Hello & greetings from South Australia. I love the use of the sepia colouring effect in photography. At work I deal with many old prints from various photographers of the mid to late 1800's & it is amazing the different tones of sepia colouring. We can now control our choice of tint but I guess when produced in the darkroom in a bygone era this was less consistently obtainable, plus many would have had a colour preference as their trademark print.. What do you think
Since you work with prints from many of the photographers that originally processed using sepia would you mind if I asked this question? As I am quite interested in this effect when I see actual antique photos that used this method I notice a vignette effect. I would like to know if this was an effect that was purposely placed in the photo or if it was part of the process of shooting with a pinhole camera box? And also was there a uniform pink color or did it vary. Some photos are very pink some I see are more brown and again some are more of an orange or salmon color. What exactly is the desired color if I wanted to create a more authentic look when using Photoshop to create this effect?
To make True Black white photo into sepia - o.5 liter water add alum 50gms and boil this water and now try with useless B&W photo to test the solution and dip the print into the alum boiling water and as it turn sepia remove it from boiling water and wait to cool down the print when it cool down wash it in running water now this print of sepia is permanent sepia ! Test this method with test strip and then use it for good print !
