maco 4x5 developing - first results

["Joseph O'Neil" <joneil@xxxxxxxxxxxxxx>]

	Have not tried to print them yet, but I shot my first 4 sheets of Maco 820 
last evening, and developed them.  The first two I metered at 100 ISO with 
a Pentax Spotmeter (analog)  and used a B+W #041 filter - it is a deep 
orange & red colour, not quite either red or orange.  The next two I 
metered at 12 ISO and shot through a B+W # 093.
	I developed in Rodinal for 12 min at 1:50 ratio in a Jobo tank on a 
motorized base.  I use this time for my Tri-x shot at 200 ISO (varied by a 
minute or two) so i thought I would try the Maco in this combination.
	The shots fitlered through the 093 filter are way too thin to 
print.  Looks like I need another 3-4 stops, but I will have to experiment.
	The negatives through the 041 filter came out nice however.  A wee bit 
thin for my tastes, compared to the look of my tri-x or HP5 negatives in 
4x5, but not bad.  Problem is I have not printed them yet so they might be 
right on, but I think maybe one extra stop will get them where I personally 
like them.  Again, I have not printed them, but the negatives look a lot 
like Konica 750.
	Next few shots I plan to try through the orange-red filter at 50 ISO 
and  maybe at 25 ISO through a  plain 25A red filter.
	So there you go, if anyone is looking for some guidelines, but take with 
the proverbail grain of salt.  I develop my negatives to match the hardness 
of my water, the enlarger I use, the paper i use, and a thousand other 
variables.  Give me a couple weeks, I'll try and get some shots online, but 
untill then:
Maco 820 plus  orange/red filter at 50 to 100 ISO plus Rodinal 1:50 for 
12min (20C), constant agitation in rotating tube, looks good.
	The #093 fitler - that I'll have to work on.  Any suggestions?
