Krispy Kareem posted:I had a question about the last picture. I've noticed my backgrounds appear to swirl when blurred. Is there any particular reason for this? Is that just the 'bokeh' caused by the leaf shutter? No, it's just a characteristic of the lens design. Some have neutral bokeh, where the background is just blurred, others tend to have wilder bokeh or more intense bokeh near the corners (probably curvature of field?). It's a noted characteristic of triplet lenses in particular.

Krispy Kareem posted:
The reason for the swirly bokeh is a lens aberration called coma. Coma causes point lights, especially in the corners of the frame to take on a "comet trail" shape. This trail follows the convex/concave flow of the lens glass. (Wikipedia here.) I'm assuming your Yashica's lens is a Tessar (4 elements in 3 groups) design, which is relatively well corrected for coma, but can be still visible at wider apertures. Usually when shooting night shots you shoot f/8-f/11 anyway so that's why you usually don't see the "comet trails" there. (Unless you are a horrible sperg or K-rock) If you want even swirlier bokeh, go for a Cooke triplet or a derivative thereof. It has less degrees of freedom (air to glass surfaces) and is thus less corrected for color and coma.

So this week I had my 5dmkii stolen, and since I had been looking for a reason to invest in MF anyhow, I now find myself the proud owner of two new cameras. While waiting for my insurance claim (  ), I find myself in a bit of a quandry. Both are Zenza Bronicas obtained at obscenely low prices. One is an ETRS with a 200mm Zenzanon F/4.5, split focus finder, 120 back, and speedgrip. The other is a GS-1 body with no accouterments. The ETRS is practically mint as well as the accessories. Apparently it was a backup given away by a struggling photog to pay off a debt, and was practically never used. The GS-1 I'm picking up on Monday and is supposedly fully functioning, but has some minor cosmetic wear and tear. The question is whether I keep the GS-1. Seeing as how they are two different systems, and the GS-1 has a limited lens and accessory selection that is also relatively rare and expensive, I find it myself struggling to justify keeping it. I'm no balla dentist. Eventually, I want the option of shooting 6x7, but I'm wondering if I should sell it for a healthy profit and go after a Pentax 6x7 or an RB67 instead. I've shot with an ETRS in the past, but have no clue about the GS-1 system's image or build quality aside from what I've read on some photo forums. Anyone who's used the GS-1 and feels like convincing my to keep it, by all means try. If not, I might just try to offload it in the gear for sale thread

I usually price check against KEH and then drop it a bit from there since they offer 6 month warranties on all their used gear. I would get a picture with your username in it before you start thinking about numbers lest buttons be pushed.

I just sold my 67 kit for $450 locally. You could probably get more piecing it out on ebay but it costs nothing to toss it Craigslist and drop the price later if it doesn't sell.

I tried shooting some expired RA-4 paper in the homemade 8x10, managed to get some sharp images, but they REALLY lacked colour: Next time I'll use some loose RA-4 printing filters in front of the lens, as the paper negatives were really red, so I'll need to add lots of magenta and yellow. And the paper was developed in a Rollei digibase RA-4 kit at room temperature.

Contact printing/paper negs make me tempted to cobble together a DIY 8x10, and my Nikkor-M 300 would make a decent normal lens for it... Here's some scrub-tier LF - scanned 4x5 negatives.

I had another crack at colour paper, this time finding stuff in the lounge room to shoot. This was at night under room lighting, the negatives were very magenta, with little colour saturation again, even with some filtering. I'll have to go harder next time: And here's a crop, surprised with the detail:

Wouldn't color paper not have an even color response because it's made to work with color negatives that have that orange base? Anyway, the colors may not be right, but you're getting cool results.

The lenses are sharp as a tack, and the camera system is extremely well suited to all situations, although its size may make it a little unwieldy for some to shoot street with (I don't find it a big deal, it's well made to the extent of being tanklike, a bit bulky and a little heavy, but it's not so hard to hand hold). The shortcomings of the camera are the mirror lockup system which can be irritating, but is fairly intuitive, and the price of the accessories such as the adjustable viewfinder (which makes portrait orientation much less irritating), speedgrip etc in working order. The 110mm Macro, 150mm, and 65mm lenses are all obtainable for not too high an investment.

I figured I'd get more of a colour response than I'm seeing right now, as the paper should be responsive to most of the colour spectrum. But I'm really liking that I'm getting the unpredictable results, I'll try some daytime portraits with it next. I've still got to get an 8x10 dipping tank so I can move up to the big tintypes.

What are the exposure times like with the paper? Have you tried adjusting them significantly? (I assume they are quite long, going by the sensitivity B&W paper typically has.) Maybe try lighting the scene with a series of flash fires, see if that gives a better colour rendition. Also see if you can do something to reduce the natural contrast of the scene, the colours might be getting washed out by the underexposure in the darker areas or something. Aren't RA4 papers typically rather high contrast from the beginning, since C41 film tends to have somewhat low contrast?

nielsm posted:What are the exposure times like with the paper? Have you tried adjusting them significantly? The iso of the paper is about 12, compared to black and white, which is about 3. I've played a little with the exposures a bit outside, and didn't really see much change in the colour palate. PE at APUG posted:It is Tungsten balanced with high UV and IR sensitivity so you will need a good UV filter. The Blue is about ISO 100, the Red is about ISO 25. So it looks like the paper could be really flexible, making 8x10 IR and UV images could be pretty fun.

 2013-673 by Tom Rintjema, on Flickr I'm working out the bugs with shifting a sensor around to cover a larger format. This is about 10cm wide. I used a magnifying glass for a lens and stitched all the bits together. The lens stayed in position and didn't move. I just slid a sensor around the film plane.
