RECREATION. 



has been liberally added. That brings up 

 the high lights in a wink and leaves my 

 subject clear glass. That is all there is to 

 it except to print in Velox portrait, keep 

 the whites clean and get a deep black 

 tone.

 can. 



A BUDGET OF QUERIES. 



Please give formula for toning bath for 

 P. O. P. paper, which does not require 

 preliminary washing before toning in gold 

 bath, one by which brown to blue-black 

 tones can be secured. 



How can chemical or light fog be re- 

 moved from plates? 



Give formula for intensifier, which will 

 intensify shadows, etc., before the high 

 lights. 



Please give formula for a good local in- 

 tensifier. 



Can a rapid rectilinear lens be used as 

 a fixed focus lens, either with double com- 

 bination, or single lens, at different dis- 

 tances. 



What camera and lens do you regard as 

 the best? 



Are gelatine prints, toned in single baths, 

 permanent? 



Are developing papers, toned in single 

 baths, permanent? 



J. R. Hoffman, Johnstown, Pa. 



ANSWER. 



A formula for gold toning after fix- 

 ing, appeared several months ago in Rec- 

 reation in an article on that subject by 

 E. W. Newcomb. There is none that re- 

 quires no preliminary washing and gives 

 good results. 



If but trifling, rub with chamois pad, 

 wet with alcohol. If strong, use Farmer's 

 reducer. 



None is known. 



Dab blue water color paint on the back 

 of the negative, where you want local in- 

 tensifier. Pat it gently with forefinger to 

 get it even. 



Yes, if you set it for a certain distance, 

 and then make sure to use it for that dis- 

 tance only. 



The only means of deciding which cam- 

 era is best, is to study the catalogues care- 

 fully and see which has the most features 

 you require. All are the best. 



Gelatine prints properly toned and well 

 washed are permanent, whether single or 

 double bath is used. 



Developing papers are also permanent 

 if properly fixed and washed. — Editor. 



SNAP SHOTS. 

 I often have Velox print out unevenly 

 with negatives that make good solio prints. 

 What would be a cause? 



How is a positive obtained from a posi- 

 tive, as a picture printed in a magazine 

 when the printers have only a picture to 

 work from? 



Are isochromatic and non-halation plates 

 more difficult to develop than the ordinary 

 extra rapid plate? 



Is there any better developer for East- 

 man plates that that put up by the Eastman 

 Company ? 



Will printing Velox for 4 or 5 minutes 

 help the prints when they develop too slow- 

 ly with 3 minutes exposure? 



G. V. Mc, Towanda, Pa. 



ANSWER. 



Perhaps you over expose them and the 

 prints jump up too quickly. Try shorter, 

 exposure and longer development. 



By photographing the picture on a 

 copper plate and then etching; in other 

 words, photo engraving. It is a process 

 far beyond the amateur and of no use to 

 anyone but those who use it commercially. 



Iso plates are extremely sensitive to red 

 light. They must practically be put in 

 the holders in the dark and covered after- 

 ward, while being developed. Backed 

 plates are no more difficult to handle than 

 unbacked, providing you use E. W. N. 

 backing, advertised in this magazine. 



No. 



Of course. Cut one 4x5 slip into 4 

 pieces, expose each a different time on 

 same negative, develop all at once, and you 

 will learn much. — Editor. 



Please tell me what pyro powders, ready 

 mixed, you prefer; also, what plates you 

 recommend, speed considered. 



As per March Recreation, kindly give 

 me formula for toning Velox to a number 

 of colors. 



S. A. Coupal, Lebret, Assa. 



ANSWER. 



Eastman's pyro powders, in glass tubes 

 and Carbutt's, New York, are among the 

 best plates. 



For toning Velox to colors read reply 

 to inquiry of Mr. Wm. T. Perry, in this 

 issue of Recreation, page 157 — Editor. 



I have some film negatives that I pinned 

 up to dry on a hardwood table leaf, and 

 they took the impression of the grain in 

 the wood to such an extent as to show 

 the grain in the print, thereby spoiling 

 them for good clear photos. What can I 

 do to remove this impression from the 

 negatives ? 



P. S. Marsten, Medustic, N. B. 



ANSWER. 



Rub vigorously with alcohol. — Editor
