the light patch of sky, the light in the water and the two cl.u.s.ters of light rushes, all form competing points of attraction, and if these are too near the margins, they remind us of those margins, hence the improvement in effect when these are cut away or left out.

But disposing of the highest light and deepest dark does not finish the matter. There is a certain relative degree of lightness and darkness between everything in nature. Moreover, colours have to be interpreted by certain degrees of light and shade according to the distance objects are away from us, and according to the amount of light falling on them.

Such relative lightness and darkness is called "_tone_." The word used in this sense has nothing to do with "tone" as applied to the colour of a print, which colour we change by a process we call "toning," and upon the correct rendering of relative tones so much of the effect of a picture depends, and so much of its emotional qualities.

Generally speaking, although there are often exceptions, the further an object is from us the grayer it seems. White becomes less white, and dark objects grow less dark, until in the distance both, under ordinary circ.u.mstances, come almost to the same "tone," and we see the distance only as a gray hazy ma.s.s.

If for a subject we have a figure of a woman by a stream of water and we make an under-exposed negative of it, or develop the negative to too great a density, we shall very likely have a print in which the water and the woman's ap.r.o.n and cap come very much whiter with regard to the rest of the subject than ever they appear in nature, whilst the distance will very likely come too dark. Here we show a disregard for the correct rendering of relative tones and the effect is hard and harsh, unlike nature. We must therefore endeavour, both in exposure and development and printing, to preserve relative tones exactly as they are in nature, and constant study and observation of nature should be carried on in order that the eye may be trained to know how things come relatively in nature, and so be able to decide at a glance if the photograph is good.

Ultimate success, by the way, often depends less on knowing what to take and how to take it than on a well-trained judgment which knows what is good or bad when we have taken it.

Whilst the mere lines or forms of objects may impart some amount of feeling and sentiment to a scene, inasmuch as there is restfulness and repose in the long horizontal lines of the river-side pastures, something rhythmical in the sinuous curves of the winding stream, or vigour and variety in the irregular forms of the rugged cliffs and so on, yet the ideas and feelings which the picture will promote depend more on the lights and shades, and the ma.s.ses contrasting or merging each with each.

But Nature does not always present herself in pleasingly arranged ma.s.ses, and is consequently at such times commonplace and unpicturesque in the literal sense of the word. At such times she will not attract the pictorial worker any more than she will when perchance the lines and groupings are unsuitable.

The landscape which basks under the full blaze of sun, glittering throughout every inch with a myriad twinkling lights and sharp details, awakens no feeling akin to those which probably everyone feels when in the twilight of evening plane after plane recedes as one broad flat tint behind the other. Under the bright light of day we may wonder at the richness and plenty upon the earth, we may rejoice in that there are so many curious and pretty things to look at, but these are like the feelings inspired by reading a book on natural history, rather than the emotions created by the perusal of a poem, or listening to sweet music.

[Ill.u.s.tration: Fig. 19.]

Compare for a moment the two photographs, fig. 19 and fig. 20.

The first is by no means an extreme case of the ordinary photograph, and notice that although the composition is fairly good as far as grouping goes, there is an absence of any quality which might make one feel anything outside the bare recognition of the facts depicted, but the second, if it be good at all, must depend for admiration on a certain amount of sentiment which it suggests or creates. You will notice that in the first there is no sense of distance, and although a church tower, behind the masts of the boats, is half a mile or so away it does not possess the "tone" and veiling of atmosphere which would make it appear distant. Every part of the view seems equally near, or nearly so; the eye wanders over the whole, alighting on details here and there which interest and amuse, yet there is an absence of just that breadth which is noticeably present in the second example.

[Ill.u.s.tration: Fig. 20.]

Now let it be distinctly understood that detail, its omission or suppression, and its introduction or sharp delineation, is not a question of lens focus only, or even chiefly, but it is largely a question of light. Imagine the photograph, fig. 19, with the greater part of the detail taken out so that the quay, the houses, the sh.o.r.e, etc. were just broad ma.s.ses of lighter or darker tone, should we not then get a composition which would be less disturbing, more compact, more concentrated in interest? Is not this the case in fig.

20, in which detail is almost entirely absent? And yet detail could not have been truthfully introduced in this photograph, because with the light in the position it is, and in the misty evening air, _no detail was there to reproduce_; it was the fact that objects ranged themselves in ma.s.ses one against the other, leaving room for imagination and creating ideas that determined its selection and its consequent portrayal.

In many cases a clear and sharp delineation of details will perhaps be desirable, not, however, for the sake of showing detail, but just so far as the production of the effect may require; on the other hand, just the full amount of detail that a lens will give is by no means always wanted.

_Lenses were not invented for pictorial purposes_, and therefore there is no reason for concluding that what the lens gives is necessarily right, for remember that we started with the distinct understanding that we were merely _applying_ to a certain purpose just so much of the photographic process as we considered we needed; because I have the means of travelling at sixty miles an hour there is no reason why I should not apply the same means of locomotion to coaching a pedestrian at a tenth of that speed if I choose. It may be said that in the two photographs referred to the comparison is not a fair one, because so much depends on the sky. Granted that much in the second example does depend on the sky, which is an essential part of the picture, and indeed one cause of its very existence, but in the other (fig. 19) the presence of clouds would not improve the pictorial faults to which reference has been made.

As a mere record or portrayal of Old Woodbridge Quay, the absence of clouds is as much a characteristic of its particular species, as the clouds in the second one are inseparable from its existence.

So, but little more than half hinting at the principles involved in the due suppression of unnecessary details, and the elimination of undesirable objects in order to obtain breadth, and having said but little as to the preservation of correct relative values or tones, I must pa.s.s on.

Every corner of nature's broad expanse is, as it were, enveloped in atmosphere, and invisible as we are commonly in the habit of considering it to be, it affects to a greater or less degree everything we see, and the visible atmosphere is often responsible for some of nature's most beautiful and most appealing aspects.

Obviously then we cannot afford to leave out so important a contributory to picturesque effect, and it is on this account rather than on account of sharp or un-sharp detail that the question of stops and lens apertures comes in.

Look at the image of a landscape on a moderately hazy day, as it appears on the ground-gla.s.s focussing screen of your camera, using the lens at full aperture--then quickly insert _f_/32, and notice the difference. Not alone have objects near at hand and more remote become more sharply or more equally defined, but you may also notice that objects are _more brilliant_, and that a sense of atmosphere has been cut out.

Compare if you will two photographs, the one made respectively with full aperture of _f_/6 or _f_/8 and the other made with _f_/32 or _f_/45, and provided that in the first case we have not actual blurring to the extent of destroying form and structure, does not the first remind you more of nature? I do not say it is so instructive, so surprising, so dainty, or of such exquisite finish, but is it not more reminiscent of the _effects_ we remember to have seen and _felt_ in nature. It is not the function of this article to say to what optical laws this difference is due, and yet the student may expect to receive something by way of practical working instructions.

My recommendation is then to use a single landscape lens or the single combination of a doublet, and in starting to use the full aperture.

With this it may be that when the foreground is moderately sharp, trees more remote are so ill defined as to appear as a collection of little blots and irregular patches. Whilst sharp detail in all places may not be productive of pictorial effect, yet the extreme opposite will be displeasing in another way, and it will be best to secure just _so much definition and no more_ as shall save the representation from appearing to have been wilfully put out of focus--once let the destruction of detail be obvious and we betray the artifice by which we are working, which is just what we should avoid.

In the case just supposed then, we may now introduce the first stop, simultaneously racking the lens in a little until we get middle distance without unpleasantly obvious blurring. The foreground may be a little out of focus, and in practice I find it is rather helpful to general effect if detail is sacrificed more in the foreground than in the middle distance.

This I believe is contrary to the teaching of many, but my feeling is that with a sharply defined foreground the eye is attracted and the interest so far arrested, that it is difficult to travel further and enter into the poetry and sentiment of the scene beyond.

Wide-angle lenses have a double disadvantage, shared in part by so-called rapid rectilinear doublet lenses. In the first place they flatten the view, bringing distant planes to appear as near as the nearer ones, and by including a comparatively wide angle they bring into the plane of the foreground, objects so near that they appear out of proportion, and hence proportions are false when judged as the observer must judge by the standard of visual perspective.

A long-focus, narrow-angle lens necessitates a camera which racks out to a considerable length, and probably a greater extension than any camera in the ordinary way can give, would be an advantage on some occasions.

Pa.s.sing reference has been made to the interpretation of colours in nature in their true relative value of black and white.

If we have a subject in which brilliant orange-coloured rushes in autumn are seen as glowing bright against a background of dark blue water, and the rushes made still more golden of hue by the ruddy rays of a sinking sun, a difficult case is before us.

Such a case I remember very well in the south of Devons.h.i.+re, close to what is known as Slapton Ley. It was late afternoon in November, and from over the rounded hills behind me to the westward, the declining sun sent warm red rays on to the belt of faded reeds which stretched out into the expanse of the still land-locked water of the Ley--a great sheet of fresh water which placidly lay under the shelter of the bank of s.h.i.+ngle which alone separated it from the ever-restless sea--placidly listening to the ceaseless voices of sea music, and at this particular hour reflecting the sky deep blue and of almost leaden hue--just above the bank rose the full moon, orange in tint, on a background of blue-green sky--the yellow reeds, kindled into glowing amber tints by the sun's rays, flamed out from the deep blue water--yellow the s.h.i.+ngle bank against the blue water and green-blue sky, deeper yellow the moon as it rose from out the sea. So grand a scheme of colour that by its side the essays of the most daring painter might well seem feeble, so exquisite a poem that the intrusion of the photographer, a.n.a.lysing the values and tones and calculating his powers of reproduction seemed like sacrilege. In the main it was yellow, orange-yellow, and red standing out as luminous against the deep blue of water and only a little less blue sky. It was gorgeous non-actinic colour appearing as _light_ against a highly actinic but _darker_ colour. The consequence of an indiscreet exposure with an ordinary plate might be antic.i.p.ated to produce _dark_ rushes against a _pale grey_ background of water, and so probably the very effect we were minded to secure, reversed and dissipated.

This is an extreme case, perhaps, but throughout the whole range of nature the contrasting and blending of adjacent colours is so subtle a thing that I should feel one were throwing away at least a possible advantage by not using colour-corrected or isochromatic plates on nearly every occasion, and in order to get the full advantage of isochromatic plates, I should consider the addition of a yellow screen an essential.

The rapidity of one's plates, isochromatic or otherwise, must be governed entirely by the nature of the subject, as also to some degree must be development and subsequent printing.
