How to Overcome the Problem of Converging Verticals

Converging Verticals

When taking photos of structures one of the challenges that confronts professional photographers is that of Converging Verticals?

Converging Verticals is a term utilized to describe the impact in images when 2 parallel lines in an image (such as the two sides of a building) appear to get closer (converge)- as if they are leaning in towards one another at the top (as in the picture to the left which is of the Rialto towers in Melbourne- towers that do not get narrower towards the top up until the last few floorings).

The result is most obvious when you angle your camera up when taking a picture of a high structure in an effort to fit all of it in. It’s particularly obvious when utilizing a wide angle lens.

What should a photographer do about converging verticals?

Professional photographers have a number of alternatives available to them.

Improve it – as with all types of distortions in photography- one alternative is to improve it and utilize the Converging Verticals to attain a more remarkable image. You can enhance the assembling lines, however, getting closer to the structure, angling your video camera even more and by using wider angle lenses.

Reduce it – if you desire to avoid the converging verticals in electronic camera you will most likely need to move further back from the structure that you’re photographing. This will mean you will probably get more of the foreground in your end image- but you can always crop this later on. Another method to get more parallel to the building is to take the shot from higher up.

Correct it – if you are not able to alter the point of view that you are shooting from and just end up with assembling lines in your shots another option is to do some post production editing. Most image modifying software will have some way of doing this. For example, in Photoshop Elements there’s a ‘Transform- Viewpoint’ option in the ‘Image’ menu. This is how the image to the right had its converging verticals corrected.

Modification Lenses – finally, if you have a budget plan and will be taking a great deal of architectural images you may like to invest in a unique lens that has the capability to correct converging verticals. These Viewpoint Control/Tilt Shift lenses are able to move the lens axis (or optical centre) to make up for the distortion. Such lenses are not inexpensive – so unless you’re going to be getting seriously into the photography of buildings you may wish to utilize one of the other choices mentioned above to repair the problem of converging verticals.

How to remove mouldy odour from cameras and lenses?

How to remove mouldy odour from cameras and lenses?

I recently bought a new old lens for one of my cameras on eBay. Everything is fine so far. But I don’t like that the lens has a stinking musty smell. Here you can quickly help yourself with a simple trick.

I like old analogue cameras. Every now and then I look at eBay, because these devices are now often sold there at a low price. Recently I have decided to buy a wide-angle lens for my Kiev medium format camera. The lens was apparently perfectly fine too – apparently. Because it actually had a mouldy smell! This was due to the bag in which it was. Unfortunately, this must have been lying in a damp cellar for too long. I didn’t want to do anything with it, so I threw away the bag with the strong musty smell.  The smell of mold had also spread to the lens. But here you can easily help yourself.

Yes, you can easily get out the musty smell with coffee!

So I first looked for a plastic box in the kitchen that my lens would fit. I put this in there. Next, I added some instant coffee. I closed the lid and put the can and its contents down for 24 hours. After this time I opened the can and the musty smell is almost gone! The coffee had so to speak soaked up the smell of mold. The lens now smelled slightly of the instant coffee. But this quickly evaporated.

With this simple trick, it is possible to drive out the notorious musty smell from smaller objects (that have been stored incorrectly or damp). With larger objects (e.g. items of clothing) you would have to take a larger bag like a garbage bag and sprinkle a whole pack of coffee into it. The container must be closed, however – especially when working with instant coffee. Because instant coffee tends to get lumpy and sticky with a constant supply of air! You don’t want it to stick to the objects with the musty smell or leave stains.

Clean your photography equipment with some cheap perfume or aftershave

Attention! Do not pour any liquid directly on your photography equipment, because it may cause internal damage, fungus, electric hazard, etc.!

Put few drops of cheap perfume or aftershave on a microfiber cloth and wipe your equipment carefully. You can use ear buds in places that you can’t access. For inexpensive dirty equipment I often use toothbrush. Let your equipment dry. Don’t put it into a bag yet, but also don’t let it uncovered for days on a direct sunlight because it can collect dust and direct sunlight can damage your sensitive  and expansive device. Also, it can get easily scratched or damaged if you forget it on the table or on the top of your kitchen. Wait for an hour after cleaning and place it in a bag or case, if you don’t use them. It is recommended to have a few small bags of Silica gels silicon dioxide that is absorbing moisture in your camera bag. Do not keep your equipment in rooms where the humidity is high. Keep your room at a normal humidity. You can use room dehumidifier to prevent you cameras and lenses. Yet, for your own health is also important. So find the balance (If your house is above 50% humidity then a dehumidifier is needed. However, if humidity levels are below 30%, a humidifier is needed).  

Prevention – Keep your cameras and lenses dry in bad weather

  • Use umbrella
  • Waterproof camera covers
  • Use lens hoods
  • Change lenses under cover
  • Wear waterproof clothing
