Infrared – a definition

First of all let’s clarify what infrared is. Most people will immediately think about heat radiation if they hear the word “infrared”, but there is something else hidden from our earth-bound eyes.

Infrared light has a certain wavelength with a very wide range. If we only look at the first part of this range, we won’t be able to see heat radiation, but we will be able to see things our eye normally can’t: “Near-Infrared”. A blue sky will turn dark, leaves that reflect a lot of infrared light will appear white resulting in a very mystical photography. You can create great effects if you combine the result with colour. To do that you would shoot a photo twice, once with an infrared filter and the second time without (more about that later).

IR (short for Infrared) wavelength is longer than that of visible light, therefore we need special filters to block all visible light and to let only pass through a certain range of wavelengths to the camera.

Digital Infrared Photography

Now let’s take a look what is possible. Here are some of the best (subjective of course) digital infrared photos I found at DeviantArt, FlickR, PBase and Blogs.

You have to distinguish between real infrared photos and colour-infrared photos. “Colour-infrared” combines infrared photos with average photos. The first photo for example is a colour-infrared picture, since there is still “real” colour visible.

I want to take some digital infrared photos myself!

If you feel inspired by those photos and if you want to create your own digital infrared photos now, I will list a few things you have to consider.

Not all digital cameras and lenses are made for infrared. You can easily test it yourself by making a photo of a remote control while you turn on the Tv with it. Obviously you will have to shoot the front LED and press some buttons. If you can see a red light on the photo, then your camera might be good enough to take a infrared picture. Keep in mind that you will want a professional SLR camera to make really good photos.

Personally I think it’s worth it to buy a SLR instead of one of those low-quality compact cameras in general. To take infrared photos you will absolutely need a SLR, because the filters I mentioned in the introduction require it.

Before you buy any SLR + lense you should make sure that the combination is good enough to take infrared pictures. Some combinations create hotspots on a photo, which means that you will be able to see a large circle of white light in the middle.

A german forum “http://infrarot-forum.de/” has collected several user experiences. You better check this list before you buy anything.

Should you not have a compatible lense, then try to find a cheap one at ebay:

Where to buy camera lenses?

Amazon has some special deals:

Getting an IR filter

Obviosuly there are many different IR filters. Some let pass more light through than others. This is important for the effect you want to achieve. Infrared radiation has wavelengths between about 750 nm (nanometre) and 1 mm. The more light will be blocked the greater the IR effect. A 750nm filter for example (model name “xxx750″) will not block as much as a 870nm filter (model name “xxx850″).
Some filters are named “R72″ or “R87″, yes there is a zero missing! Those will block light below “720nm” or “870nm”.

For beginners the choice will be easy. Read the table above to mak sure you have a compatible lense and then buy a Hoya R72. This will give you good effects immediately. The more advanced users might want to buy a filter that blocks more visible light. The IR effect will be better, you will see a lot less colours on your photo, but remember this will dramatically increase the exposure time! Did I say that you will need a tripod? Also focusing through an IR filter will not be possible in most cases.

Again try to find a cheap Hoya R72 at ebay if you are starting out:

Taking your first digital IR photo

Well what comes first ? Right, a white balance. You will have to put that infrared filter you bought on your lense and then take a photo of a bright sunlit area of grass. Now do a white balance, but use the photo you have just made instead of taking another. Great! From now on I recommend to use a tripod, because you will have to increase the exposure time. Do a few tests and always increase the exposure time step by step. Hopefully you will at least see something on your photos. If it’s a dark day without much sunlight you will have a hard time to take good photos, because sunlight is very essential for infrared.

Sunny day? Great, take a picture of some trees and you will receive a red photo with white trees. This is it, your first infrared photo!

Of course this is a great location for an infrared shot, but this also shows that you can get great results straight from the beginning.

Digital Photo Editing:

Photo Editing is an important part of infrared photography. Usually you will have to put a lot of work into editing your RAW photos. RAW is the format that is recommended, because other formats compress the photo (e.g. JPEG, TIFF) and you will not be able to do a white balance afterwards for example.

There are plenty of comprehensive IR tutorials out there, but I especially want to recommend you a tutorial from Roie Galitz:

Infrared – the invisible light

Don’t have enough money to buy the equipment? Well, then do some more editing and try to achieve the same effect. Not as good as a real IR photo, but still worth trying before spending $500 or more.

The uber-awesome-incredible Twitter Client:

Blu Twitter Client

Download it here.

It’s Twitter on a whole new level. The client itself is very stylish and has a lot of fun features. A little blue bobble is moving from time to time, when you enter a message a big number is counting down (140 is max) in the background and most importantly you can add certain tweeps to your “favorites”. It’s a waste of time if you would try to unfollow all the people you don’t want to listen to, instead mark all those tweeps who deserve it as your “favorite”.

One of the best twitter clients out there, if not the best. And it is working totally fine on Windows 7!

According to the 2008 State of the Net summary 1 in 7 computer users had major virus problems.

Having a firewall is a necessity today. Supposedly more than 50% of the PC’s connected to the internet are either not or unsufficiently protected. Because there are so many unprotected PC’s many people become a victim of hackers. A very common scenario: If you do not have a firewall a hacker might abuse your PC to attack other people without you even knowing about it. Many people, even advanced users, tend to use the easiest firewall-solution they can get, but is that the best solution too? This is going to be a review of the FREE Vista firewall Comodo. Help to make the internet a safer place and try to contribute to this or tell other people about it.

Download: First of all download Comodo for free over here. The latest version has been released on December 3, 2008.

The firewall has a size of 27.3MB. After double-clicking the .exe file I was immediately surprised by a fresh and nice installer. It told me I had to deinstall the ZoneAlarm firewall first, which is a good thing because two firewalls running the same time would conflict with each other. I continued anyway, with the intention to deactive ZoneAlarm later. 100MB is needed for the installation on your HDD. The Comodo firewall comes together with an Antivirus (recommended install, see below).

Comodo Features

Comodo is checking for modified processes, services, registry keys and takes notice if there is the slightest change!

In simple words it scans for any vulnerabilites on your PC which might be used to establish outgoing connections. This is a feature that the ZoneAlarm firewall does not have, therefore this is a big big plus right here. Bundled with the firewall comes a toolbar and a suggestion to change your search provider. This is of course their way to make money with the FREE firewall, since they probably get a commission from Ask.com. I unchecked all the options, but feel free to try it out.

After installing the firewall a popup window will ask you if you want to scan your system for malware and viruses. Honestly I did not expect that it would find anything, since my AntiVirus is pretty reliable, but it did! In about 1 hour and 50 minutes it scanned 368.000 files and found 6 malicious objects! 1 of those I wasn’t fully aware of, which is great because that is a proof that this is not just another AntiVirus that pretends to be good so that you can feel save. By the way you can always stop the search and then delete the objects.

After restarting my PC the firewall immediately recognized my local network and was asking for access for certain applications. The user interface is very user-friendly and you can check almost everything from active connections to active processes. Comodo also includes a traffic chart.

What I don’t like so far is that you can’t see the applications (which you added to the trusted zone) immediately. You can find them under “Firewall” – “Advanced Settings” – “Network Security Policy”.

null

Also be very careful, this firewall is for advanced users! Some applications may not work if you enabled the Proactive Defense!

Firewall Modes – teach your firewall!

The firewall has different modes to learn more about your computer environment. Go to

a) Firewall -> Advanced -> Firewall Behaviour Settings

b) Defense+ -> Advanced -> Defense+ Settings

Make sure you select “Safe Mode“! This will assure that you can allow/disallow access for every application yourself.

Now every time an application tries to establish a connection it will ask you. Here I am updating the very nice All-in-one IM (instant messenger) solution Trillian:

Actually the firewall is doing a lot more than the average firewall out there, it also tries to make sure that your files will not get modified at all. This is so pro-like!

Comodo’s Firewall also gives “Security Considerations” which are very detailed.

Adding trusted applications

If there is an application that won’t load properly since you installed Comodo, then simply check your log. In my case I would have to click on “651″ or “7″ to find out what went wrong.

Ok, let’s say you want to give access to some applications in advance or Photoshop won’t load properly (that was the case here) then simply open the log or the Windows explorer and write down the path to the file.

Now back to the “Computer Security Policy”

Defense+ -> Advanced -> Computer Security Policy

Click on “Add” -> “Select” -> “From running processes”. Find the process in question and add it, obvious wasn’t it ?

null

Once you added the process to the list, right-click it and click on “Edit”. A new window will open, there simply check “Use a predefined policy” and select “Trusted Application” from the dropdown field.

Voilà! Now Photoshop or any other application will load properly.
If you have any question, feel free to ask.
