Quit Using Auto White Balance

White Balance Fixed 50mm, f/1.4, 1/160s

Ever since taking Raul Touzon’s workshop I almost never shoot using auto white balance (AWB).  The camera rarely gets the white balance correct when it guesses, and the photos from a single shoot are often inconsistent in color when they are shot with AWB.  If they are going to be “wrong” when AWB is used, you might as well guess wrong yourself by choosing one of the manual white balance modes — at least the images will be consistent with each other.

Ideally one would shoot an image of a gray card (or a similar type of product) which has a known color and use it either to set a custom white balance in the camera or to sample it in software to do an automatic adjustment.  If I don’t use a gray card, I pick a WB mode (my default is “daylight”) and shoot everything with that.  In Lightroom I either sample a white point to fix up the WB or I adjust it to taste (I might even want to make it wacky here and there).

The shot above was snapped in the kitchen while I was testing my newly-repaired camper.  Canon had changed all my default settings of course and I don’t even remember what WB was set in the camera.  No matter, I simply used the WB eye dropper to sample one of the white polka dots on my daughter’s dress.  The image above is the result — straight out of the camera except for the white balance.

Chair Abstract

Chair Abstract 50mm, f/1.4, 1/50s, ISO 200

Just like the kite photo I recently posted, this image is out of the ordinary for me — I don’t shoot many abstract or fine art types of photos.  During the week I picked up my Canon 5D mkii from being repaired [related sad story below] and yesterday got a chance to fully check it out.  I popped my 50mm f/1.4 lens on the body and started plinking.  As I sat at our little breakfast table I opened the lens up completely and started shooting through the rails of one of the chair backs.  There were a lot of colorful things in the background which were nicely blurred by the wide aperture and close focus distance.  I then started shooting while moving the camera up and down, resulting in the image above.  I rather like it.  The image is straight out of the camera except for cropping.

So the sad story is this:  This year I decided to try shooting some pictures at a fireworks show.  I’d never done it — I’d rather concentrate on *watching* the fireworks and it just seemed like a headache overall.  Before the fireworks we attended a BBQ dinner catered by the Salt Lick and as dusk fell I hauled out the camera and tripod and began getting set up.  I put my wireless remote into the cameras hot shoe, put the camera on the tripod, then proceeded to adjust the length of the tripod legs.  I heard a loud crash — my 5D mkii hitting the pavement from a height of about 5 feet.  Looking on the bright side, the camera had turned over on the way down and landed flat on the wireless remote which was in many pieces all around us.  That definitely spared me from the damage I could have had.  The camera “worked” here and there but mostly gave an error.  It would even randomly try to focus the lens — when the power switch was off!  Anyway…a couple hundred dollars later I have my camera back refurbished and sporting a new shutter box and mirror assembly.  I managed to put all the remote pieces together but it was dead as a doornail.


The Lone Kite

Lone Kite

I’m not much for the minimalist thing in general but I’ve always liked this picture.  It was taken from the beach — looking inland over the dunes — in Port Aransas, TX.  While swimming and fishing with the kids one evening I happened to look back and see this kite all by itself in the sky.  I’m not sure what else to say other than “I though it was kind of cool”.  Adding to the cool factor IMO was the clear sky.  Normally we photographers like dramatic skies but that would take away from this scene in my estimation.


Storm Panorama

Storm Panorama 70mm, f/5.6, 1/180s, ISO 200, 10 frames

It’s pouring rain again tonight.  Lots of lightning and thunder too…awesome.  Last night after the rain I noticed some clouds to the east so I shot about 20 handheld frames along the horizon.  The above image was cropped from the resulting stitched panorama (probably about 10 frames worth).  I did some basic contrast adjustments in Photoshop after the stitch then went back into Lightroom.  I’d recently seen a very cool cloud/lightning image done in black and white and decided to go that route with this one.  I used the channel mixer in Lightroom to adjust the image to taste.  In very rough terms that meant darkening the blues and brightening the reds.


Working (Young) Men

I Think I Need A New Hat…

IMO an important part of growing up is learning how to work.  I’ll say the caveats up front: We’re not slave drivers, we have a lot of fun too, blah, blah, blah.  We’ve finally had our burn ban lifted since we’ve been receiving some rain lately.  Our burn pile has been growing, and growing, and growing — especially since it includes an old carpenter ant tunneled playscape.  The boys have been anxious to get the fire going (all boys are pyros, no?) so I put off the rest of my to-do list and spent the afternoon burning.  Once it was stoked we really couldn’t add wood very fast (at least not if we wanted to keep it under control) so the boys played in the wood pile and one even built a mini fort inside the pile.  I reminded him to watch for snakes and he just said, “All I see is sticks”.  After a long pause I heard him mutter, “But I guess the snakes match the sticks…”.

I had my daughter bring out my Canon 50D so I could grab some pics.  I had only snapped a couple and it started to rain so that camera got put away.  I would have liked to switch lenses as the telephoto lens compressed the scene a bit much for my liking, but the weather didn’t cooperate.  [It was a typically unpredictable Texas weather day: hot and sunny in the morning, thunderstorms whipped up and it poured, went back to bright and sunny (and humid), and as I write I hear thunder again]  I did get out my Canon S90 later and got a couple more pictures.  The top photo was the 50D, bottom was the S90.


Under The (Harbor) Bridge

Harbor Bridge flies high over the Corpus Christi Ship Channel and whenever I’m in this parking lot (Texas State Aquarium) I find this vantage  – and vanishing — point rather interesting.  I finally snagged a picture of it on our last trip.  It wasn’t prime time for photography but the cloud cover helped.  There are probably many interesting views and compositions to be had here.  The title comes from the Red Hot Chili Peppers song…I always think of it when I’m here.

The image is an HDR made from 3 frames.  Using HDR helped keep the sky in check somewhat and bring a *little* out of the shadows.  I always try to keep plenty of “dark” (i.e. shadows) in my HDRs.


Armadillos Again

My son spotted these little nine-banded armadillos in our back yard last night so we walked out and took some pictures.  Armadillos don’t spook all that easily — maybe because they have their face buried in the dirt half the time (notice the dirty snout) — so we walked up pretty close and they worked their way toward us.  I squatted down to take pictures and after a few seconds one of them stopped rooting in the dirt and walked right over to me like a dog who wanted to be scratched — stopped about a foot and a half from me.  I had a “hey this is cool” thought but immediately switched to “I don’t want some wild animal messing with my kids”.  I decided to pick it up by the shell like my older son used to do but as soon as I moved he bounded off (Armadillos do a kind of bounding hop when they want to move fast).

On our land there’s plenty of wild landscape for armadillos to root around in but many people find these to be quite a nuisance.  They’re not quite as destructive as a wild hog but armadillos can destroy landscape beds in a hurry.  Sometimes an armadillo takes a liking to particular flower beds and revisits them night after night until the homeowner has had enough and…well, never mind :-)


Winter Dresses…In July

Winter Dresses 90mm, f/2.8, 1/250s, ISO 200

I’ve been very delinquent in taking the picture above — my youngest girls in their matching winter dresses.  Between the baby’s sleeping schedule, weather, and that general “don’t feel like doing it now” feeling that we all get (wasn’t just me) we haven’t gotten these done.  I took the day off today and I made it a definite to-do item for this morning when our infant (“Dolly” as we often call her) is usually happiest.  We ended up pushing it a little — Dolly was ready for bed by the time we were done.

The usual caveats apply: I don’t like this or that, I’m not happy with the light (we waited too late in the morning), I don’t like the setting/background, and I’d change/fix/tweak many things.  There wasn’t so much posing as there was “Hold her and look at the camera quick before she gets fussy”.  However, my wife says: “I don’t care about the professional photo — I just want a picture of them together with their dresses so get it done”.  It’s hard for me not to try to make everything as professional looking as I can, however meager my attempts may be.

Exposure was a bit tricky.  The dark skin, light skin combination was challenging to balance (always takes some effort in our family pictures since we have four races and a wide range of skin tones).  I chose to use no additional lighting — we just wanted to get this done and not fiddle with triggers, umbrella, and adjusting flash power.  The sun was in and out of the clouds which affected the exposure dramatically.  Ultimately I determined my exposure by metering Dolly’s light skin to avoid blowing it out (I shot in manual mode).  For my taste we couldn’t go any brighter than you see above and we got sufficient exposure in the dark skin so we could make do.  There were of course the usual difficulties in getting two children to look good at the same time.  The littlest didn’t cooperate very well — she wasn’t a complete crank but wasn’t her usually smily self.  In the end I ended up swapping a head to get them both looking good.  I lightened the dark skin a bit more and tweaked the image with several curves, exposure, and saturation adjustment layers.


Happy Independence Day!

Love 24mm, f/13, 20s

I wish I had a photograph with some deep meaning behind it (maybe I’ll come up with one tomorrow), but all I have is this shot taken two years ago.  My wife was out of town over the July 4th holiday so I sent this to her.  This was my 2nd or 3rd try — kind of challenging to write backwards neatly in the air.

Hope all my U.S. friends have a great holiday!


Jesus Loves The Little Children

The Line 70mm, f/6.3, 1/200s, ISO 200, flash

I’m sticking with the pool theme for this post.  We recently were invited to swim at a friend’s pool (cheers all around from the kids) and I decided to lug the camera along to get some pictures.  It was 5pm and the sun was high in the sky.  Fortunately when the kids were on the diving board the sun was slightly behind — meaning that if I could manage to get *enough* light reflected off the kids’ faces it would at least be *even-ish* light.  Coming up with that light — while saving the background somewhat — was the first challenge then.

Belly Flop!!! 70mm, f/6.3, 1/500s, ISO 200, flash (high speed sync)

The next challenge was the huge dynamic range in the skin tones.  In the song “Jesus Loves The Little Children” the line goes “Red and yellow, black and white, they are precious in His sight”.  We didn’t have “yellow” but we had red, black, and white figuratively speaking.  If you light for the lightest skin the darkest skin might be way too underexposed.  Expose for the darkest skin and the lightest gets completely blown out in the bright sunlight.  The challenge was to maintain the best balance in the situation — via my camera and flash settings.

(Most of) the Gang 70mm, f/4.5, 1/200s, ISO 200, flash

My gear: Canon 5D mkii, Canon 70-200mm f/2.8 L, and Canon 580exii flash gel’ed with a 1/4 CTO.  I started out using shutter speeds of 1/200 to 1/250s to stay within the sync speed of the flash.  This was reasonable for much of the action and gave me quite a bit of flash power, which I needed when shooting from these distances (50′+).  Remember that the light follows the inverse square law — double the distance and you are only left with 1/4 the light.  Later I switched to using high-speed sync which allowed shutter speeds up to 1/500s to freeze the action but reduces the power that the flash can put out.  Both methods were effective in their own way.  With the 5D mkii I also had ISO as a lever.  I didn’t want to go too high with it (but I did use up to 3200 some of the time).  A higher ISO also reduces the need for so much flash power but you pay in noise.  Note that sometimes when using flash in bright light you *can’t* go very high with the ISO because the flash sync speed is a “long” shutter speed (relative to the overall brightness in the scene) and is allowing a lot of light to hit the sensor. In summary, I can’t tell you what the “best” settings are for a situation you might be shooting, but hopefully I’ve given you enough info to jump start your thoughts and get you experimenting with it.  Keep in mind that in the evening the light changes rapidly so you’ll have to adjust for that as well.

Jump! 70mm, f/6.3, 1/320s, ISO 200, flash (high speed sync)

In Lightroom I still had to use an adjustment brush to even out the exposure of the faces a bit (in most pictures).  All in all, I was very happy with the way they turned out.  The important parts of the backgrounds were preserved and the kids are exposed well enough.  There’s always plenty of room for improvement though.


Pool Monster

Pool Monster 70mm, f/13, 1/125s, fill flash

My son leaping out of the water pretending to be a monster.  I love how the motion makes his hands look like claws.  And the mask?  Well, nothing needs to be said.

It was in the middle of a bright sunny afternoon — terrible time for photographs.  I used a flash so that I could dial down the ambient a bit.  We took several shots like this, using a fast-ish shutter speed but not so fast that it froze all motion.  In post I processed things pretty heavily in Lightroom — lots of contrast and clarity.
