Adam is born!!!

2010-01-25T16:30:00.000-08:00

Adam is finally out!

8 lb 2 and healthy... Shay will send pictures when he can. Mom and baby are happy and healthy. It ended up being a C section, but no problems at all. Proud Daddy is smiling from ear to ear and says that he's a beautiful Mosconinio (or Mosconinho in Portuguese spelling).

Study of reclining nude (after J. Collins), graphite on paper, 8.5x11"

2010-01-13T22:01:00.001-08:00

Recently I've been getting back into drawing. I decided to challenge myself and start a series of figure studies following the French acadmie tradition and using Tony Ryder's book as a guide. This is the first small drawing coming out of this attempt.

It took about 4-5 hours of work, using the sight-size method and no mechanical tricks of any kind. I think it's an OK start. We'll see where I go from here.

Lots of fun!

Liam is not spared the heavy lifting either...

We were at Yosemite. A large snow storm was approaching and the morning mist was thick. You cold barely see the valley from the entrance of the tunnel leading to the south of the park.
The sence made me think of watercolor washes immediately, so I came back home and tried dit out...

This is my first post from this trip. There will be many more. I'm so behind. Didn't finish last years Mendocino (barely started working on those) and just touched a tiny little bit on all the good material from Yosemite and Tahoe. And these are just photos - paintings will take even longer...

HDR workflow

2009-03-04T09:06:00.000-08:00

To those of you who asked, here's some brief description of my current HDR workflow:

An often neglected topic in HDR discussion is the source image alignment problem. I like the freedom and spontaneity of working with the camera hand-held. So most of the time I don't carry around a tripod. This can make for a challenge with HDR.
Photomatix can only handle slight registration between the shots. Photoshop does better (with auto layer alignment) but still leaves a lot to be desired when there is serious registration.
What really works for me for alignment (and sometimes even for HDR and tone mapping) is PTGUI - this panoramic stitcher does a fantastic job with alignment (Windows only). And so I end up with a workflow like:

Import RAW into Lightroom (or photoshop raw)
Export the shots to 16bit TIFF images (preserve all information, and keep exposure data in EXIF)
Load them into PTGUI and align
Export the "panorama" in separate layers into new 16bit TIFF files
Load into Photomatix, generate HDR and tone map
Save processed image to a 16bit TIFF
Load into photoshop or lightroom and post-process

It takes much less time than it sounds...

Sometimes, I can get decent HDR tone mapping straight in PTGUI, and then all I need to to is export the final tone mapped image from PTGUI and then Photomatix is not needed. However, PTGUI is not nearly as flexible as Photomatix for the tone mapping step.

Also, it is possible to generate the HDR from PTGUI and then do just the tone mapping in Photomatix, but generally I got better results with Photomatix when generating the HDR in Photomatix and tone mapping in the same session. There was a mention in some article that Photomatix remembers some information that is generated during the HDR generation that it can use for better tone mapping. This info is not saved in the HDR, and that's probably why tone mapping in the same session seems to work better.

There are several good articles on HDR workflow by Uwe Steinmueller on his site, outbackphoto.

Just created this blog to see whether I can make my life easier with posting photo related issues and help to ease access to my on-line galleries.
