400 OUTDOOR RECREATION 



Experiment. To show the processes of printing, developing, and fixing 

 a picture. 



Materials: Three small glass or enamel trays. One large tray. Printing 

 frame with glass. Film or glass negatives. Azo or Velox paper. De- 

 veloping powders and hypo. A ruby light or dimly lighted room. A 

 strong light for printing. 



Method: Work with some one who is experienced in making pictures at 

 first. Learn from him how to do the various operations. Write 

 a complete report of the processes and the reasons for them as learned 

 from study. Mount a specimen print which you make yourself. 



How to make a picture. In taking a picture, we should 

 bear in mind the following points : (i) We wish to have a 

 pleasing composition. Try to get good balance in your 

 picture. Focus on the principal thing to be photographed.

 will learn to know your own lens and how to use it after 

 you have worked with it for a time. (4) Be sure that you 

 use an unexposed plate or film. Many pictures are spoiled 

 by double exposures. The best way is to write on your 

 plate holder or film each time when you take a picture.

 stantaneous exposure. If you take a snapshot be sure 

 that the image of the object you wish to take is in the 

 finder when you snap the shutter. 



Printing. Boys and girls should learn to print their
