Tweedelige filmontwikkelaar (2x 500ml), 50-65 liter working solution voor het ontwikkelen van 150-225 films. 

Tanol Speed generates higher film speeds or shorter development times than Tanol. The stain is yellowish green and with some films the density of the base fog can be higher than usual. 
This developer is suitable for most films between 25 and 400ASA. In most cases the nominal film speed according to ISO can be either reached or surpassed. 
Films that have not been listed are not suitable for this developer. All major brands have been tested. If your preferred film is not in the list, you can spare yourself the trouble of making your own test series. 
As yet, there is no knowledge about the shelf life of the stock solutions after opening. However, there isn't any significant change towards Tanol.

Film speed:
Using the recommended settings, if you make a reading with a colour-blind densitometer you get a silver density of 0.12logD or more for zone I. In the lower zones the total density (silver+stain) is only slightly higher than measured with a black and white densitometer. In the highlights the cumulative density is much higher. If you make your own evaluation with a black and white densitometer and you use VC paper, you may reach the nominal values of the zone system, but you must not exceed them. When using graded paper the curve (without the stain) has to be made flatter by shortening the development time.

The standard dilution is 1+1+100. To reach a higher film speed, use an alternative dilution from our data sheet.
On Tmax film with a dilution of 1+1+130 you gain 1°DIN in film speed. On Rollei Retro100 and Ilford FP4 you can double the nominal film speed by extending development times. In contrast to conventional push development by means of underexposure and overdevelopment, the curve is not steeper but bellied up from the shadows to the mid tones. This is a real gain in film speed without blocking the highlights. On some films this gain of up to one stop comes with an increase of the base fog.
This developer is not suitable for high speed films like Delta 3200. For films that have a tendency to develop a dense base fog (Tri-X, Rollei Retros and IR) Finol is the better choice.
