Studio Goppo Workshop 2022

Workshop on Colour Gum Dichromate Print:  

19th to 21st Aug 2022


Gum print is a contact printing process in which the image is formed on a coating of sensitized gum containing pigment. Exposure to UV light makes it insoluble in water hence when the exposed paper is developed in water the pigmented shadows remain while the highlights are washed clean.

The gum print process can be made to yield prints of great beauty.  Gum print has a distinctive character of its own. for an overview, one can visit  and here. 

​ Our Approach:

Colour gum print is one of the very few historical colour printing processes. We will discuss and teach how versatile colour gum printing is. We will share the process of making digital negative from your colour digital images either in RGB or CMYK mode. We will share the methods of paper preparation and selection of colours. The workshop will cover and aim to share the knowledge behind the craft of colour gum bichromate printmaking.


Workshop overview :

  1. How to process colour digital images for printing

  2. How to decide on RGB or CYMK negatives

  3. How to make colour digital negative, curve correction etc

  4. How to select and prepare the paper for colour gum print

  5. How to make registration, prepare the chemicals, brush, colours

  6. Exposure time to tonality ratio

  7. Various developing process


Workshop fees: INR 20 K ( 30 hours of training, including all materials, assistance, Breakfast & launch or dinner, tea, and coffee )

New Cyanotype, Gum Print & Vegetable Dye tonning

16th to 18th Aug 2022

Workshop on New Cyanotype, exploring plants for toning and monochrome gum print to add another colour to cyanotype print.  


This workshop is a bit ambitious as well as simple to work with. Looking at the growing interest in cyanotype in south Asia, we decided to offer a workshop on the various blueprint methods. This workshop primarily works with the new Cyanotype process introduced late 20th century. The new cyanotype is much faster to print and provides brilliant blue. We will explore various vegetable dyes, flora and fauna to change the colour blue to black/ brown/ green etc. Along with the new cyanotype and vegetable toning, we will introduce training on Monochrome gum print. We will learn how monochrome gum print can transform the cyanotype's colour or produce a mixed-medium process in multiple colours.


Overview of the workshop:

  1. Learn new cyanotype process

  2. Various details and possibilities of the new cyanotype process

  3. Exploring Santiniketan for locally available flora and fauna that can change the colour of your blue print

  4. How to make monochrome gum print over cyanotype print

  5. How to change or introduce another colour to cyanotype print


Workshop fees: 15K (30 hours of training, including all materials, assistance, dinner, tea, and coffee )

Wet Plate collodion Negative & Salt Print 
12th to 15th Aug 2022



A glass plate is coated with salted collodion and dipped inside a silver nitrate chamber for 5 minutes to make the plate sensitive to light. The plate is exposed inside a plate camera and developed in the darkroom. This is how a negative image is produced on a glass plate. If necessary the negative is then intensified by the various intensification processes to be able to make prints using albumen or salt print process.   


For more details about the process please click here & here

Our Approach:


The wet plate collodion process was the primary method of photography in the mid-19th century. The process was predominant in recording the history of the time. Multiple alchemists/ photographers have contributed a significant amount of knowledge to improve the process. Over the years, this vital method of recording images has been replaced by other more developed methods.  

However, in recent times, we can see a growing interest among contemporary lanes-based artists to work with the wet collodion process. The aesthetic and visuals it produces are incredible and cannot be ignored in this world of saturated digital images.

In this workshop, we will teach the craft of photo-making using the wet collodion method. We will appreciate the aesthetics and visual characteristic it can produce. We will discuss the possibilities it offers. The craft of large format glass plate negative making and editing is the key focus area. The workshop also teaches you how to make the silver chloride-based salt print ((using either gelatine/ albumen or starch as a binder) on paper and tone the image with gold chloride.

Course outline

  1. Making of salted collodion, Developer, Fixer, varnish: using locally available chemicals as per the Indian climatic condition.

  2. Making of glass plate negative, the process of intensification and manual editing

  3. Making of salted paper

  4. Making of salt print and gold toning

  5. Using a wooden plate camera

Workshop fees: 20 K (30 hours of training, including all materials, assistance, Breakfast & launch or dinner, tea, and coffee )
