I blew some air from my mouth on my digital camera lens to moisten it so I could wipe off the oil smears from the camera lens with a cotton swab...then I thought if it would have affected the protective coating of my camera, is it my doubt or the presence of condensed water on camera lens for a few seconds or wiping with cotton swab afterwards could have damaged its protective coating?


Answer
in short, no.

the protective coating is pretty tough, and even without the coating there the lens is going to work fine.

Shoeflower


i just removed a sticker from my camera lens but the adhesive marks from the sticker doesn't go away.. how to remove it without scratching the lens? also hw to remove glue marks from glass surfaces?
sorry i don't have alcohol at home.. suggest an alternative!



Answer
rubbing alcohol for both of your questions.
It is gentle on the lens and the glass, and it will remove all left over residue.
wet a soft cloth with rubbing alcohol and wipe it a couple times!

it costs like 50 cents at the dollar store

What would I need to do or get to shoot videos at night with a Canon DSLR?

best canon 28mm lens image

I have a Canon Rebel T3I camera that I intend to use to shoot some videos in the dark.
For example, I'd like to shoot some videos within the interiors of cars at night while maintaining the visibility on the passengers.
There will be no lights on in the car, and there probably won't be any around the car on the outside?
Will I have to get one of those LED lights that strap on the camera?



Answer
Look around the web for small LED panel lights that mount to your hot shoe. That would be the simplest way to add some light. For a more natural look, so it doesn't look like your passengers are being hit with a camera light, you might experiment with some small LED lights placed at the feet of each person, right on the floor. Or some soft LED lights near the dash to make it look like it's from the illuminated dash cluster.

try white light, maybe some warmer looking colored light for a more interesting look. Expect noise in the video. As the camera needs a higher ISO setting, noise will and can get pretty bad. Make sure you do a custom white balance (check your manual) before you shoot because you won't be able to fix funky color after the fact like you can with a still RAW photo.

Next up, you need a fast, fast lens (large aperture) the cheapest, and most common lens with a large aperture is the 50mm f/1.8. It's a sweet lens for defocused backgrounds, and low light/night work.

for inside a car and other tight spaces, the 50mm won't work too well because it's not a wide angle lens. The 50mm will be fantastic for walking around the streets at night, people in a restaurant at a candle lit table, people near neon signs etc.

For tight spaces, a wider prime lens like a 28mm f/2.8 (non USM) isn't too expensive, same for the 35mm f/2 although, that might not be wide enough. If you want a faster lens, like a 28mm f/1.8 it's expensive, the price of a cheap dSLR, and the prices are even more than that for better wide angle primes. I don't even list the wider angle prime lenses, the prices are very, very high.

For the future, when you want to do this kind of work for still photos and video, you need the best image sensor for high ISO performance within your budget. In the same price range of your Canon, better choices are Nikon's D5100 and Sony's A580. If you should buy another dSLR type camera in the future, and want to do shoots like these, come back here, ask about the best dSLR and mention it's for night work, you'll get pointed in the right direction. good luck.
