File and Image Sizes

I’ve been doing some calculations on how big I might be able to print from a 6×17 negative (or transparency for that matter). 6×17 measure 56mm x 168mm or 2.2 inches x 6.6 inches. I can scan on my Epson V550 at 6400ppi however that would be far too much, also I’m not 100% sure how the quality of the negatives would hold up. The best advice I’ve seen is from Nick Carver, check out this video where he suggests 2400ppi for Epson scanners. https://www.youtube.com/watch?v=qtpmlEeJodw He also has plenty of other great videos of his amazing work in the 6×17 format. Well worth checking out. So scanning 6×17 at 2400ppi will give me a file of 5291 pixels x 15,815 pixels… lots! If the intended print resolution is 300dpi that would give me an image size of 448mm x 1340mm (17.6 inches x 52.7 inches) I also found this handy calculator http://jan.ucc.nau.edu/lrm22/pixels2bytes/calculator.htm which indicates I’ll have a file size of 479Mb when scanned at a bit depth of 48 bit. I believe the calculation is based on CMYK. Of course, if I get some captures that I’m happy with I can always look to getting professional scans done but that’s a while off.

6×17 Photography

Well it finally begins, my journey into the 6×17 film format.

I remember being so inspired the first time I went into a gallery in Southbank (Melbourne, Victoria) and saw the work of Ken Duncan (https://kenduncan.com/).  The big, immersive, colourful prints that so beautifully captured the light and colours of the Australian Landscape.

I’ve always had a passion for the images that I’ve seen created in the 3:1 aspect ratio.

I love getting out in the great outdoors and am an enthusiastic photographer, but how to capture something even remotely close.

I’ve dabbled with a 6×17 pinhole camera, beautifully made (https://realitysosubtle.fr/custom-cameras/realitysosubtle-6×17/) however I really wanted something that would take a sharper image.  Digital stitching is another path I’ve been down, it’s not as easy to visualise a composition nor work with longer exposure times. 

There is something that I like about the challenge of slowing down, framing the composition and waiting for the film to come back from processing.  For instant gratification I’ll still take my digital camera with me (which will probably be my lightmeter!) 

There are dedicated cameras for 617 photography, but they are far too expensive for me to consider.  So, the approach I’m taking is a 4×5 camera with a 617 roll film back.

So I’ve taken the plunge and order this Wista 45D

It will still need a lens and a film holder but I’m on my way…

Stay tuned.
