By using rehalogenation techniques with Kodak Ektacolor paper, contrasts of nearly twice that produced by CP-5 processing were obtained. A metol-hydroquinone developer was used to produce a silver image which was rehaligenated and then developed in CP-5 developer to produce the colored image. By adding a restrainer to the MQ developer and then increasing development times, it was possible to produce a range of contrasts. Only slight changes in contrast were obtained by varying the MQ concentration. pH and development times at normal restrainer content. By reducing the color redevelopment time it was possible to reduce the contrast slightly.
