You need to guess an approximate time, so in this case I would consider adding about 15% to the development time for ISO 100. Maybe 11-12 minutes. There is no firm answer for push processing times unless you have tested in advance. You can use the Push Processing guide which can be accessed from the...

Hi Keith,

Our policy is not to publish any speculation, so apart from our stated intention to pursue the release of film developer(s) sometime in 2009, I cannot say anything further at this point.

At the moment we do not have distribution outside of North America. We can ship Silvergrain worldwide, but the US Postal Service no longer offers any surface or inexpensive parcel services, so the cost of shipping is extremely high. We are hoping to bring the Silvergrain products into Europe sometim...

These points of view are not necessarily unreconcilable. While from a technical perspective there is only one "correct" negative, the zone system offers the ability to exercise control of a negative through a combination of understanding the contrast of a scene and manipulating exposure and developm...

Its definitely worth trying Farmer's Reducer, although you should be sure to use it in its subtractive form which is applicable to general fogging. Any Farmer's Reducer kit can be used as either a proportional or subtractive reducer depending on how you mix it, and instructions should be included. I...

Its very hard to say what has happened, but it might be that your film was fogged during loading or development. The other possibility is that your film hasn't been fixed properly. If the film is fogged, you can try using Farmer's Reducer on the negatives, or if it hasn't been properly fixed, you ca...

Hi Bill, There is full information about APX 25 in the Massive Dev Chart, but it is listed in the Unlisted Data section. Although there are some discontinued films which are shown in the main chart, once a film has been out of general circulation for a few years, I routinely remove it and place it i...

No, that isn't going to be the case. The Kentmere chemicals are made specifically for the North American market, and are simply an alternative to the Kodak products where availability and cost might be an issue in different US States. Ilford has its own full line of processing chemistry which will c...

The results should be identical. The Kentmere chemicals are designed to replicate the Kodak products, so any differences would be academic.

APX 25 has been out of production for some time now, and I've had several people asking about alternatives. While its true that modern medium speed films offer great quality, there are still some slow speed films worth looking at for their different characteristics. Here is a brief analysis which is...

1lb of Sodium Carbonate Monohydrate = 0.855 lbs of Sodium Carbonate Anhydrous.

If you convert the quantity based on this figure, the formula should work identically.

Robert, I feel it is necessary to defend the reputation of this film because you have been suggesting that there is something wrong with it. In fact, you continue to suggest this by saying that you doubt you are the only one who has had or will have a problem. Unfortunately, this is a common problem...

I'd like to clarify this thread so that people understand that there is no problem with the film. It now seems as if the issue is related to sharpening in your scanner. I just want to assure all other users of the product that no similar scanning problems have been reported, and we have had many peo...

I have personally developed many rolls of film from the identical batch to the one we sell on the web site and there is no hint of a problem. Additionally, many other users have been supplied with film from this batch - we are talking about thousands of people - and no one has reported a problem. Of...
