A Diffusely Lit Chicken Adobo

One of our quick set-and-forget meals is chicken adobo, via slow cooker.  Especially fast this time considering we threw together the onions, ginger, soy sauce, and rice vinegar along with frozen chicken thighs into the slow cooker set to HI for 5 hours, while finishing lunch.

Chicken Adobo...from the slow cooker

In terms of recipe, there’s not much to write about since it mostly follows this recipe with the exception of using Tamari sauce instead of traditional soy sauce.  I’m not going to attempt to claim any authenticity on how this dish is made, but it makes for a mean stew over rice.

Rolling your eyes away from the wish-you-could-taste it bowl towards the spoon gives away me using a new photography toy for this shot.

Our dining table which doubles as the default naturally-lit food photo staging platform is positioned in front of a large sliding glass door.  I had wanted to help reduce some shadows within the bowl as well as softening the light source, when I remembered I had obtained but not-yet-used a combo light diffuser/reflector kit.

Diffuser disc with reversible disc sleeve for solid white, gold, silver, or black.

Comparing my kit to the Neewer 43-inch / 110cm 5-in-1 Collapsible Multi-Disc Light Reflector[*] leads me to believe this kit is manufactured and labeled for various retailers under different names.

With the camera on a tripod set to self-timer, I composed the shot while holding the diffuser disc (without the reflective sleeve) to cover the bowl + place setting.  The immediate effect was the shadow on the inside-right of the bowl was much attenuated, and the softened lighting made the chicken thigh stand out more.

I look forward to making more use of the diffuser disc and the included sleeve (silver, white, gold reflective colors, and black absorbent color).


The Neewer 43-inch / 110cm 5-in-1 Collapsible Multi-Disc Light Reflector[*] looks to be identical to my combo diffuser/reflector kit.  My bag says “raya” on it, and going to the listed “rayalighting.com” redirects to a corporate holding site which only references the raya brand as “coming soon”, which supports my white-label theory.

I originally obtained my kit a few months ago from another specialty retail shop using some bonus store credit.  The Neewer branded kit comes in about $2 less than what I would have paid for mine.

For $17.50 at time of writing, it seems to be a low-risk purchase for something that could be very useful to have on hand, and to get into lighting techniques whether you’re shooting with a cell phone, point-and-shoot, SLR, medium format…etc.  The diffuser disc definitely softens light, and the reflectors can light up faces outdoors.

Why a Polarizing filter should be in your go bag.

In making the last featured meal, I had taken a shot of our rice cooker, positioned to the side of our sink which is in front of a window.

No polarizer used on Left. Polarizer on Right

No polarizing filter used on Left. Polarizing filter used on Right

Immediately notice that between the two samples, the photo taken with a polarizing filter has much reduced reflections and glare from the rice cooker’s glass lid and from our granite counter-top.  Color saturation is also increased on the right photo.

Polarizing filters earn their keep in a camera bag, for indoor and outdoor shots.

For almost as long as I’ve owned the workhorse lens (which was also my first owned lens), I’ve had a Hoya 58mm circular polarizing filter as a ride-along.

hoyaCIRPLI obtained the polarizing filter above in 2006 from a local mom-and-pop photography shop which, like a lot of other brick-and-mortar retail camera shops, are no longer.  Based on what I paid for it (~$50, incl. shop markup and the have-it-now premium), I think the closest equivalent make today is the Hoya alpha Circular Polarizer Filter[*] available in various filter ring sizes.

If  you’re interested in a brief science of how polarizing filters work, find this wiki.  Basically, light that is reflected from non-metallic surfaces (e.g. glass, water) becomes polarized, and the polarized filter rotated to only pass light perpendicular to the reflected light will absorb much of the reflected light.

In practice, a polarizing filter has its greatest effect when used to take a picture 90° from the sun.  (around noon or early afternoon, depending on geographical location).

From our back yard, here’s a sample of outdoor photos taken without using a polarizing filter, polarizing filter attached rotated at minimum effect, and then at maximum effect:

No Polarizing Filter

No Polarizing Filter

Polarizing filter at minimum

Polarizing filter at minimum

Polarizing Filter at maximum effect

Polarizing Filter at maximum effect

 

 

 

 

 

 

In the samples above, just adding the polarizing filter at minimum effect increased contrast and saturation of the concrete fence and fruit trees.  Rotating the filter’s front element to maximum effect makes a bluer sky.

While we were at a park recently, I was able to capture these differences between min and max polarizing effect:

Polarizing Filter at maximum effect

Polarizing Filter at maximum effect

Polarizing Filter at minimum effect

Polarizing Filter at minimum effect

The park shots were taken later in an afternoon day than from the noon-ish shots of our back yard.  Here, the polarizing filter at maximum really changed the skyline, and significantly lightened up the mountains and grassy terrain.  The baseball fences stand out more in the max polarized shot.

Since a polarizing filter drops down the amount of light passing through, you’ll want to watch your shutter/aperture values from going beyond where you want them.  Increase your ISO 1-2 steps if you want to keep similar shutter/aperture as without a polarizing filter.

When properly used, a polarizing filter can get you some really awesome photos out of the camera with effects that can’t really be simulated in software post-process.


The Hoya alpha Circular Polarizer Filters[*] are available for what appears to be a comprehensive range of common lens filter diameters.  To find out which filter size you need for your lens, you can look up the filter diameter specification for your lens.  This may be found in the product documentation, or often its labeled on the lens itself:

lensThreadingSizeLook for a millimeter (mm) label that’s prefixed with a slashed-zero (∅).  In the example above: ∅58mm.

If there’s multiple lenses which you’d like use a polarizing filter on, and the lenses have close but different filter diameters, one option is to buy 1 large filter and a set of step-up/down rings (e.g. Fotodiox 7 Step Up Ring Filter Adapter Set, Anodized Aluminum, 49-52mm, 52-55mm, 55-58mm, 58-62mm, 62-67mm, 67-72mm, 72-77mm[*]).

If your current camera of choice is a kind that uses a fixed lens and/or just doesn’t have a native filter thread, see if your camera model has a filter attachment accessory available.  Or, use a little finessing:

Dinner’s ready…we’re having sushi!

Sushi has been a household favorite.   Being the frugal family we reserved the restaurant sushi for special occasions and went with store bought for the occasional easy meal.  However, our fondness of sushi has grown much more since we started rolling our own about a year ago.

Homemade Sushi

Homemade Sushi

Making the California Rolls at home mean sushi without having to run out to the grocery or warehouse store and eating your fill without breaking the bank.

Fortunately, keeping a stock of ingredients and utensils is rather minimal:

IMG_4908e

What we use to make California Rolls

You’ll want to cook the rice at least far enough ahead of time to allow it to cool to at least “slightly warm”.  Meanwhile, bring 1 cup of the rice vinegar with 1/2 cup of white sugar to a simmer in a small pot until you can stir in the sugar.  Migrate the rice into a non-metallic bowl, pour in the sugared vinegar and mix together.

IMG_4919 IMG_4920

To prep the filling, chop the imitation crab meat (thaw first if frozen) into a container, season with salt, pepper, and other optional seasonings to taste.  Integrate mayo into mix to desired consistency.

IMG_4925e IMG_4929e  

Slice your avocado.  I’d recommend cutting avocados as you need them.

IMG_4934e

Now that we finished Mise en place, its time to get rolling.  Set up your workbench conveniently, wrap the sushi mat with plastic wrap, and lay a sheet of nori on the covered mat.

IMG_4935c

Making sushi is one of those things that as much as you can read and watch how-to videos, the best way is to try and learn tips and techniques that work for you.  So the following is what I’ve learned to do.  Follow or modify as fit.

With the rice paddle, lay some rice on the nori.

IMG_4940

To help with spreading the rice across the nori, dip the paddle in water and using the back side gently apply pressure to spread the rice.  Holding onto corner of uncovered nori helps with sliding around.  Work to cover the nori with a thin surface of rice while leaving about 1/2 inch from the top.

IMG_4941 IMG_4942

Place avocado slices to cover a row about in the middle of the rice section.  Top with a layer of the meat filling

IMG_4944 IMG_4946

To roll: pick up the mat at the bottom (edge closest to you) to fold the nori+rice over the avocado+filling.  Tuck back any excess bamboo mat that would otherwise start rolling into the sushi.

IMG_4948 IMG_4949

Pick up the mat at the top (edge initially farthest from you) such that the rice layer meets up with the sushi filling.

IMG_4951

To complete the nori overlap, continue rolling the top of the rice+nori while unrolling the bottom part of the sushi mat.

IMG_4953 IMG_4954

With the sushi rolled onto itself, wrap the top edge of the bamboo mat along the sushi and overlap it with the bottom edge of the bamboo mat.

IMG_4955

Pick up the bamboo-mat wrapped roll and give it a gentle-to-moderate squeeze evenly along the roll.  Unwrap bamboo to reveal finished sushi roll.

IMG_4956Remove roll from mat.  Using a wet knife, slice the roll.

IMG_4958

Serve with dipping condiments.  Soy sauce is a good choice.Coconut Secret Organic Raw Coconut Aminos Soy-Free Seasoning Sauce[*]
is an alternative if wheat and soy is a concern.

IMG_4971

Kanpai!!!!


The ONE ORGANIC Sushi Nori[*] is the strongly recommended item to get, if only for the value.  It’s been a hair under $12 for 50 sheets ever since we found out about it, and I *just* now noticed they’re offering a 100 sheet pack (2x 50 sheets package) for slightly less unit price.  There’s only been a few local grocery stores around us that even stock full-sheet nori, and at about $5 for 10 sheets, don’t come near as low-cost as the ONE ORGANIC.

IMG_4914cre IMG_4917cs

We’ve been fortunate to have discovered the Hampton Creek, Just Mayo, Original, Gluten Free, Soy Free, Egg Free[*] since egg allergy has surfaced in our home. We’ve been able to locally source this mayo at a better price than on Amazon, even though store inventory has occasionally been spotty. (yes we hold on to extras in our pantry).

The Coconut Secret Organic Raw Coconut Aminos Soy-Free Seasoning Sauce[*] has been a good soy sauce dipping sub-in for those in our home with wheat and soy allergy/sensitivity.  Pricing here is fairly in-line with available local vendors.

I’d suggest picking up the Botan Musenmai Calrose Rice from a brick-and-mortar store, unless you’re not within practical access to a shop that stocks it, or you already use Amazon Prime Pantry.

Basic operating principles of cameras

A brief hand hand-sketched overview on how cameras work:

From outside the camera to inside, how a photo is captured.

From outside the camera to inside, how a photo is captured.

This post is my attempt to explain how the most fundamental parts play together inside a lens/camera and how they contribute to the resultant photo.  Certainly use this as a starting point to go out and research using more comprehensive sources.

In the example below of taking a photo of a flower, the light travel through a lens, an aperture and a shutter to get to an imaging medium.

  1. Lens: the optical component that gets the subject (e.g. the flower) in focus to the camera.  Uhm..there’s a lot of physics involved in explaining how lens works but for now we’ll use that to get going.  Lens are described in “focal length”.  Practically, the focal length is proportional to the angle of view.
    1. a shorter focal length (such as 20mm, or “wide angle” lens) gives a wide view to enable you to capture more within shot.  Think landscapes, or taking pictures of people where you can’t back up far away.  Sample: Canon EF 20mm f/2.8
    2. a longer focal length (“Telephoto Lens”) gives you a narrow view, to zoom in objects far away to fill in the frame.   An extreme far reaching sample:
      Canon EF 800mm f/5.6L IS USM Super Telephoto Lens
  2. Aperture: The diaphragm (or iris) that widens or narrows to control how much light passes through to reach the imaging medium.  Aperture is denoted in “F-numbers” (f/N, where N is the f-number).  An f-number is basically a ratio of the lens’ focal length to the diameter of the aperture.  While I’ve drawn the aperture above as a set of mechanical closing blades/leaves, there are various designs of apertures.
    1. A wider aperture (lower f-number, such as f/2.0) allows for more light to pass though over a given time, while giving you a shallow depth-of-field.
    2. A narrow aperture (higher f-number, such as f/16), allows less light to pass through over a given time, while providing a deeper depth-of-field.
  3. Shutter: the plane that opens, and then immediately closes to allow light to pass through to expose the imaging medium.  Typically this is accomplished with a first
    “curtain”opening the frame, while second “curtain” chases the first “curtain” to evenly expose the imaging medium via a sliding window.  While I’ve drawn a shutter above to represent a vertical-travel focal plane shutter, there are various designs of shutters.  In operation, a camera shutter is parametrized as time in seconds, or fractions of seconds. (e.g. 2 seconds, 1/4th second, 1/60th second)

    1. A slower shutter speed exposes the imaging medium over a longer time.
    2. A faster shutter speed exposes the imaging medium over less time.
  4. Imaging Medium: this is the component onto which the light from outside the lens and passes through the internal lens/camera components is exposed.  Back in my day, this was film that we loaded in the back of a camera.  Nowadays it typically refers to an image sensor.  The imaging medium is characterized/set by its sensitivity, referred to as ISO.
    1. A less sensitive sensor setting (e.g. ISO 100) needs more time to absorb light, but tends to less noisy (digital) or grainy (film).
    2. A more sensitive sensor setting (e.g. ISO 6400) needs less time to absorb light, but tends to be more noisy (digital) or grainy (film).

Hopefully this provides a better understanding of that’s going on when you operate a camera.  Look for future posts to build upon this article.


Its honestly silly to actually promote products on a “primer” page, so the external product links are really more for showing examples.  I wouldn’t expect anyone to immediately rush out and get a wide angle lens, and especially not a monster $13k+ telephoto lens.

I definitely DO NOT OWN a 800mm telephoto lens at time of this writing, and therefore express no opinion of it.  However, I do own and heavily use a Canon EF 20mm f/2.8

My arts skills (or lack there of)

My son wanted to draw together before bed this evening. I had already pondered on this revelation of my arts skills recently, but this captures it best:

My son started off with his blue train, but then wanted to draw a house like Dad's.

Our son is of preschool age, and has a good grasp of shapes and basic drawing abilities.  Which is not very far from where I left off, apparently from kindergarten arts class.

If there’s one life worthy tip to get from this blog it is this: cherish every moment you can while you can.  (and take as many photos/videos along the way).  Tomorrow, that shadow on the left won’t be the same.

Ladybug in the weeds

Its spring time and the weeds are aggressively sprouting up.  Working through weeding this morning, I came across this little bug:

Honey Tamari Chicken …and Welcome!

Let’s cut right into the cold open: Dinner from last night.  New recipe tested and approved for future meals!

Oven baked Honey Tamari and Wine marinated chicken wings.  Served with brown rice and grilled vegetables.

Oven baked Honey Tamari and Wine marinated chicken wings. Served with brown rice and grilled vegetables.

Discounting the time to thaw/marinate the chicken itself, cook time was about 30 minutes.  So with a little advance prep, this qualifies for weeknight rotation.
I mostly followed this recipe for Honey Soy Sauce Chicken but with 2 modifications:

  1. Used Tamari Sauce instead of regular soy sauce.  While I like my standby Kikkoman, our household manages wheat allergies.  Traditional soy sauce blends are a mix of soy and wheat.  Tamari sauce is made with little or no-wheat, depending on make, and has a darker appearance and richer flavor than traditional all-purpose soy sauces.
  2. Used unfinished Trader Joe’s/Charles Shaw Pinot Grigio since I didn’t have saki or dry sherry at hand.

..and if you got this far, Welcome to PTvAvM.com, yet another blog in the internets, or as I’m claiming: “a photo blog and a blog about photography”.  Today, this post hits the first half of the tagline, where a photo is shared and some context is discussed.  I intend to publish more photos of varying subjects (not all #foodporn, I promise..but we do eat a lot), as well as more in-depth articles on photography knowledge, tools, and tips & tricks I’d like to share from my photography hobby.
