It is the purpose of these notes to point out to the student of architecture some facts of chiaroscuro, and to tell him how these facts may be rendered in washes of water color (sepia), that he may make the representation of a building. The two methods of rendering perspectives — by ink lines Pen inferior to drawn with the pen and by washes of water color — cannot brush. be compared. The means employed are totally unlike, and the results obtained almost as unlike. The lack of truthfulness and the meagre power of expres- sion in the pen-rendered perspectives led to the formation, in the School of Art and Design of the University of Illinois, of a class in Sepia Rendering, made up of students of archi- tecture. These notes contain virtually the same matter as is there i„ university of given in class lectures, and the exercises here reproduced iii'""'s- show the manner in which the work is taken up. To prove that this method of rendering is successful we have but to look at Plates III., IV., V., VI., VII., VIII., IX., X. and XIII., all of which were rendered by students who woru of students. devoted one term, or twelve weeks of nine hours each, to this class of work. Plate III. is the work of Ernest N. Braucher ; Plate IV., of Charles B. Young ; Plate V., Rans- ford M. French ; Plate VI., Herbert E. Hewitt ; Plate VII., lo Architectural Rendering in Sepia.

The plates not to It is not cxpcctcd that the student will use these plates as be copied. copies, but rather as suggestions for his own work. As these drawings are reduced from the original size, it will be impos- sible to get the same effect even if drawn to original scale. The exercises should be followed, and the drawings here given used as copies for method and effect only. It is supposed that the student taking up this work already Student must understands perspective, and is able to make an accurate understand per- . .,.,,. . , , spective. drawmg — a copy of a buildmg, or a perspective trom plans and elevations of a building not yet erected. It is al-so sup- posed that he does not possess a great amount of artistic ability, but is willing, by hard study and the acceptance of many defeats, to work through a series of exercises, which, if he works conscientiously, will enable him to make a true and graphic picture. Aim of exercises. j^e g^d and aim of this course in Sepia Rendering is to prepare the student for working directly from nature, or for rendering ideal effects of light and shade upon his own per- spectives. ■j^ r 1^ ^ 'i?^ ff _ .

IN a perspective rendered in sepia (or any other mono- chrome), everything except color — form, character, relation to surroundings and position in space — can be expressed by means of values of shade. By value Vau. meaning the intensity of light and shade as compared with other parts of the object, or accessories. And color can be suggested by giving a value for it. The real color of objects is called their "local color"; this local color is much affected by light and shade, and in- creases the difficulty of the architect's problem. It will be L.uai color. seen that the shade on a white house cannot be like that on a red one ; and if a house is white it must be so handled as to suggest white ; if red, red. To express this, different scales of shade have to be adopted when several buildings, scales >.f value. unlike in color, are rendered in the same drawing, in order that the local color of each may be expressed. In an art school, the student is placed in a studio where a steady light falls upon a cast or group of objects. It is then pointed out to him that the object, intersecting the light, has one side in light, the other in shade, that a shadow is cast, and to truthfully represent this is the student's problem. This is precisely the problem before the architect. He has The architect's a building to represent ; the sun shines and illumines a part i'™ of it, another part is in shade, and a shadow is cast. The 12 Architectural Rendering ifi Sepia. A solid buililins; surrounded liy atm(ts[iliurc. Repose demanded.

It must be en- veloped in atmosphere, and take its place in the picture near or far, as the case may be. It must hold proper relation with the sky, the trees, and the buildings about it. The values of all things in the picture must express not only solidity, but color, and give an effect of reality. A water color drawing is not the rival of a photograph ; it should accentuate the essential and characteristic features, subordinate detail, and. by masses of light and shade, give the effect of repose without which there is no resemblance to nature. The architect must learn to generalize and to express much in a simple way ; he must learn what to leave out, as well as what to put in, to suggest without fully stating ; in fact, he must not try to draw every moulding, every pane of glass, every joint between the bricks, every leaf on the tree ; he must not see reflected lights that cut the shades, giving variety where simplicity is needed ; but he must suggest all these by rendering his building in simple flat washes, with detail judiciously introduced where a little will suggest much. He must learn to sacrifice little things that the great may be expressed. The student of chiaroscuro must learn to look at things simply — there is a mass of light and a mass of shade. These various " planes of shade " have a certain shape as well as value. Look at the building as made up of these planes or values, not as a collection of walls, towers and windows ; and when working consider them as parts of one whole, never increasing the value of one part without due regard Shape of cast si.ad- to all othcr parts. Remember that the shape of a cast °'''^- shadow depends upon the shape of the object casting it, and the surface over which it falls ; and that shadows are darker and more distinct near the objects that cast them. And, Look at simplv. things C/iiarosc7tro. 13 finally, strive for " breadth," which is obtained by means of Breadth, intermediate shade, not by abrupt contrasts. The facts of chiaroscuro are the same whether one color is used or many. The method of handling to be described applies equally well to color rendering, but the student *'°'°'^' should not attempt color until he is quite skillful in the use of monochrome. An architect has no more right to give his client wrong Be truthful. impressions of color than he has of form or cost. A color effect, quite true to nature, can be obtained by going over the sepia drawing when completed with flat washes of color. When this is done, light surfaces should coior over sepia. be given very slight values of sepia, as the color has a ten- jdency to increase value as well as give color. II. COMPOSITION Composition fined. de Study nature. Beware of confu- sion. " In all good compositions you will find three most important qualities — simplicity, breadth and character — and these are gained, not by rules, but by feeling for good drawing and color." — Sir Joshua Reynolds. FOR the. last word in this quotation read "value," and it will be equally true. All artists, in their work, consider three things — the quality and position of lines, the size, shape and position of areas of dark and light, and the color. The arrangement of these lines and areas to express an idea is composition. The problems in composition are as numerous as the num- ber of drawings. No rules can be given, and but few sug- gestions made. Every architect who makes perspectives of his buildings is advised to observe buildings already erected from different positions and under different conditions of light ; and, by so doing, he will absorb a feeling for form and for light and shade to be gained in no other way. Care should be taken, in laying out a perspective, to have the most interesting and prominent features of the building near the centre of the drawing. Choose .such a position that the building will compose simply without confusion of members ; and, where several are to be in the same composition, simplify the drawing of those in the distance into ma.sses of value, for a confused composition can never invite the attention. Whatever is Composiiion. 15 done be truthful ; the building in the picture must have tne same scheme of light and shade that it will have in nature ; that is, the shadows must be cast in the same direction that they will be cast by the sun, even if we have to sacrifice something of interest in the drawing. The part of composition that particularly concerns the student of Architectural Rendering in Sepia is the treat- ment of light and shade. It is the province of light and shade to give solidity and Light and shade. an effect of reality to the drawing ; to bring out, by the various values, the proportion of the building ; and by its shadows of cornice, gable and projection add interest and beauty. It is also the province of light and shade to coun- teract any disagreeable tendency of line, ^nd to set forth the beauties of the building in every legitimate way. It is a mistake to make much of the accessories. The architect is not a painter of scenery, and he is lessen- simplify accesso- ing the effect of his work by burying it in imaginary foliage, or surrounding it by Arcadian landscape, which outweighs in interest the building itself. He should add truthful, agreeable and proper surroundings suggesting the location, and these should be treated as a foil to enhance the beauty , and add to the interest of his building^. A good atmospheric effect can be obtained by making the sky grade to light near the horizon, and, if masses of The sky. foliage flank the building, make them lighter than the build- ing on the shade side and darker on the light. • Horizontal clouds growing nearer together as they ap- proach the horizon give an effect of distance ; a sky so treated as to be dark at the horizon and grade upward will give an effect of height to the building. If the building is simple and expressed in large masses it is well to give variety to the sky by cloud forms; if it is Contrast (if sky 1 1 111 I • *^"^ huilding. complex and cuts the sky by many chimneys, towers, etc., 1 6 Arcliitechiral Rendering in Sepia. the sky should be simple. Where Uttle sky is seen, it should be expressed by a flat wash. To prevent a heavy and mechanical effect, equal quanti- ties of light and shade should be avoided. Generally it will be found better to have more space about the lig^ht than the shade side. Beware of long continued lines, as a cornice ; break them by a play of light and shade. F III. HANDLING. "^IRST strain the paper, though if the accessories in- troduce distant hills, masses of foliage, etc., it will be well to first draw the general outline of the building and wash in the distance while the paper is moist. The sky can be put in when the paper is in this state study the subject without fear of hard edges, and, when the paper is dry, com- ^^iL ^^^" plete the drawing. " Modern Dutch " methods cannot be successfully em- ployed in architectural rendering. The student should make a very careful drawing. Wher- ever there is width or thickness, lines should be drawn to express it. Such small lines as the joints between bricks, stones or slates should not be drawn in pencil. The student will find it much easier to cover some un- necessary lines when laying washes, than to determine the The drawing. shape and area of washes without lines to aid him. As he gains command over his materials, he will depend more and more upon his brush, until, when rendering simple build- ings, the principal long vanishing lines and a few verticals to give widths will be all that he will require ; the drawing will be made largely with the brush.

Experience alone will show the proper grade of pencil to use. Erase as little as possible on water-color paper, and that with a soft eraser, that the texture of the paper may not be destroyed. In the finished drawing no lines whatever should be seen. We see buildings as masses of value relieved against each other by their value, not by their outline. We realize that one wall is nearer than another because it appears lighter or No outlines in darker ; there is no line where these values meet, therefore nature. ^^^ exprcss thcsc surfaccs by laying washes of proper value side by .side, and not by drawing lines where these values meet. The drawing completed, pass over the paper with a large Wet the paper brush or soft spougc, wctting the entire surface, and at once take up the superfluous water with blotting paper or a soft cloth. If a large surface is to be covered, it is well to leave the damp cloth on the lower part of the sheet, that the paper may not dry before it is reached. A flat wash To lay a flat wash, incline the board slightly and, while the paper is yet damp, with brush full of color pass along the upper edge of the space to be covered, whether large or small, forming a pool or wave of color. Keeping the brush full and holding it at right angles to the paper, coax this wave to flow slowly down the paper, keeping it moving evenly and allowing no part to .stand longer than another. On no account " drag " the color or try to "paint it on," but let it settle on the paper as the wave passes over it.

It will be well to copy Figs. 3 and 4 of this plate before workino- throusfh many of the exercises, and then, having finished them, return to this problem, and, with two or three graded values, render it with the power gained by additional knowledge and skill. To obtain the best results, the student should now work directly from nature ; if this is impossible, it will be well to render subjects made up largely of landscape or sea views, sup-o-estions for which can be found everywhere. (See Plate XII. These cottages were rendered from small pen- mtc xii. sketches found in a catalogue of architectural publications.) The aim of the student should be not only to produce a true and beautiful picture, but to produce it quickly. He should endeavor, for obvious reasons, to take advantage of everything that will aid him in obtaining effects in the ^..i'ckiy.'' shortest possible length of time. EXERCISE. Y. FOR PRACTICE IN RAPID SKETCHING. A good exercise to cultivate the power of quickly decid- ing what is to be done and the best way to do it, is the time sketch. In this the student limits himself to a certain 'the time .ketch, period, and in that time attempts to do a certain amount of work. For example : Sketch a picturesque sea-side cottage in ninety minutes. Sketch a clock tower for town hall in sixty minutes. Sketch a gateway for city park in two hours. sketches. 40 Architectural Rendering in Sepia. The ability to put thoughts upon paper quickly and beautifully expressed is of the greatest advantage to the "Time is money." architcct, hol only froHi an artistic but from a financial point of view.

Plate XIII. is a time sketch rendered in ninety minutes, and the two sketches on Plate XII., by washing in the large Keep several valucs whilc the paper was wet and the finishing values of drawings going at once. oiic whilc the Other dried, was rendered in but little more time. If these notes are being worked through systematically, as by a class of architectural students, it will be well to set Competition asidc oiic day per wcck for a time sketch. It will add to the interest if some competent person assigns the problems, and, at the end of the time, criticizes the drawings. This work will prepare the student for sketching from nature. Skill comes only To attain skill, sketch constantly; no building is so small or simple as not to present a good problem. When sketching from nature, do not be confused by the light and the apparent importance of detail, but look only for large masses of light, shade and shadow. Art must always fall far short of nature, for white paper can never rival sunlight, or the pigments of the palette do more than suggest nature's coloring. In our work of rendering architectural subjects in sepia, we select what will add most to our buildings, and, since we cannot express everything, make as little as possible of all that does not add directly to the efi^ect of solidity and sunligrht. with practice. ^#5 ?— ^ , ^.^^'it. \Mi : m i\ Ml ixl I ■^ CD -M^; S^^ ^^P# UCLA-AUPL • NA 2780 F8 UNIVERSITY OF CALIFORNIA LIBRARY, LOS ANGELES Architecture & Urban Planning Library, 825-2747.
