Henry Taylor was an early photographer in my home county of Surrey. His business was as a Chemist , druggist and bookseller. This article was originally published in the International Annual of Anthony's Photographic Bulletin in June 1889. It offers an insight into the world of the Calotype in the 1850s and Henry Taylor plainly looks back to these formative years with fondness.

THE CALOTYPE PROCESS, AND HOW WE PHOTO-

GRAPHED IN THE  FIFTIES.

By H, D, Taylor*

I am indebted to the Hon. Arthur Kerr for my introduction to

photography. In the year 1853 he was staying in my neighbor-

hood (Godalming), and as he had just been taking lessons from

 

•Thirty years ago Mr. Taylor stood in the front rank of Bnglish photographers,

the contemporary criticism on his work in the Athenaeum Art Journal etc., certify this.

Mr. Buckle, of Leamington, in ,calotype, he offered to instruct

me in its mysteries. On the principle "palmam qui meruit

ferat" I should prefer to call the process "Talbotype"; as Mr.

Fox Talbot was its author.

I was anxious that my success should not be marred by the use

of imperfect instruments, I therefore procured from Ross a cam-

era to take pictures 8 1/2 x6 1/2 inches, with two double backs for

paper, a landscape lens 2 1/2 inches diameter, stand, etc., costing

about £16. I had prepared- some paper, and on the receipt of my

apparatus August 1, 1853, 1 produced my first picture, which was

tolerably successful. I will describe in detail the process I

adopted : First, to make iodized paper : The method I first used

was to wash over the paper, cut a little larger than the proposed

negative, with a solution of nitrate of silver, 30 grains to the

ounce, and when this was absorbed it was put in a bath of iodide

of potassium, 20 grains to the ounce ; then thoroughly washed to

free it from nitrate of potash and hung up to dry. A better

method which I subsequently adopted was to use a double iodide

of silver and potassium made thus : Dissolve separately in dis-

tilled water 60 grains each of nitrate of silver and iodide of po-

tassium ; mix and allow precipitate to subside ; wash it in several

waters, add 4 ounces distilled water and 600 grains iodide of po-

tassium, or sufficient to redissolve the precipitate. The paper I

found best for negatives was Turner's, made at Chafford Mills,

near Penshurst. This paper, and I believe most English papers,

are sized with gelatine, the foreign papers with starch, and I

attribute the superiority of the former to its containing gelatine.

The paper being cut to the size somewhat larger than the pro-

posed negative, have a board larger than the paper covered with

flannel on one side, on the other side a piece of webbing nailed

on, to put the hand in.

Lay a piece of white blotting paper larger than the negative

paper on the flannel ; on this, the negative paper, pin with silver

pins the four corners to keep the whole firm. Then take a thick

glass tube like a test tube, but open at both ends, and a thick

piece of silver wire longer than the tube, with a hook at one end

and some cotton wool quite clean. Take a piece of the wool, say

about the size of an egg, and with the hook catch the middle of

it and draw it about an inch into the tube. Trim the tuft of

loose fibres, and it is ready for use. It will form a most conveni-

ent brush which has frequently to be used in the process. It

244

was the invention of Mr. Buckle and was known by his name.

Its advantages are obvious. There is nothing to disturb the

chemicals, and a new brush can be made in a moment. Some

used a glass rod and other contrivances, but nothing can be better

than Buckle's brush. I recollect having a brush with Dr. Dia-

mond on this subject in one of the Journals, Pour into a glass

measure a small quantity of the double iodide solution ; 1 ounce

will cover 10 pieces 8 1/2 x 6 1/2" . Saturate the brush and wash over

the paper, beginning at the top, by broad strokes to and fro hori-

zontally, and finally in the contrary direction. Lay aside for a

short time and let the paper absorb the solution ; then place in a

large dish of clean water and change it several times to free it

from iodide of potassium. Several sheets may be put into one

dish, but they must not be allowed to lie close together. The

iodide of silver remains in the paper and colors it a pale prim-

rose color.

My paper generally remained in the water all night, and was

then hung up to dry. Light does not affect it ; on the contrary,

we were in the habit of exposing it to the sun, under glass, for

some hours. I cannot say if this was necessary. Each sheet

should have a pencil mark at the back, because the iodized sur-

face is not easily distinguishable in a yellow light.

The next step is to excite for camera, which must be done in a

yellow light. Cut the iodized paper to the exact size of the holder.

Take the board with a clean piece of blotting paper on it and

pin a piece of the iodized paper by the four corners on it. Make

the two solutions following :

Nitrate of silver _ 50 grains.

Distilled water _ 1 ounce.

Acetic acid 80 drops.

Call this Solution A.

Gallic acid 10 grains.

Distilled water 2 ounces.

Call it Solution B.

Take 2 drachms distilled water, add 6 drops of Solution A, and

then 6 of Solution B. Do not mix the two solutions till one is

diluted with water. This quantity is sufficient for 2 pieces

8 1/2 inches x6 1/2 inches Brush over evenly, leave for half a minute, and blot

off with clean blotting paper ; place in the holder. In backs

intended for 2 pieces of paper, place a piece of red blotting paper

245

between the two, taking care that the sensitive surfaces are next

the glass. The time of exposure, subject of course to amount

of light, was 4 or 5 minutes.

■ To develop picture : Take of Solutions A and B equal parts ;

about 40 drops of each are required for 2 pictures.

Should the negative be visible beyond a pink sky, wash over

first with Solution B. Pin the negative on the board and proceed

to wash over evenly with the brush. When the development is

nearly complete wash over finally with Solution B.

Then wash in three waters and set in a solution of hyposul-

phite of soda, 1 ounce to 20 of water. When free from yellow

iodide, wash in several changes of water to take out hyposul-

phite of silver. It may then be hung up to dry, or at once freed

from size. For this purpose place it in a shallow porcelain dish

and pour boiling water over it. When transparent hang up to

dry, or remove the water by blotting paper. When dry iron

with a box-iron. Hold the iron in the right hand, and in the

left a piece of white wax ; melt the wax with the hot iron and

saturate the negative with it ; remove any superfluity by ironing

it between sheets of blotting paper. It should then be almost

as transparent as glass. The final step is to print from these

negatives.

I had a great objection to albumenized papers and printed my

proofs in manner following : Salt any good paper with a solution

of chloride of ammonium, % a grain to each ounce of water.

When dry, pin a piece on the board and wash over with Buckle's

brush the following solution :

Nitrate of silver 30 or 40 grains.

Distilled water 1 ounce.

When dissolved add solution of ammonia sufficient, after pre-

cipitating oxide, to nearly redissolve precipitate.

Fix in bath % ounce hyposulphite of soda to 20 ounces of

water and tone as usual.

I claim for calotype several advantages : First, for cleanliness

— there is no need for dirty fingers ; next, no necessity to work

in darkness. One or at most two thicknesses of yellow calico are

sufficient during any stage to keep out excess of light so that the

development can be pleasurably watched. I have frequently had

quite a bevy of ladies looking on during the development of my

day';s work. Further, the development can be very much con-

trolled — parts which are slow in making their appearance can be

246

stimulated with a few drops of Solution A, and when it is too

rapid can be retarded by a wash of Solution B.

I had a camera made for pictures 15x12, and the process is as

easily worked as in that I have described. I made compara-

tively few pictures with it ; other engagements prevented my

pursuing it.

I took with me on an excursion 4 pieces of paper sensitized in

two double backs, which I carried in a flannel bag with two

divisions by a strap over the shoulder. In very hot weather I

wrapped the whole in a woolen shawl dipped in a brook and

wrung out to keep it cool. The negatives were generally devel-

oped in the evening by the light of an ordinary candle.

When taken out of the backs the sky is generally of a light

pink color ; if much detail appears it is a sign of over exposure.

As this is a slow process, calm weather is most desirable ; the

best time to insure this is about an hour after sunrise, and in this

way I have been able to take sharp negatives of leaves and corn,

although the exposure was 5 minutes. Calotype and the mod-

ern methods may be compared to traveling in the old time and

to-day ; the former in both cases is, I think, the pleasanter. I

have had a large experience in photography since collodion

drove calotype out of the field — in the exhibition of 1861 and

two journeys to France — but the early days have the mo.st agree-

able reminiscences. In addition to exhibiting my pictures in*

London, Edinburgh, Norwich, Manchester, Cheltenham, etc., I

sent some to Brussels in 1856, for which they awarded me a medal.

I made large quantities of iodized paper for amateurs ; a Mr.

Raven ordered 300 pieces 12x10 to take with him on a conti-

nental trip. Among the workers in calotype at that period were

the following :

Dr. Diamond,

Dr. Percy,

Rev. J. R. Major,

Rev. F. A. S. Marshall,

Rev. T. M. Raven,

Rev. J. Winter,

The Hon. A. S. Kerr,

C. Innes, Edinburgh,

G. Moir, Edinburgh,

A. Rosling,
