Title says it all. My daughter is in Taos and would like to do some printing. Nothing fancy required. Do you know of possibilities?

Thank you fellow photogs.

Is there a telecentric lens available for large format? These change the rules on depth-of-field. DOF is no longer an issue, but everything is a trade. Only one magnification.

Therefore, use...

A pinhole is not a lens optically, physically, nor mathematically. A completely different beast that fools you to call it a lens.

I use Satinice; specifically the 1/8" clear type. This gives about 1/3 stop loss per layer.

The first layer is 1.5" below the LEDs, but that is for widely spaced, 1 amp LEDs. The second is...

I used one for a long time. It was fine.

My sink is that size. I built mine flat and level and adjusted with blocks under the legs. It's about 1/8" per foot and it's plenty.

With a router, cut a relief for your drain flange so it is...

4x5 Chamonix, 5x7 Deardorff, and 8x10 Deardorff. I haven't done much with any of them since the Damndemic. And the 8x10 is up for sale soon. I agree with Kirk.

There are several of these topics here already. Here's one:

I used black paper. It was a heavy stock, probably 2 point. It can be sanded or peeled thinner if needed. Or it can be stacked; glued with rubber cement, if thicker is needed. A piece of film...

The Schmidt corrector plate is an aspheric surface with a 'wave shape' cross-section. Originally used in some telescopes, it is now used for other applications. About 100 years old.

Nope.

Self portrait. Actually a 5 sec movie in mid-wave infrared (4 to 6 micron) taken with a camera I designed in 2011. So yes, it is digital and I have sinned.
...

Add a temperature column to your spreadsheet. As noted, the SW is really hot and temperatures are in the shade, of which there is none in DV.

Anything with NP after it will be busy. And...

Old steel blades from hand saws. Or, find a shop that makes springs. Cameras I've made I reused old camera springs.

1600 grit wet/dry. Any finer and it is clear.

All my Deardorffs, 3 of them, needed the ground glass repositioned. I did it by measurement, but photograph a ruler with small f/# works too.

Only saying that as one stops down, the radius of use of all the elements stops down too. At 5.6 you need the full front element. At f/22, the image is no longer in the outer fringes of the glass. ...

I use 4" gels (poly) with mine. Either handheld or in a Lee snap holder. Unless you are using f/5.6, then your image rays don't go through all the glass and your filter doesn't have to cover...

Try it. If you like soft fuzzy. These lens are probably cast, not ground, so the surface curvature could be anything.

breath still has much oxygen. We are not efficient about the conversion because CO2 is poisonous to humans. CO2 is acidifiying, but not much. Ask the coral.

Rectified AC is just higher frequency w overtones. Basically a mess unless you filter or regulate.

Buy a 120vac coil w DC contacts. A 'contacter' is such a device. Check contact currents.

Dry relay easiest. Check your ratings.

I used a PFET and an opto coupler. Tricky business.

Whatever. You want ground isolation from unit to unit.

Two days? Don't take so much gear. You'll spend your time figuring what to do, rather than doing it. Whichever camera you take, you'll have plenty to photograph.

Have fun.

The Duchess looks like a Vogue model. Was that the point? All I see is the photographer and not the person. Not to my liking.

Lots of info here and there is a link to the full blown datasheet.

With 36 LEDs on 12x12 aluminum, it is a simple 6x6...

Disclaimer: I have not made the elgatosuizo design. My comments are based on five LED sources that I've designed and used.

I'm using a 6x6 array of 1Amp LEDs made by Cree mounted on a 1/4"...

I find the flip-downs heavy too. Mostly I use different pairs of glasses for different things. All custom because my eyes are unbalanced and wonky.

Loctite 222, but nothing stronger. Loctite doesn't bind with stainless steel or anodize unless it's primed. Primer is just copper ions.

I'm sure there are other remedies without buying a...

At low angles, most surfaces reflect.

Have you tried flocked paper inside. Used in telescopes to reduce background 'stuff'.

PM sent.

Newton's Rings occur when the distance between two flat surfaces approach the wavelength of light ... and the light has some coherence. Therefore, you either need to disturb the flatness of the...

Started with trays. Then Jobo for a time. Now ABS tubes (similar to BTZS tubes).

I couldn't shuffle without problems. So when using trays, it was one at a time. That was a lot of 'dark...

I can't carry the weight that I once could.

There is an online app where you can lookup headstones. And there is a picture of each.

I purchased a 'bargain' 35mm camera from KEH. Only thing 'wrong' was someone had removed the camera's name from the top plate. Somehow, carefully, removed the camera name, etc. silk screen. Other...
