TMY EI 1600

This is a photo of my niece, the aptly named, Bella, by my son, Leaf. Leaf was shooting TMY @ EI 1600, in roomlight, with my Minolta XD-11 w/58mm f1.2, handheld. The film developed for about an hour, or so, while I did some other work. I think this combination shows a lot of promise for low light work.

Film: TMY
EI: 1600
Dilution: 1:10
Time: 60:00-75:00
Temp: 70F

GSD-10 mixing instructions

To make GSD-10 you'll need a 1 liter mixing container, the constituent chemicals, and standard lab safety equipment, including; dust mask or respirator, lab glasses and gloves. Work in a well ventilated area.

GSD-10 is made up acording to standard lab practices. Start by adding 750ml of distilled water to your mixing container. Add with stirring, the constituent chemicals in the order they appear in the formula, and be sure each chemical is completely dissolved before adding the next. When all of the chemicals have been dissolved, top up to 1 liter with distilled water. Your concentrated stock solution is now ready to use. Dilute 1:10* to make a working solution.

* Dilution ratios are written in the form X:Y. X = stock solution, and Y = total solution volume. To make a 1:10 dilution, simply divide the total volume by 10 to find the correct volume of stock solution. V/10=VSS (volume divided by ten equals volume of stock solution)


To make 1 liter- 1000/10=100ml stock solution

To make 300ml- 300/10=30ml stock solution

GSD-10 is formulated specifically for slow, designer grain films like Kodak Tmax 100, Fuji Acros 100, and Ilford Delta 100, but produces excellent results with a wide range of films. GSD-10 exploits the unique characteristics of the developing agent, glycin to permit reduced agitation, and even stand development of state of the art, thin emulsion films, without streaking, mottling, or other development defects. GSD-10 produces negatives of excellent gradation, high acutance, extremely fine grain, and true speed increases of up to a full stop with designer grain films, whether developed for low contrast scenes, or high contrast scenes (expansion or contraction development). GSD-10 produces virtually no fog, even when developing to extremely high contrast and density ranges, which makes it as ideal for alternative/UV process printers as it is for 35mm and MF shooters. If you’ve struggled to obtain the maximum image quality potential of the new generation of films, GSD-10 will be a revelation.

Using GSD-10

GSD-10 is formulated specifically for slow, designer grain films, but produces excellent results with films ranging from slow document- type and ortho films, to IR and super-fast films. GSD-10 is a true acutance developer, and as such, very responsive to agitation as a development control. Unlike most true acutance developers, GSD-10 is compatible with rotary processing, but forfeits much of the increased speed, compensation and adjacency effects that reduced agitation encourages. Use 1:5 dilution for rotary processing with minimum solution volumes. Any agitation pattern from rotary to stand is practical, and will produce excellent results with the appropriate compensation.

Development Times for 1:10 dilution

TMX EI 200- 24:00/70F/*stand

Acros EI 200- 28:00/70F/*stand

FP4+ EI 160- 24:00/70F/*stand

TMY EI 800- 22:00/70F/ #1/3:00

* Continuous agitation for first minute, then stand for remainder

# Continuous agitation for first minute, then one inversion every 3:00
