LZW is the same compression scheme used in GIF files. It certainly works best on 8 bit files, but more importantly, it is optimized for images with solid color fields. The same holds true for the...

LZW (Lempel-Ziv-Welch) is indeed a lossless compression scheme. It is quite old, having been used since the early 80's. I would assume you are working with TIFF files if LZW is being presented as...

B&H sells replacement Omega dichroic filters. They're around $40-60 each.

Cyan,
Magenta,
Yellow.

You didn't misread it, I was mistaken. When I went back and looked at my notes, I apparently hadn't changed the aperture between those prints. I guess I just failed to clarify that. I made 4...

I shot my first 35mm film when I was about 12 (in 1992). I didn't do much photography again until I was in college, when I picked up a used Nikon N80. I worked at a party photo shop for a few...

I use 100-150mL of chems in mine. I use it for both negs and prints. I went the epoxy route and have a grid of bumps, which lifts the print up a bit making the fins a bit more problematic. I may...

There's definitely some gunk on the diffuser of the mixing chamber. I think it's some of the remnants of the old hardened foam seals that I replaced. I find it a bit odd that the spots changed...

It might be useful to compare to the previous print. This print is from the same negative, but the exposure time was a bit shorter. The streak was from the Orbital tank and I fixed that by doing a...

Here's a quick scan of the print with the spots. The spots are all around the upper left corner of the print.
...

I'll have to go through my notes to see what I've done differently. There was at least a month between my first negs and the ones that have this problem.

I'm not worried about water usage, as I'm...

I haven't been able to find these spots on the negative, but I'll definitely double check. I'm not very good at evaluating negatives yet. I may toss the negative on my scanner to have a look at it....

I have been learning to develop my 4x5 negs and have run into a bit of trouble. My first few negatives came out well (even if the shots weren't exactly art), but more recently my negatives have had...

I'm having a bit of trouble with printing 8x10s from my 4x5 negatives. I'm getting a better feel for my exposure and development, but I'm noticing some flaws on the prints. I was having trouble...

My Crown Graphic may not have full movements, but the rudimentary movements are plenty for the kind of photography I'm interested in. It may not be a fancy new wooden field camera, but I find it...

I looked into wireless USB a bit and it might be exactly what you need. You plug the dongle into the USB port on your computer and set up the wireless hub wherever you want. It should work with...

Wireless printing is quite easy. You can buy a wireless print server (probably 802.11b) with a couple of USB plugs for $50-100 that works quite well. I used one for a couple of years and the newer...

I think I can jury rig the lens cone to hold my lens properly with a little bit of effort. As far as the negative carrier and thumbscrews go, Heroique just happens to be selling the negative carrier...

The negative carrier I got is this one:

Here's the link to the cone: ...

Ok, I guess I'm missing the thumbscrews that hold the cone in place. I'm sure I can find something to improvise if I can't find the proper ones.

The lens cone doesn't seem to have screw holes for...

I have a D2 enlarger with a Chromega D Dichroic II head. I've managed to scrape together all of the major parts that I need. I have the 2-3/4" lens cone and a 135mm Beslar enlarging lens. The cyan...

I just built and used a shutter tester of this sort. I was able to measure the 1/400 speed on my graphex shutter (which apparently a full stop slow, c'est la vie). With a bit of improvement to the...

I bought a Chromega D II head on ebay and it turned out the guy was local. He threw in the rest of the D2 it was on just to get it out of his garage. (He was stepping down to a smaller enlarger as...

Just make sure you can tell the difference between the glass of whisky and the developer! :D

Film Depot in Richardson has a Paterson Orbital with the manual base for sale. I picked up the other one they had and the motor base a couple weeks back. The one they have is missing the little red...

And an extra thanks for letting me borrow your tripod for a while. I'll be sure to remember to bring mine next time.

I got my spot meter in the mail Saturday afternoon, so I will be finishing off...

I would like to thank everyone who helped me get started with my camera and instant film. I managed to come home with a thoroughly decent first shot. I had a great time on Saturday and I look...

Thanks for all of the information. Now I just need to wait for everything to arrive so I can try my best to actually put it all together and see if it works.

I don't have the power supply in hand yet, but from the picture it looks like the dumb supply (on/off switch only). I'll keep my eyes open for a timer, they seem to be dirt cheap.

The local film...

Ok, I have the base and columns lined up, as well as the Dichroic II head, mixer, and power supply. I have found a 135mm lens with the 4.25" cone and the appropriate focus rail. Are there any other...

I seem to have found a Omega D Dichroic II head, mixer, and power supply that should go with the enlarger. Now I need to figure out what sort of lens I will need so I can collect the appropriate...

I have the opportunity to get the structural portion of a D4 enlarger without the head (for free). This interests me because I've noticed that there are a lot of Omega 4x5 enlargers available...

I plan to be there with my Crown Graphic. I've got my Polaroid 550 and a pack each of Fuji B&W and Color instant film to play with.

How are the Jobo 2500 series tanks or any of the other smaller looking tanks (Beseler, Paterson, etc)? They're available for quite a bit cheaper on ebay. I don't know what sort of quantity of...

On a related note, what do I need to know about the standard B&W processing chemicals? Are they safe to wash down the sink? Will they stain the sink or counter? (my sink is stainless)

I'll probably start with some sort of contact printing, even at 4x5. I tend to like 4x5 because it's still pretty easy to drag a cheap folding camera around and still get a nice big negative. :)
...

I suppose my real problem isn't the size of the apartment itself, but that the bathroom and closet are especially small (the closet is behind a sliding door in the bathroom). There is no space to...

I am fairly new to LF, but I am considering trying out some processing. I live in a fairly small apartment and have nowhere to put a real darkroom. I think I might be able to do well with a...

The nice people at Film Depot hooked me up with a Polaroid 550 for a good price, so if I can get some of the Fuji instant film this week I'll be set to start shooting this weekend. Alas, the only...

Thanks for the information. I think I'll swing down to film depot at lunch or after work to see what I can find. My film holders are pretty dusty (as is the camera, on the outside at least), so I...

I've just picked up a Crown Graphic in decent condition and I'm ready to start learning the basics of large format photography. I've dabbled a bit in 35mm and recently picked up a Nikon D5000. I'm...
