For years we have sold the Dust-Off brand of canned air made by Falcon. These are the familiar blue and white aerosol cans with the black tops and the red extension tubes that are racked up in the ink,  paper, and chemistry section at the back of the shop.I guess they aren't actually aerosols - they are compressed air in there. The cans have traditionally cost $ 25 and last for ages in most applications. Good steady seller.Originally the only use for them I conceived was in printing negatives in an enlarger. The Dust Off can was used to spray over the top surface and under surface of the negative in the holder to blow away dust.The enlarger has been gone for years but the Dust Off remains - because I have found a raft of new photographic uses for it:a. Spray the dust off the platen of the Epson V700 scanner. It's a large glass surface and attracts gunk via static electricity. I wipe it with an anti-stat cloth and then the Dust Off and it is pristine. The negs...

Canon users please draw nigh and give attention. We have a good thing for you.This blog post looked to be difficult for me - I do not use the Canon system cameras and I am somewhat clumsy with modern file storage and transfers. I trembled at the amount of complexity that I feared would be involved.Then I read the instructions and looked at a YouTube advertisement. It turns out that what looked like an elephant in the room was the little one from Walt Disney and I need not have feared looking like a Dumbo. This Canon hub is as easy as to use.Think of it as a 1 Terabyte storage device that you can put files into from Canon cameras or various smartphone devices. It connects to your television to let you store videos or see still files. You fill it up and away you go.Ideally, the connection to your phones and Canon cameras is wirelessly via WiFi or NFC. They realise that some people have older gear so there are ports in for USB connections and you can...

Your normal reaction to a large Spyder may be to reach for a swim fin or flame thrower, but we would like to break you of the habit. Not only will you be a better friend of the environment, but you'll get better pictures as well. Miss Muffett - invite the Spyder Cube to sit down beside you.The grey card is one of the most useful of devices to judge accurate exposure with. No matter how much confidence we have in the software of our camera, there are times when it can be fooled and we need to be able to correct its errors. If we use a grey card we can find the 18% reflectance point that gives our meter the best chance of an even exposure.If we also have access to a pure black tone and a pure white tone in our image we can tell our computer exactly how far to go for the image that it alters.Finally, for the ultimate of contrast control, we look for the ultimate specular highlight and absolute shadow. But frequently in...

You've probably seen the letters " E & OE " at the bottom of a lot of the Camera Electronic advertisements and wondered what they mean. I asked one time and was assured that they stand for " Errors And Omissions Excepted ".It is a sort of a quasi-legal phrase that seeks to stop arguments when the situation goes pear-shaped. We are all human...

The new digital photographer can be forgiven for being confused by any number of aspects of the sport - there seem to be so many to learn.He or she used to be confronted only by which film to use, does the orange needle match the mark on the light meter, and is the Chemist open so that I can drop my film in? Then in two weeks it was should I buy another roll of film or a bag of barley sugar and box of bandaids?Now it is white balances, tonal curves, video frame rates, colour spaces, and all the rest. No wonder they have started putting an " Automatic " setting on new cameras and dedicating a knob or lever to it. The relief for some shooters must be palpable.It is nearly the same for the shooter who wants paper prints of their work. What do they do now that the chemist has gone out of photofinishing and reverted to selling overpriced vitamin supplements and something for the weekend? What are the alternatives with that card full of images?a....

A recent column that dealt with stolen cameras seems to have garnered a great deal of interest - so I've decided to add some thoughts on the matter of further security for photography.The original column mentioned stolen cameras and suggested increased security measures for equipment inside cars. Now it is the turn for the same security inside the home.A. Equipment safety. You may have anywhere from $ 400 to $ 40,000 invested in cameras and lenses. If you put them into camera bags and cases and then put those cases inside the wardrobe your security level is that of the MDF board on that wardrobe. About 3mm of pressed wood pulp. Perfectly adequate to protect your 1980 safari suit against moths but no help if a burglar with a habit breaks in and looks for saleable items.Look up locksmiths and safes. If you have space in your home for the wardrobe, you have room in the wardrobe for a safe or storage cabinet. It doesn't need to be Fort Knox - it just needs to deter the casual criminal. I've...

We've all seen those books in the stands - the yellow and black ones refer to us as dummies and the orange and blue ones are aimed at idiots. In some cases they say they are for complete idiots - a degree of excellence that seems a little disturbing to aim for.I must take a second to say that these books are adopting such a disdainful attitude with the view of correcting our faults. They may sneer at us but they try to teach us - by the end of the book we are probably going to be familiar with the basics of hydraulic engineering or Sanskrit or whatever was printed on the cover. We can even get dummy and idiot books that deal with photography...

Novice computer users have it good. They do not know what they are doing and anything that works is a victory - even if it is occasionally a pyrrhic one. As long as the screen does not go solid blue all is good.Further on, when we get to our digital adolescence and the html hormones start to surge, we get more adventurous. We load our computers with a bazillion files and then try to save them, export them, or back them up somewhere. We would, in many cases, be better backing up an articulated bus through the back streets of Balga. At least when it all went pear-shaped the bus would be wedged into someone's lounge room - not vanished into the aether...
