Cheapskate Tuesday 8: giving your photos a “painted” look without Photoshop

ab123

Here are the results of three alternative photo processing paradigms.

1: the unaltered image.

2: the same image processed with Adobe Photoshop’s “Accented Edges” filter.

3:  the original photo processed by Catherine Scott, using just her hands, some paint, and a paintbrush.

Of the two altered images, I prefer number three, because it takes the crow in a more Impressionistic direction. Catherine points out that it doesn’t use expensive software, and took less time than our so-called “1 hour” photo printing place down the street. Your results may vary.

Weekend Expedition 8: Return to Reifel!

Cannot resist these cranes! This one was calling.

Cannot resist these cranes! This one was calling.

The Weekend Expedition to Reifel Bird Sanctuary with Wild Research was a fun outing, made better by the good company and great weather. Highlights of the trip were a Great Horned Owl, Saw Whet Owl and American Bittern. Only the Bittern was a cooperative model. I tried a few low angle shots on feeding ducks, but did not have much time to work out the kinks. I think I will try to do more of this in the future, as it is an interesting and humorous perspective.

Below is a selection of the photos…Check out that lovely Bittern!

Cheapskate Tuesday 7: Cheapskate Flash Diffuser Mark II

IMG_5840

*NOTE! The instructions here are great for cutting out a pattern to fit your flash, but check out the Cheapskate Diffuser MKIII instructions for a better method of general construction

 

Adrian Thysse has just announced a macro tools workshop for you Albertans, and Alex Wild has just put up a post about diffusing an MT-24 EX, so the time is ripe for macro flash diffusion discussion. This week’s Cheapskate Tuesday is an overhaul of the Cheapskate Flash Diffuser, essentially transforming it into a small softbox. This update uses the same plastic diffuser material as well as craft “foamie” material.  A glue gun or other adhesive option is also required.

The two chief advantages to this updated device are: 1. the diffusion material stands off several more centimeters from the flash head, so the illumination of the diffuser is more even. 2. The new device is stiff and solid when mounted to your speedlight, so it won’t flop around. The disadvantages are the more complex build, larger folded size, and increased weight (48 vs. 12 g). Another disadvantage is that this is no longer universal, but must be made to fit the dimensions of a particular speedlight. Here I have illustrated a build that would work for a YongNuo 560, 565 or a Canon 580. The generalized schematics to adapt the design to any speedlight are found below. If possible, I will have some shots from the field taken with this soon.

Please follow along below for the essentials on how to construct the Cheapskate Diffuser Mark II. Just like an update to a Canon lens, this Mark II will run you three times the price. So budget around 3 dollars. Because being a PhD student wrecks my brain and hands, I had to rely on my local Master’s Student Catherine Scott to help me out with all the tough geometry, hand modelling and cutting! Pythagoras also helped immensely.

This “foamie” craft material is the basis for the modification. You will need two black sheets and two white sheets.

Using the same plastic diffusion material as in the Mk I, mark off 4 cm from each side.

For the wide sides, cut out the pictured shapes in both the white and black foamie material.

Same with the narrow sides. Make two in black and two in white.

these schematics are for designing custom diffusers for differently sized diffusion material or a different speedlight. Here is how to measure a flash head and mark off the diffuser material.

UPDATE!!!!!!!!!!!!!!!!!!!!!!!!!!

found a Camponotus alate in the hallway at school today, so I had an opportunity to test out the CFDMkII

Weekend Expedition 7: Burnaby Lake Park

IMG_5596

This male Wood Duck seemed agitated, I presume because I was between him and several females.

This week’s Weekend Expedition was a bit of a hurried affair: I wanted to get done and get on the road to return my malfunctioning Canon 60D. This camera was working Saturday night, but when I got up Sunday morning to prepare my gear discovered that my generally reliable camera body would not start. I suspected all manner of grievous harm to the motherboard, and grumpily decided that I would return it for a refund or exchange at the store where I bought it (I had bought the extended warranty).

Because such misfortune can strike at any time, I have a backup body, the Canon 450D (Rebel XSi), which I took on the trip to Burnaby Lake.
While out in the glorious sunshine, seeing the spring springing and the birds and insects becoming active, my mind was still cloudy thinking about my traitorous camera back home. Instead of fully immersing myself in the sight of testosterone-fueled combat between Canada Geese, or sunbathing fireflies, my thoughts were elsewhere, and after a couple of hours I packed up and headed home.

IMG_5643

Several Ellychnia hatchi , large, diurnal fireflies. were sunbathing on exposed bark.

IMG_5730

This Scaphinotus marginatus  (ID courtesy Todd Lawton) was a  new one for me. Generally, the most common Scaphinotus here are the larger Scaphinotus angusticollis. These odd Carabids  are specialist predators of snails, and their elongate rostrums are thought to be an adaptation for extracting them from their shells.

IMG_5577

I did not get a great shot of the behaviour, but the Canada geese are getting their spring on with some feisty combat.

When I arrived back home, I called the store asking about the procedure for returning the camera. While I was waiting on hold, I started idly wiping the battery terminals with some cloth, thinking it might just be a connection problem in the battery compartment. Sure enough, it ended up  being the case that the sole cause of the camera’s mysterious reluctance to boot was dirty contacts on the battery terminals.

Although this Weekend Expedition produced some okay shots, I find that I was dissatisfied with the day. Whereas I had planned a leisurely 4-5 hours ambling around the lake shooting birds and bugs, I ended up truncating the outing, and not really being fully present to make the most of the time I did take.

So there is a lesson in this, I think. While it is important to have a decent lenses and a working body for your expedition, it might be more important to bring a clear mind.

This Stonefly (ID anyone?) was sunbathing on a railing, and fled from my approach. After a time, it resumed sunbathing, so I could take this shot.

Even the Chrysomelids were out to soak up the rare Vancouver sunshine .

Rainforest video trapping!

Music: DJBrownBum “like a jungle”

In lieu of a more substantive post this week, I must resort to some footage of a Red Acouchi (Myoprocta exilis) coming to some Astrocaryum seeds. This I took in March of 2011 while testing out a DVR which I was going to use on the caracaras. Having this equipment on hand during the our field seasons was a cool opportunity to get some footage of interesting animals (as well as providing large portions of our data). In future posts I will put up some more of these jungle camera-trapping clips, as I think they can be fun and informative.

Cheapskate Tuesday 6: A simple flash bracket

So far on Cheapskate Tuesday I have desscribed two different ways of getting close to a subject, with macro diopters, and the use of extension tubes and cheap 50 mm lenses. I have also covered flash diffusion and radio triggers. There is one element missing for a cheapskate macro rig, and that is some kind of bracket to mount the diffused flash to the camera. This is necessary  because although it is sometime practical to hold a speedlight in one hand while shooting, it is often nice to be able to hold and fire everything with one hand free to hold back vegetation, or steady the subject.

Below is one easy option to accomplish this.
IMG_5319

On the left is a simple aluminum flash bracket (or a piece of one anyway). They can be found on ebay, if you search for “flat flash bracket”. They may run anywhere between 3 and 10 dollars. A better option would be to visit a used camera store, as they probably have oodles of these sitting in a dusty box somewhere.   The second item is an 11″ variable friction arm, also available via ebay. This device allows you to connect any two objects that both have a female 1/4″ thread. The arm allows you to flex the central joint along one axis, and a great range of movement on the ends via a ball and socket type linkage. When the main knob is tightened, the whole assembly locks rigid.  These two inexpensive items can be put together using a 1/4″ nut, some washers and a lock washer.

IMG_5308

The arm can be used to cantilever the flash (with triggers or ttl cable, and diffused!) out over or beside the subject.

IMG_5313

The flash can be oriented to either side, or the entire assembly can be rotated so the friction arm is to the left or right.

IMG_5315

The bracket can be used as a standard flash bracket as well, and can bring the flash nicely off-axis for paparazzo-style shooting with wider lenses.

See below some examples where I have used this type of bracket. I have found it is a simple, cheap and lightweight general purpose bracket for many shooting situations. .

This French Guianan toad was illuminated from above using the friction-arm mounted flash.

This setup works especially well working very close, as in this portrait of a damselfly.

This ant-mimicking spider was also amenable to use of this bracket. Because the subject is illuminated from such a close source, falloff is a problem. In an upcoming Cheapskate Tuesday, I will share how I get around this problem.

results of the Weekend Expedition to Comox

IMG_5093

As I suspected might be the case, this Weekend Expedition was more of a working holiday, as we went over to help Catherine’s parents move. The ferry rides  provided the majority of the good photo opportunities, but this is not a bad thing! A trip from the mainland to Vancouver Island provides a lot of photographic potential. Check out the results below to see what I mean.

IMG_5107

Regular ferry service between Vancouver and Vancouver Island principally services two cities: Victoria and Nanaimo (home of the Nanaimo Bar). We took the trip from Vancouver to Nanaimo, from which we got a ride  to Comox (thanks Sidnee!).

IMG_4992

The mist-enshrouded evergreen hills of BC. I used to fantasize about living here when I was a boy, imagining all the amazing animals in this relatively unspoiled province.

IMG_5004

Winter light on the seascape can do some odd things.

 

IMG_5032

One of my favorite things to do on the ferry decks is shoot gulls. It is one of the best opportunities to practice in-flight shots from all angles.

IMG_5112

On the outbound trip, there was even some blue sky. The gull looks surprised too.

IMG_5128

Saturday evening we took in some local culture. In Cumberland, there was a Taiwanese Lantern Festival.

IMG_5158

These large lanterns made for an interesting backdrop. Bounced flash off the ceiling allowed some detail to come out in Catherine and Julia.

IMG_5133

Shooting in the dark!  The ambient lighting is interesting at least.

The lantern festival culminated in a launch of aerial lanterns. I sewed up some stills into a movie to give a sense of what that looked like.

IMG_5120

This was the view on Saturday morning. On Sunday morning, the wind was raging, and dozens of eagles flew right by the window. It was too dark for photography however.

IMG_5235

The return ride was a little more choppy, but the seas are quite pretty in a grim and cold sort of way.

IMG_5261

Vancouver from the north with 18 mm (check out the boring composition…how not to use a wide lens!). This shows the full extent of downtown to UBC.

This would be the faster way to go!

Vancouver is crowded, but this looks a bit isolated even for me!
