 In his studio on the third floor of a ,;, nank building in this City A. fystt Yer HYli; Yn;. son or Prot Adison E.. Eerriii ouf , a!e LniversttN is :busily engaged in de- ,xre;'pinS process in photography which u .lseaehcs practicaI stage wilt in his 2fdsment and the judgment of a number "t prominent Yale men, reveiutionize photographic art and Invade the Held of the portrait painters and the water color artists. Young VefriiI claims new dis "orery in color photography that sur strsted all previous results in this diree- tton Nerrill is about g years of age and IS not professor, as some peysons have ueslsnatcd him. He has written much for photography, Yale professors who have any special work in photography always consult him and these professors are ucepS interested in the experiments in c"for Photography on which he is work shR f1fc years ago this enthusiastic pho- qographer began experime nting with the nlnerent methods which several German profeSsors claimed they had discovered ker photographiHs nature In it's varied entorings.
 In none of these experiments could he obtain satisfactory results and. accord ing to the statement Mir Eerrill made
 
 obliged to acknowledge failure in their work. along this line of natural reproduce t,on ta color. Mir. verri1l went on rxper- lmenting along original lines with the result that he turned out the past week half dozen colored photogra aphs taken directly from nature. and these were pre- sented to the Connecticut Academy of Science by his father Prof Eerrill who has taken deep interest in his sons investigations. Some of these pictures were copies of water color paintings of Bermuda fishes in groups. such as the angel fishes. parrot fishes and doucella Another was a Bermuda landscape, :n which tho true blue and green tints of the water were we'll brought out, as well as the soft creamy color of an ancient stone residence at Nottingham and the naturSl gray of the rocks:
 Inventor Tells of Process.
 MT. Ferriil in discussing his discovery, said: Whatever has been done in col "rcd photography las been along me only thing we have today in the color line is the tnree-color half-tone which we see in. msny of the magazine illustrations And tffe transparencies used frequently hy public lecturers Neither of these is. strictly speaking, -colored photography. For instance. in the three-coior half-tone the neSStiNt'is made by exposure through three different screens of the coIors of purple. green, and red. The prints are then made with three colored inks and by the blocking oIt of one color by all- other the uesired cHect IS secured This Is the process used in Ethogra ching and Is pirely mechanical one The colors secured In this way are always very bril- liant and the contrasts more or less strik- thing at all resembling natural tints in this way. even after natural tint is ap- piled to tho whole picture
 The McDonough method. the only oth- CT attempt at reproducing tho colors of nature. Is simply used for lantern slides and t"ansDarencies and has not beer sue ccssful as far as photographs are com ccrned. In exposing plate for a nega- tive of this kind one screen ruled in three colors Is used A positive is then made from this negative, and when this is thrown onto a screen of white. as iu the case of a stcreopticon lecture. and passed /! through q screen ruled in the same three colors as that used in taking the picture 1 tine natural 1oiors are brought out on the | surface only. as in the case of the litho- graph process. very much sttenuated. | Tho intcns" blue of the sky and the equal | strength of the other coIors in the land 1 scape are always noticeable to an audi | rncc which has viewed these coiored pie turcs.
 Pictures Direct from Nature.
 My method is to photograph direct | from nature. develop my plate and print l my negative on photographic paper. | which. after being developed and fixed | scene in all it's minute coorings By 1 my method cau gct the iridcsccnt shades of the seashell the blue of the sky. and , changing lights of a sunset as accurately | or much more so, than can he secured by a water-color artist. The more brilliant colors arc the hardest to accurately re- produce by br method. the delicate shades and the Gradations of color being perfect lY and clearly reached in my finished pic lures.
 At present my method is not available making portraits of life. as the exposure is too long In this. however, 1 have made much progress, for when | first hogan to experiment it required an cx posture of two or three hours tn get the required result. Now. an expo2ure in the bright sunlight. of thirty minutes is an that s required. As yon can see. on only very calm day s il possible to secure am still working to perfect my plan. SO that in time I hope it will he practical for life subjects. To do this I must either use lens of greater rapidty or more hi ghlN senstized plates. The lens which l | use is one which I had made to order, and is a very rapid one, costing me about to he obtained bv working with the plates rather than the lens. The plates now use arc about five times as sensi- tive as the ordinary plates uesd in pho toaraphY. Some idea of this senSitiventss l may he secured when I toll you an incl dent that occurred in taking a picture in cave in Bermuda. In focusing for my picture th"re l had the owner Of the cave hold candle in front of the camera. Just before lighting my fuse. as | was a aholrt to take og the cap. I told the man to step hack. He did not do so quickly enough. and got photograph of him. self ind "andlc, the only light being from the candr itself
 Secret in Emulsion.
 "Of course. usc screen. but al- though this process is not secret one l do not feel called upon at present to desCrihe Ii. or tic development of my rlatf. The secret. however of tho entire process is in the emulsion on. the photo
