I have been using one of these for the past eight years in preference to all my other ball heads. It is smoother acting and locks with out creep better Than an any other head that I have used. the double rotator is a blessing as it lets you rotate parallel after setting the ball .it is...

Card recovery software is mostly useful to recover images from a cards that he been reformatted. Reformatting does not delete images or scramble them. It just removes oll the indexing to them . I have done once and it worked just fine but I had to rename the files. It will not recover over...

I have never had a card failure or lost image. So what? All systems and mechanisms have failures How would this survey be able to distinguish between a card failure and a camera system failure. For me at least failures are vanishingly rare, as to be disregarded in any practical sense. That...

How big are these spots, what do they look like. Do they appear to be on the surface. Are they transparent or or solid white. The most common causes are either hard water or undissolved developer or fixer, The cure is the same rewashing in filtered water.

Cruise photographers had limited fresh water and had little choice but use some filtered sea water. But it. Leaves a salt scum on film as it dries. So final washes must be in fresh water. One way and another film photography uses a lot of water. Modern Colour processing and printing machines...

A water bath is good for consistency. Summer or winter, Some times it is preventing the tank heating up some times from cooling down You do not need to have a film or developer in the tank to test temperatures over time. Just fill with water and go though the motions take a reading before you...

Breaking a mercury thermometer on to a silver based film could have interesting results, in theory at least the mercury could form an amalgam with any silver it contacted. Never known it happen though. However mercury makes a mess of gold rings.

For processing black and white consistency is far more important than accuracy anything better than a degree is certainly good enough. Time temperature and dilution and agitation, are all factors important to development. None of them are likely to be exact, what ever that might mean. Errors...

There might be an increase in film use but it is from a very low level. It is still very much a minority interest and even smaller when it comes to professional use. Fortunately it is not an itch that I need to scratch as I have shot and processed thousands of films in my lifetime. I can...

I almost always preferred colour slides to be taken with a warm up filter applied. This was true for most customers as well.

When I was. A photography student in the 50's one of. My fellow students was near completely colour blind. In those days photography was largely reproduced in black and white, and our limited attention for colour was to dye transfer printing and colour slides. This being so, this student...

May be not I have had a cataract done in one eye and not the other, one gives a yellow tint, the other by comparison blue, with both things seem normal that is the brain sorting things out.

Accurate colour is very much a myth. It is certainly true that we can measure and produce wavelengths of light very accurately. However that has only a limited relationship to our perception of colour. We can perceive the colours of a person by artificial light as being the same as we saw them...

When I lived and worked in London in the 50's the tap water would leave a while scum on the film because the water was so hard. Johnson's of hendon sold photographic tap fitting cartridge filters that were fine enough to clear it completely. Even today it is always safest to use filtered water...
