Note while this is a great DIY tutorial that thousands of our readers have used Amazon has many inexpensive Light Tents here that will get you some great results. If youre like me, you dont want to spend money if you can do it yourself and yield the same results. One day I was at my local photography store I saw one of these Pop Up light tents. It consisted of a collapsible white fabric box with a hole in the front and 3 lights used for photographing small objects in photographic studios like the shot of the chocolate reindeer to the left. I was going to purchase it until I saw the 1. No way I am going to spend 1. So I set off and built one of these light tents and it did not come out bad at all. Materials Needed 1. A Box It could be any size you want as long as you can light it I prefer it to be as square as can be. You can find boxes anywhere for free. I got mine from work in which they throw out anyway. GS_Typing_Tutor_Network-102475.gif' alt='Typing Master 7.00 Build 2006' title='Typing Master 7.00 Build 2006' />You can also find boxes in the back of strip malls, grocery stores, appliance stores or basically any place that makes or sells products. Thicker the better Free. Fabric This again could be any type. In my box I used white muslin fabric that is found at your local arts and craft store. Buy enough to cover the entire box. US or 1. 9. 9 a yard People suggested other fabrics like White Nylon and white fleece. If your extremely cheap and have some white under shirts laying around. Cut up the sides to where you have two halves of the shirt. If you use multiple shirts, be sure that the color matches or your end result may not turn out as you like it. Tape I use tape to secure the fabric to the sides of the box. Reason being is that In case you want to try out different fabrics. I use regular masking tape. US A Roll. 4. Glue You can use a Glue Stick 1. US a Stick or spray adhesive 5. US per Can to stick the lining in the box. White Bristol board This will line the inside of the box and will also serve as your back round. X2. I would suggest to buy 2 or 3 sheets as you will be cutting up two to line your box Could be more depending on the size of your box and one for the back round. Bristol board is a heavyweight paper. Thick that is used in drawingart. The name came from where it was originated, Bristol England. If you wanted a different back round you can also pick up different colors. Lights You will need to light this box and this could be the most expensive part of the box unless you already have the lights. In my opinion lighting is the most important part of this box. Without it you will not get the picture you desire. I went to my local hardware store and picked up some Daylight Bulbs. Using regular light bulbs will cast a yellow light and should be avoided. I purchased n vision 9. US. Basically any Full Spectrum light bulbs will do. Also suggest a lighting fixture. If you have a one of those desk work lamps, It will work fine. If you dont I suggest getting a Clamp On Work Light. At my local home depot they only had two kinds, A smaller reflector dish 5 for 5. US or the 1. 0. 5 reflector for 1. US. 7. Miscellaneous Tools Tape ruler, Ruler or any straight edge, scissors and knife. Now that you have the Materials I will show you out to make a light tent step by step. When your done you can take nice clean and crisp product shots. Step By Step Process A Take your box with a tape ruler and marker and measure in 2 from the side of the box marking multiple points with your marker. When your done you will see your border, connect the points using your straight edge to where you should have a nice looking squarerectangle in the middle of the box with a 2 border around it. Leave the top and bottom of the box alone as you will not need to mark it. B Cut out the boxes youve drawn. Repeat that to the sides of the box where you have drawn the boxes. When youre done, cut off the top of the box or remove the flaps on the top of the box. LEAVE THE BOTTOM INTACT C Now take your Bristol board and make lines with your marker for every two inches 1. Then proceed to cut out 1. D Glue the paper strips into the box. Make sure the side with marker goes against the cardboard so it can not be seen. E Take another piece of Bristol board and cut is so the width is the same as the inside of the box and the length is much longer then the box. F Place the long piece of Bristol board into the box to where the piece curves to the bottom. Avoid creasing as it will show up in your photo. Cut off excess paper that is sticking out the top. G Cut your fabric to where it will cover the holes. Then cut a big piece to where it will cover the top of the box. H Tape the fabric to cover the holes in the box except the one that is facing your background. Then tape the top piece on. YOURE DONE Now all you got to do is light the top of the box and start snapping away There are many variations you can do to get the photo you want. If youre having a shadow problem I suggest lighting the other sides of the box. If youre getting vignetting I suggest a lens hood or moving the lens more into the box. Photoshop could be a handy tool also Since my lens and camera are not the cleanest I tend photoshop the dust that is sitting on or in my camera. I also adjust the levels so its brighter. Camera sticking into the box. The Light box in action. Another Result of the above light box.

October, 1. 98. 9Note I have an updated article on LZW posted here. Please check out the new article and tell me what you think. I hope it improves on this post and makes LZW easier to understand. Thanks to Jan Hakenberg for correction of a couple of errorsIn Figure 4, the values for new table entries 2. Thanks to David Littlewood for pointing out the missing line of pseudocde in Figure 6. Thanks to Joe Snyder for pointing out a line where a macro should replace a hard coded constant. Any programmer working on mini or microcomputers in this day and age should have at least some exposure to the concept of data compression. In MS DOS world, programs like ARC, by System Enhancement Associates, and PKZIP, by PKware are ubiquitous. ARC has also been ported to quite a few other machines, running UNIX, CPM, and so on. CPM users have long had SQ and USQ to squeeze and expand programs. Unix users have the COMPRESS and COMPACT utilities. Yet the data compression techniques used in these programs typically only show up in two places file transfers over phone lines, and archival storage. Data compression has an undeserved reputation for being difficult to master, hard to implement, and tough to maintain. In fact, the techniques used in the previously mentioned programs are relatively simple, and can be implemented with standard utilities taking only a few lines of code. This article discusses a good all purpose data compression technique Lempel Ziv Welch, or LZW compression. The routines shown here belong in any programmers toolbox. For example, a program that has a few dozen help screens could easily chop 5. K bytes off by compressing the screens. Or 5. 00. K bytes of software could be distributed to end users on a single 3. K byte floppy disk. Highly redundant database files can be compressed down to 1. Once the tools are available, the applications for compression will show up on a regular basis. LZW Fundamentals. The original Lempel Ziv approach to data compression was first published in in 1. Terry Welchs refinements to the 1. The algorithm is surprisingly simple. In a nutshell, LZW compression replaces strings of characters with single codes. It does not do any analysis of the incoming text. Instead, it just adds every new string of characters it sees to a table of strings. Compression occurs when a single code is output instead of a string of characters. The code that the LZW algorithm outputs can be of any arbitrary length, but it must have more bits in it than a single character. The first 2. 56 codes when using eight bit characters are by default assigned to the standard character set. The remaining codes are assigned to strings as the algorithm proceeds. The sample program runs as shown with 1. This means codes 0 2. Compression. The LZW compression algorithm in its simplest form is shown in Figure 1. A quick examination of the algorithm shows that LZW is always trying to output codes for strings that are already known. And each time a new code is output, a new string is added to the string table. Routine LZWCOMPRESSCODE STRING get input character. WHILE there are still input characters DO    CHARACTER get input character    IF STRINGCHARACTER is in the string table then        STRING STRINGcharacter    ELSE        output the code for STRING        add STRINGCHARACTER to the string table        STRING CHARACTER    END of IFEND of WHILEoutput the code for STRING The Compression Algorithm. Figure 1. A sample string used to demonstrate the algorithm is shown in Figure 2. The input string is a short list of English words separated by the character. Stepping through the start of the algorithm for this string, you can see that the first pass through the loop, a check is performed to see if the string W is in the table. Since it isnt, the code for is output, and the string W is added to the table. Since we have 2. 56 characters already defined for codes 0 2. After the third letter, E, has been read in, the second string code, WE is added to the table, and the code for letter W is output. This continues until in the second word, the characters and W are read in, matching string number 2. In this case, the code 2. The process continues until the string is exhausted and all of the codes have been output. Input String WEDWEWEEWEBWETCharacter Input. Code Output. New code value. New StringW2. 56WEW2. WEDE2. 58.

The sample output for the string is shown in Figure 2 along with the resulting string table. As can be seen, the string table fills up rapidly, since a new string is added to the table each time a code is output. In this highly redundant input, 5 code substitutions were output, along with 7 characters. If we were using 9 bit codes for output, the 1. Of course, this example was carefully chosen to demonstrate code substitution. In real world examples, compression usually doesnt begin until a sizable table has been built, usually after at least one hundred or so bytes have been read in. Decompression. The companion algorithm for compression is the decompression algorithm. It needs to be able to take the stream of codes output from the compression algorithm, and use them to exactly recreate the input stream. One reason for the efficiency of the LZW algorithm is that it does not need to pass the string table to the decompression code. The table can be built exactly as it was during compression, using the input stream as data. This is possible because the compression algorithm always outputs the STRING and CHARACTER components of a code before it uses it in the output stream. This means that the compressed data is not burdened with carrying a large string translation table.

Figure 3. The algorithm is shown in Figure 3. Just like the compression algorithm, it adds a new string to the string table each time it reads in a new code. All it needs to do in addition to that is translate each incoming code into a string and send it to the output. Figure 4 shows the output of the algorithm given the input created by the compression earlier in the article. The important thing to note is that the string table ends up looking exactly like the table built up during compression. The output string is identical to the input string from the compression algorithm. Note that the first 2. Input Codes W E D 2. E 2. 60 2. 61 2. 57 B 2. TInputNEWCODEOLDCODESTRINGOutput.

Unfortunately, the nice simple decompression algorithm shown in Figure 4 is just a little too simple. There is a single exception case in the LZW compression algorithm that causes some trouble to the decompression side.
