I recently enlarged a 4X5 negative to 11X14 and found that a mid-toned sky had really pronounced and just ugly grain. I was surprised to see this at such a moderate degree of enlargement, and I don't recall running into grain problems before with the same film developer combo (though, I haven't printed too many blank skies this big). I developed the shot in Tmax developer (I use a darkroom and processing facility at a local college, so I have been using their chemicals etc.), using homemade abs tubes for about 8.5 minutes if I recall. Good contrast and exposure. Is this a bad combo? Have I overlooked some developing variable that can accentuate grain? Or is this what I should expect from Tri X and I just haven't noticed it yet? Any other film developer combos to recommend for 4x5 landscapes using tube development. Latitude and tonality had been my big considerations - but maybe grain is also a real issue even in this format. I've only been working w/ 4X5 for under a year now - but I'm still amazed at how good a $150 camera lens combo from ebay can perform! Thanks!
