#66897 How Do You Take Photographs And Keep Them Consistent?

Posted by JBaymore on 29 September 2014 - 10:51 PM

Try to find a course on digital imaging. You'll learn amazing things. Like how certain file types deteriorate every time you open them.

 

If you camera supports RAW files...... use them not jpgs and the like.

 

Learn to use Photoshop.

 

Remember to white balance the camera before each shooting session.

 

Let your lights "warm up" before shootiong.... the color temperature changes a bit. Let em' stabilize.

 

Learn to use the in-camera metering system...... average weighting versus spot and so on.

 

Learn to use reflector sheets to fix lighting.... (can be a simple as a sheet of white paper).

 

As Mea said... bracket exposures like you used to do for that strange stuff........ film. ;)

 

Use difusers on all light sources. Bounce the light when possible.

 

Standardize your backdrop material.

#66772 Cataloguing Glazes

That is what computers do very well.

 

Skip paper... go digital.

Digitalfire Insight glaze software.

 

It allows all sort of sorting codes, including any custom ones you want to make up, and also attaching image files to recipes and such. 

 

Just remember to BACK UP anythibng on a computer!

 

(And also BACK UP those paper books or card files.  Many a potter has lost valuable info when thoise books get destroyed by flood or fire or simple mislaid.)

#66406 How Many "hand Builders" Here?

Posted by JBaymore on 20 September 2014 - 07:49 AM

My work is about 50% - 50%. Or maybe at most 60% wheel / 40% handbuilt.

 

Slab, coil, pinch, total subtractive (carving),press mold all get used.

 

BTW....... start thinking of the wheel as a just way to potentially handbuild. A wheel is just a way to make some forms with clay that have certain characteristics. You can then cut, stack, dis-assemble, re-assemble, re-orient those pieces into new objects at will. (On of our courses we teach at the college is "Sculpture on the Wheel".)

#66312 Soda Ash Wash And Electric Firing

Posted by JBaymore on 18 September 2014 - 08:11 AM

If you start doing whole loads of this on the pieces... expect decreased element life.  But that is the "cost of doing business" to get the effect if you like it.  Will the result let you charge a bunch more for your work?  If so... just do it and replace elements more often.

 

A single piece here and there ... if kept from being right up against the area of the element... is not going to be detrimental.

 

Any soda bearing glazes that tyou are firing in the kiln are already outgassing soda into the atmosphere.  SO a whole load of soad feldspar glazed wares is doing as much as a single piece or two with this treatment.

Toshio Ohi San of Japan measured one of my mizusashi opening with his fist.

I love how folks like that tend to 'cut to the chase' in such simple ways. ;)

#65372 Wood Fired Kilns

Posted by JBaymore on 30 August 2014 - 09:34 AM

Babs,

 

Wood type can change when firing... but does not always HAVE to. 

 

Sometimes the change is due to limitations in the kiln's design (usually air handling capacity......but sometimes total refractory insulation value).  Soft woods like pine, hemlock, fir and such release their heat very rapidly when compared to hard woods like oak and maple.   So if a specific kiln has trouble getting to temperature at the end of the firing cycle when heat losses are starting to become really significant.... some folks switch to soft wood to do that last litle "push".

 

On a kiln that is being fired for natural ash deposit glazing (shizenyu in Japanese), the chemistry of the different ash from different species cause different effects. So when you switch woods, you get a bit of a "layering" effect on the surfaces developed like layering different glazes.  More subtle... but there.

 

Some folks are lucky enough to be able to fire with a particular wood species for the entire firing.  Just like in ash glazes, the different ash produces different effects.

 

One of my friends in Japan once tried that with a wood known as hiba, a type of cedar.  He had never used that alone before.  It turned out that for a given volume of cords of wood burnt in a firing of the anagama..... that species did not produce all that much ash!  Less than with the other woods he typically fired with (mainly Japanese red pine).  BUT......... the ash that it did produce produced a beautiful yellow shizenyu on the dark reddish clay body (think BIzen-yaki).  Beautiful stuff. 

 

I typically fire my noborigama now with mixed hardwoods.  Oak and maple mainly, with a little birch.  I used to fire it with all scrap sawmill pine and hemlock......... but all of the sawmills in the local area have closed due to the disapearance of  the lumber industry in these parts.  Hard to find that kind of scrap wood around here anymore.  It ticks me off.  I started out usingt wood from a mill about 1 1/2 miles from my kiln.  That scrap wood source radius slowly speread out to about 30 miles over the years.  Now...... I'd have to go very far afield to get that kind of scrap wood anymore.

 

The VERY few mills that still exist around here at all are now set up to instantly chip all the slab and edgings (using fuel) and blow that stuff into a tractor trailer bin... so that it can be sent by a big truck (consuming more fuel) to a central company's location (often a lot of miles away), then use yet more fuel energy to process it into nice consumer-friendly wood pellets, so that it can then be shipped by truck (more fuel energy applied) back to a retail store somewhere, so that it can then be bought by consumers and taken home (more fuel used by the car) and burned in a home pellet stove (that uses electricity to power the auger that feeds the stuff into the stove....more energy applied).  Yeah.... totally absurd.  Just burn the darn wood as wood as close to the original source as possibe!!!!!!.  But they won;t save the stuff for me...... even if I offer to pay an equal price for it to what they get for the ships or even a bit more.  Too much trouble for them.

#65135 How Would You Describe Your Current Studio Location. Suburban Garage, Urban B...

Posted by JBaymore on 26 August 2014 - 02:51 PM

Converted 200 +/- year old barn attached to a center chimney colonial in a formerly rural... now less rural....... section of southern NH. 1000 sq. ft main studio, 1000 sq. ft. materials storage, and 1000 sq. ft. not used yet. Two shed-roofed outbuildings that house kilns. One gas kiln in one, and one noborigama in the other. One small electric kiln, one propane gas kiln, one wood kiln.

 

All sit along the banks of a set of rapids on the Souhegan River. Great sounds and views.

#65115 Irregular Bowls

Posted by JBaymore on 26 August 2014 - 12:21 PM

This will seem contradictory..........

 

First learn to throw incredibly "tight".  Totally and compulsively symmetrical. Like a machine.

 

It will take a long while.

 

Then the loosness you seek is possible.

#64874 New Hampshire Institute Of Art Anagama Build - Images

Posted by JBaymore on 21 August 2014 - 09:44 PM

Day 12 of the NHIA anagama construction with my kiln class came and went today....... with most of us working from 9 AM until about 8:30 PM (along with torrential rain for cleaning up at the end of the day). Today was the "magic moment" wh...en the three sections of main arch forms came out and we officially had an "inside". Front firebox step arches started, more steelwork done, smoke chamber interior wall started, rear wall started, a bit more chimney added above the roof line before the rain, and horizontal flue connection to chimney worked on. Busy and LONG day.

Yesterday was Day 8 of the NHIA anagama construction with my kiln class. A slow detail oriented day as we got ready to start on the arch. Test fitting of bricks, leveling the skews with castable, checking positions of features like steelwork, and then starting to lay arch bricks. The chimney also rises.

And Day 5 is now complete. BEAUTIFUL fall-like weather today.  We did some indoor technical "chalk talk" stuff indoors for the morning, and then resumed hands-on construction in the afternoon.
