Color temperature is a term generally used to describe the color of a light source or the maximum white that a monitor can produce. For accurate color matching between an image viewed on a monitor and a print or transparency, the color temperature (white point) of the monitor must be adjusted to match the color temperature of the light used to view the print or transparency.
Color temperatures are normally measured in degrees based on the black body radiation curve which describes the color change of objects when they are heated. Low temperature light sources light incandescent and quartz halogen lamps (around 3000 degrees) are somewhat orange. Standard daylight is around 5500 degrees. A typical uncorrected color monitor is rather blue (around 9300 degrees).

Quiet Super-8 Cameras
The most quiet Super-8 cameras are Nizo Super-8 with four digits in the model number. If you lack a quiet camera, you can have the actors to lip sync and record the scripted soundtrack in studio. Elmo 1012 XLS and some Chinon Super-8 camera are also quiet but Chinons might be less reliable. Louder cameras can still work for scenes that are shot outdoors, as outdoor sounds dissipate quickly. Interior locations make the camera noise to sound louder. Test the loudness of a super-8 camera with old film cartridges.

Oversize objects need to be stored according to their needs. Map cases should be made of chemically stable materials such as anodized aluminum. Wood requires barrier materials and sealing. Boxes should be buffered, lidded and lignin-free such as the Solander boxes, "clamshell" style or "drop-front". Folders are the least pricy storage enclosure. They shouldn't be overcrowded and clearly labeled with waterproof ink to eliminate damages. Melinex encapsulation is a good solution for fragile and frequently handled materials that are not acidic. Mats and folders with polyester film interior covers can also be used. Oversize sheets can be rolled on a lignin-free tube or hanged. Folding and sectioning are not recommendable.

Enclosures should follow preservation standards in order to provide physical and chemical protection for books and artifacts on paper. They should be made of acid-free materials and chemically stable to avoid forming acids over time. Calcium carbonate can be used as an alkaline buffer to neutralize acids.
Molecular traps or sieves can protect against particles of environmental pollutants and byproducts of deterioration that might pass by the buffer. The materials should be stored in durable enclosures with a pH of 7.0 through 8.5 that follow the ANSI standards. Plastics should be used with caution. Always ask the supplier for details regarding the products.

Photographic materials are unstable and frail but their life can be extended if you understand and remove the conditions that can damage them.
The nature of these materials consists of at least two layers: the emulsion layer (particles and dyes) and the "support layer" (paper, plastic, etc.).
Temperature, humidity, light, pollution and contaminants can deteriorate them. You have to avoid the contact of photographic materials with these damaging factors.
The photos needs to be framed properly, stored in plastic envelopes and cleaned using a soft brush. You can also reproduce them and retouch them. It is a good idea to scan photographic prints and transfer film to dvd to provide a digital copy that can be stored away from the originals in case of fire, flood or other disaster.
Scanning Your Personal Collections
Using a few simple steps, you can successfully scan your documents and photos. Don't forget to refer to the scanner's manual as well. Prepare the scanner and the collection by cleaning them. Select the appropriate scanner settings by checking the PPI or DPI, resolution and color tones.
For 4"×6" and 5"X7", 300dpi/ppi is fine. Scan at 400 or 600 dpi for larger ones. Scan slides at around 1900 dpi. Save the image according to the color scheme. Then give descriptive names and organize them nicely.
Create backup copies and store them in various locations. Update the storage medium every five years.
The life of digital storage media is limited so you need to manage digital preservation. It involves three factors: media durability, media usage, storage and handling and media obsolescence. Durability addresses the fact that the reliability of media items varies. Usage, storing and handling refers to the impact of people on the longevity and quality of storage media. Obsolescence focuses on the constant changes in computer technology that can make older forms of storage media unrecognizable and unreadable. You need to organize the important digital content by making copies, using different types of media, storing them in various secure locations, labeling them and create archival copies regularly.
PPI - pixels per inch
PPI is an abbreviation for "pixels per inch" and it belongs to the image category of digitization. PPI is sometimes used interchangeably to the slightly different concept of DPI, which refers to "dots per inch" and might have a distinct meaning in certain situations. But they are often referred to as the same basic concept. PPI is usually used to characterize the capabilities of an imaging device or a digital image when it comes to the resolution. Basically, it describes the proficiency of a device such as a scanner to render the smallest units of information in the structure of an image.
Technical Terms: White Point
The white point of a monitor refers to the color of the brightest white it can generate. If uncorrected, most computer monitors have a white point that is somewhat blue compared to normal daylight or artificial illumination. To achieve an accurate match between images on a monitor and prints, the color temperature of the monitor must be matched to that of the illumination used to view the prints.
How to adjust white point in Photoshop:
The Auto option for Levels and Curves and the Auto Tone command automatically adjust the black point and white point in an image. This clips a portion of the shadows and highlights in each channel and maps the lightest and darkest pixels in each color channel to pure white (level 255) and pure black (level 0). The intermediate pixel values are redistributed proportionately. As a result, using the Auto option or Auto Tone increases the contrast in an image because the pixel values are expanded. Because the Auto option and Auto Tone adjust each color channel individually, it may remove color or introduce color casts.
The Auto option and Auto Tone give good results in certain images with an average distribution of pixel values that need a simple increase in contrast.
By default, the Auto option and the Auto Tone command clip the white and black pixels by 0.1%—that is, it ignores the first 0.1% of either extreme when identifying the lightest and darkest pixels in the image.
How White Point in Photos Works:
While you can auto adjust the white point, in many cameras you can slide the temperature slider and when you like the results you take the picture.

James Cameron and Joel Silver are just a few of the filmmakers who are grateful for 'The Super 8 Book', a guide for using Super 8, which got their start shooting on this film. It was the cheapest one and it was used also by families for events. Super 8 was much easier to use than the regular 8mm and provided a better quality and an automatic exposure system. Amateur filmmaking rose due to the low cost and improved performance of Super 8. Though it's nearly fifty years old, Super 8 is having a comeback now due to its special qualities.

The HSL color space categorizes colors by their hue, saturation, and lightness. As in the HSV color space, Hue corresponds tothe colors around the outside of the color wheel and Saturation refers to the intensity of a color.Varying hue with 100% saturation and 50% lightness. Varying saturation with 0% hue and 50% lightness
The HSL color model allows the color to range from a color that is fully saturated to gray. The HSV goes all the way down to a white, which is not useful to many users of the color model. On the other hand, light can range from white to black in a HSL model (with the desired color in between), while the similar HSV color model can only range from the desired color to black. It is obvious that the HSL color model does indeed offer more freedom
The Hue slider will acually change the color whether its one color that you've targeted or all colors in the Master channel. Use it in conjunction with the colorize check box (bottom right) to achieve almost limitless monochromatic effects, or use it on a targeted color to alter the color temperature. For example, say you have some greenery (perhaps some ivy in the background?) that you want to make more aqua rather than warm and yellow. Make sure you're editing the greens and slide the hue slider to the right slightly. Keep in mind that this will effect all the greens in the image.
Now for the bars at the bottom of the dialog. The color bars at the bottom show your color before (the top color bar) and your color after (the bottom bar). The color inside the middle bracket (which shows up when you are targeting a specific color) is the main color that you will be affecting and the colors inside the outer brackets are used to feather your selection. You can resize any of the brackets to fine tune your selection and narrow down the color that you want to affect.
Transfer VHS tapes to your computer
With a bit of extra time and a cable, you can learn to digitally record analog VHS home movies onto the computer. You'll need a VCR with audio and video output on the back. You'll need a VHS to record from and a computer. An hour video has about 700 MB. An adapter that will connect your computer to the VCR is mandatory. The software will walk you through the process of recording in real-time. Then you can burn your dear VHS tapes to a DVD or keep them on your hard drive if you have enough disk space.

Daytime Exterior Shots
Exteriors are an ally of the Super-8 filmmaker as the cameras are portable and easy to operate. The recommended film stock options are Velvia for open areas and Vision 2, 200 T for areas with buildings casting shadows. Shooting indoors provides the advantage of uninterrupted access and convenient lighting. Minimizing the significance of the background speeds up the production schedule and it focuses the attention on the actors, which enables each actor to boost his career. Super-8 is much more affordable than 16mm. You can transfer the film it to any video format and its look will improve as well.
