Large Format Friday with Matt presents, Funky Large Format Sizes! Did you know there is more to LF than just 4x5 and 8x10? Sure you did, if you follow Ag+ Process on Twitter. Lots of people doing 6x17, 5x7 and other formats. Matt lists an extensive list of LF sizes including the standard plate sizes.
A standard plate is 8.5 x 6.5 inches. From which a number of different sizes can be cut. Check out the video for a full list.
Beware of old wood holders from before the war, the First World War! They may not conform to modern standards. Same for cameras from the earlier era, they may require matching holders, modern holders may not work. Get the low down from Matt!
Bonus: Matt makes a kallitype of a plate sent to him from Edinburgh. Check it!
Enjoy!
