How safe is expired film?

Image
Using "expired" film All undeveloped films change over time, losing contrast and color balance. This is a gradual chemical reaction, the rate of which is a function primarily of storage conditions.  High storage temperatures accelerate change;  low temperatures slow it;  freezing stops it.  Humidity accelerates it;  dry storage helps minimize it. Most film is sold in retail stores, which do not use refrigeration. For that reason, film factories print "process before" dates on their packages. The practice dates from the end of the 19th century, when air conditioning was unknown and refrigeration was uncommon. The factory "process before" date for film is, typically, two years from the month in which the film was packaged. This is always conservative, because the factory must assume that film on retail shelves is stored relatively warm. The "process before" date of fi...

Updating Exif data in your photographs and images

Geosetter in Windows 7 is good and the best but it cannot do what it is supposed to be able to do, which is to change a large number of files all at once. As far as possible, make changes using geosetter. Geosetter actually uses exiftool and gpsbabel. geosetter will update exiftool for you automatically but it will install it for you only for use by geosetter. Other programs cannot use it. exiftool is a command line tool that is very powerful. It can set all files even within subdirectories. You can search for it in C:\Program Files (x86)\GeoSetter\tools or you can download it. Edit the enviroment variable PATH for user to the path where exiftool resides. Use computer>properties>advanced system properties>environment variables. The difficulty is in finding the names of tags and the values to put into them. The date taken is called datetimeoriginal. The time to enter is YYYY:MM:DDHH:MM:SS+ZZ:ZZ I should use the command exiftool -overwrite_original -datetimeorigi...

Film Resolution: Films will always be sharper than digital

Film Resolution (Pixel Count) © 2008 KenRockwell.com. All rights reserved. Using these links to get to Adorama , Amazon , Ritz , B&H , Calumet , eBay and J&R is what lets me keep adding to this site, thanks! Ken. December 2008 I personally buy from Adorama , Amazon , Ritz , B&H , Calumet and J&R . I can't vouch for ads below.

The best comparison I've seen is ISO 100 film compared to 10MP .   Film With film, the image is continuous in all three dimensions: x, y, and z (intensity). With film, you get the same resolution at color transitions (green/magenta, for instance) as you get for light/dark transitions. With f...
