How to create nice looking calendar with your photos
Christmas presents for photographers
Take a look at article for winter presents for photographers.
Other than those, here are some new ideas, that might be good if you have some photographer around you and don't know what to buy to that photo geek ![]()
Here are few things that are always usefull.
- additional portable and safe storage for photos,
- monitor calibrator (like Spyder 3 Elite),
- 18% Percent Neutral Gray Grey Card,
- Bamboo Black Tablet with Pen, Mouse & Graphics Software,
and why not a Professional Tabletop Photo Studio,
or Light Tent Studio with 2 Lights
And, don't forget about books. Photography books are great for present. There are various levels of difficulty and also an amazing number of topics covered at Amazons store of books for photographers.
Just take a look at photo section of amazon and you will surelly find something for your friend - being that photo backpack, Compact Flash card (memory is never enough) or something small like nice photo album
On the other hand, you can take a look at some other, but still related presents. Like GPS for a travel photographer ![]()

UV filters
They were more important years ago, but their usage is still useful today.
First, little simplified psychics.
The lights we see is from one specific range of possible wavelengths (light is electromagnetic wave). The shorter the wave length, light is more bluish, the longer - it is more reddish. When the length of the wave gets too short for our eyes to see it, we call that light an ultraviolet light, or UV light. Just because we don't see it, it does not mean that it can't be detected by some instruments. And here is where our problem occurs.
The UV lights and visible light both hit exposure sensors. So, actually, the sensor receives more signal, than we see (because UV is invisible to our eyes, but not to our camera sensor). Recorded UV light makes resulting image to appear brighter and with lower contrast than we see it.
Years ago UV filters were important because film records UV light very well.
The sensor is still sensitive to ultraviolets but not as much. In addition to that, all new lenses have special coatings which filter that unwated part of the light.
You might ask: so, why are there so many UV filters on market today?
The most common reason for mounting UV filter on your lens today is protection. If you are photographing on a field (lots of dust) or at any location where there is possibility that your expensive shiny new lens might be damaged - UV filter is here to help. It might be damaged, but who cares - it's price is like .. hundred dollars, but the price of the lens can be in thousands of dollars.
Theory says that anything that you put between sensor and the object will degrade image quality and probably improve possibility for flare. Same applies to any filter. Degradation is really small and with good filter actually non-existent.
Should you use UV filter or not?
It is a personal decision one has to make. I will tell you mine.
On a location (example when shooting off road rally) - you can bet that my UV filter will be on my lens.
When I am shooting for stock in controlled environment, I usually do the work without them.

Digital picture frames
As digital photography is coming more and more popular, amateur photographers all over the world are making less and less printed photographs. Some of you also have the same 'problem'. You have hundreds of photos and none printed.
One solution would be to select some of your photos and print them. I suggest you to do that.
The other solution is still kind of new, so you might not have heard about it.
Digital picture frame is similar to any picture frame you have seen. The difference is that it has memory and LCD screen. You transfer your photo (usually via USB), and it shows the photo on screen. There are many manufacturers, some are unknows some are big brands like Kodak or Phillips.
There are some advantages and also disadvantages in this approach.
Bad things first: actually the only bad thing about this is its price. Usually not too expensive but more expensive than regular print of few photos.
The advatages:
- resolution needed for great results is smaller then when you want to print the photo - this is usefull when you crop the picture a lot, or want big print.
- you can see it in the dark, too.
- at the moment when you decide that you want other photo, you just transfer another one - and its done
- it looks sexy
In case you don't know which digital photo frame to choose, check this review at coolest gadgets.
