Cross processing e 6?

However, cross processing can take place in many other forms, such as negative color print film and/or positive color reversal film in a black and white developer. Other interesting effects can be obtained by bleaching colour films processed in black and white chemistry using an hydrochloric acid dichromate mixture or using potassium triodide (KI3) solution. If these bleached films are then re-exposed to light and re-processed in their original colour chemistry, subtle, relatively low contrast, pastel effects are obtained.
