Just under three months ago I started entering FIAP salons. These salons are basically photo competitions in which a certain percentage of the entered images are ‘accepted’, and a smaller percentage again are awarded medals. So it’s an very satisfying to have an image accepted.
- From Wikipedia: FIAP is the Fédération Internationale de l’Art Photographique, (Eng. The International Federation of Photographic Art), and is an international organization of national associations of photography. More than 85 national associations are members, comprising nearly one million individual photographers.
I recently did a shoot where I was shooting macro shots of precious gems. Each shot needed to be reviewed for focus, clarity, dust spots, etc before moving on to the next gem. The preview screen at the back of my Canon EOS 5D Mark II is normally a great screen, but just didnt cut it in this situation, when more than one person needs to look at an image to approve it or bin it. I needed to be able to get the images onto a full screen device quickly for preview. So, I looked into various forms of previewing images on a full screen device (PC, laptop) as they are being taken, from card swapping to usb tethering, to wireless tethering. Here’s the list, followed by a description of each method with the pros and cons of each.
- Card Swapping – The manual method of taking the card out of the camera, etc.
- USB (as external drive) – plugging in a usb cable to download images
- USB (using EOS Utility) – Automatic download and preview of images as they are taken
- Eye-Fi – (Not currently supported for Compact Flash based cameras, but worth mentioning)
- Canon WFT-E4 Wireless Grip – Full wireless tethering with WiFi
1. Card Swapping This option is not really tethering at all, and simply involves taking the Compact Flash card out of the camera, inserting it into a Card reader on the PC, uploading the images, and reviewing them that way. Pros: No cost. (apart from when you wear out your CF slot in your camera) Cons: Slow and work intensive. Lots of interruptions to workflow.
2. USB (as external drive). This option is not much better than option 1. It involves plugging a usb cable into the camera, and downloading the images onto a PC, where they can then be previewed. Also not a good option when you consider option 3 is enabled by installing some free software that comes with the camera.
Pros: Cheap, only USB cable needed. Only camera drivers needed on the PC
Cons: Repeated insertions of the usb cable into the camera. Camera cannot be used while it’s mounted as an external drive on the PC.
3. USB (using EOS Utility)
Now we’re getting into the useful area of genuine tethering. This method uses the EOS Utility that comes with the camera, and allows the camera to be used while taking images, and each image is sent to the PC as it is taken, allowing full-screen viewing of the image as they arrive at the PC. The EOS utility can be configured to open each image as it is received. I’ve set up my PC to open up Adone Bridge CS5 upon receipt of a new image, and we quickly zoom into 100% and scroll around the image to see if it’s ok or not. A full RAW file transfers and opens in Bridge in about 3 seconds. To be honest, I don’t see why anyone would use any of the previous options, when this software comes free with the Camera.
Pros: Cheap, fast.
Cons: Cable permanently attached from camera to PC.
This is a cheap method of wireless tethering. The Eye-Fi is a SD card that has embedded Wifi functionality, and can be configured to send all files written to the card to an external PC. By inserting this SD card into a SD to Compact Flash adapter, some success has been had in using one of these devices in some cameras. The pro’s and con’s are based on the assumption that it does actually work, but currently, these cards are not supported on Compact Flash based cameras, according to the eye.fi website.
Pros: Full wireless tethering, no bulky cables. Cheaper than a WFT-E4 (covered in next section)
Cons: Limited range due to SD-CF adapter, Slow (30-60 seconds for each raw file to get to the PC). Not supported on CF based cameras.
5. Canon WFT-E4 Wireless Grip
The Pros choice. Full wireless tethering with a range of extra options. Full raws transferred in about 15 seconds. There are two versions, with the mark II version having extra features. Both are compatible with the Canon EOS 5D Mark II. It can also be configured to transfer only the JPEG files, so if you set the camera to capure small JPEGS, they should transfer in about a second, or a medium JPEG in a few seconds. It’s about 1.5MB/sec transfer rate over an optimal WiFi connection.
Pros: Full wireless tethering, allows JPEG only option, files stored on card as well as PC. Also functions as a grip, with shutter button, etc. USB connection for external drive.
Cons: Price, about €500 -€900 depending on model.
Conclusions USB tethered using the EOS Utility is my current preferred option, as I can’t justify spending €500 on a WFT-E4, and certainly not €900 on a WFT-E4 II. And in the situations where I need to do real-time previewing of images, I can usually get away with a long USB cable attached to my camera. Where I can’t use a cable, I’m stuck with the swapping of the cards, until I splash out and get me a WFT-E4. Oh, and I’ve an iPad on order, which I’ll have in a few weeks, so I’ll be looking into a reasonably cheap way to preview images on that once I get it.

Well, the evenings are getting longer, and sun is setting around 6:25 these days. With this in mind, I had a quick drive up to the Clare coast to see what kind of time I’d have on the coast to grab a few shots before going home for my dinner. I left work at 5:25, and by 6:15 I was parking at the beach near Quilty. The sun was just about to go down behind a bank of clouds, but I managed to grab this shot before it disappeared completely.
Shortly thereafter, the sun was no longer visible, but I was quite happy to have got at least one keeper. I stayed on for another 40 minutes or so, and took various shots in the area, but alas, nothing of note really. Still, the days are only getting longer, and each evening will give me a few more minutes before sunset, allowing me more time to stroll around looking for a decent composition.
Here’s looking forward to longer evenings!
I just got the following great news. Mark H. McCormick-Goodhart, Director of the ink longevity research programme at http://www.aardenburg-imaging.com/news.html has just announced that the subscription fees to the website are being dropped, making all the research available to everyone for free. I’ve been a member since the very early days, and found in invaluable as a printer in selecting (or ignoring) third party inks for use in my printers.
I’m actually in the proud position of having the WORST EVER performing sample in that programme. An Ink I played around with in the early days was a dye ink off eBay called “Signal Inkjet”. I got one batch of 600ml (6x100m bottles), which cost me $10. It seemed ridiculously cheap, and sure enough, the results matched the price. The prints were only good for a few months before visible fading and colour shifting kicked in. Once I saw the results coming out of Aardenburg-Imaging, I quickly switched back to Claria OEM inks (I was on a dye printer at the time) which was showing much better results.
I eventually got and Epson R2880, and as a result of this research, I settled on Inkjetfly inks, as they have longevity and colour gamut approaching that of OEM inks for a fraction of the price. I’m printing all of my on photos now (and also for some friends, club competitions, etc.) and we’re very happy with the results.
Also, if you’re interested in the research, you can also submit your own samples. It’s very interesting to see your own samples put through the light-fade tests, and you can be confident that the results are accurate and measured in a way that can be compared consistently with the other samples under test.
Have a look at Mark’s website, and take a look at the longevity test results. It lists a huge amount of printer/paper/ink combinations, invaluable for someone who’s looking to use third party inks at either an amateur or professional level.
I’d been hearing good things about various types of battery packs recently, quantum, etc. Being the diy enthuasist (cheapskate) that I am, I thought that I’d research building an external battery pack for my strobes. These usually take the form of a 12v battery pack which connects into the external port of the flash (Canon’s, in my case), reducing recycle time, and giving longer battery life, depending on the type of battery used. I looked initially at the Canon pack, which takes 6 AA batteries. These come in at well over €100. I had a look around on Flickr and other sources, but nowhere could I find a circuit that would feed this external port on my Canon flashes.
Anyway, I had a look on eBay for some canon knock-offs, and I spotted an “iShoot” model for €23 (incl shipping from Hong Kong), which takes 8 AA batteries, so I ordered one. It duly arrived, but unfortunately it was DOA. The LED on the unit would not illuminate, and I saw no change in the recharge time of the flash. I contacted the seller, and he was really great about it. He said that the shipping back to Hong Kong was quite expensive, so I could keep the faulty unit, and he would ship me out a replacement. That arrived about a week later.
Better this time. Upon plugging it in to the flash, and powering the flash on, the LED lit up on the battery pack. With fully charged NiMH AA’s, I was now getting recycle times of just under 3 seconds with the flash set to full power.
I had a look at the internals of the faulty unit, and with the complexity of the circuit board I was looking at, there was no way I would be able to replicate that in a DIY fashion. So the easiest thing for me to do was to just simply order one pack for each of my flashes. At €23, that’s not too expensive, and certainly a lot cheaper than the Canon units. I used this unit over the weekend, and popped off several hundred shots at 1/4 power, and was still getting very fast recycle times. I’m definitely going to order more of these units for my next strobist shoot.
I’ve been using ViewRanger on my smartphone for about a year now. ViewRanger is a GPS application that allows you to download maps onto your phone, and then use them to plan trips, guide you around an area, all the usual stuff you do with a GPS. The nice thing about ViewRanger is that they’ve licenced the maps from Ordinance Survey Ireland (OSI), so you can get the 50000:1 (Discovery series) in a variety of delivery options. I initially bought the app and a “tile pack” for about €20, which lets you download small portions of Ireland on-demand. This is very handy when you’re planning a trip to a particular area, in that you can download the tiles for the area ahead of time. However, if you want to be completely flexible, you can get all 26 counties of Ireland for €150, and Northern Ireland for a further £40. This has the added advantage that when you’re out and about, you don’t need to download any data over the 3G connection, saving you data charges, and works well in remote areas where there’s no data connection available. I got the 26 counties recently, which came in a 1.1GB zip file. Uploading to the phone was a breeze, and once the registration key was entered I could zoom into anywhere in the 26 counties with 50000:1 detail.
The maps, as everyone who’s ever used a Discovery Series map knows, contains a tremendous amount of detail. They have all the contours, roads, Holy Wells, Promontory Forts, etc etc. Also, all the back roads that you’d ever need to get as close to the coast as possible if you’re into coastal landscape photography. Some of the roads shown are so small as to not be drivable. To have this level of detail available on your phone is a great aid to the Irish Landscape Photographer. I’ve found some great new areas (new to me, anyway) using ViewRanger. It’s also great to use in conjunction with The Photographers Ephemeris (TPE) to plan sunrise and sunset trips, as TPE uses Google Maps which requires a 3G connection and does not have the detail contained in the OSI 50000:1 maps. I’ll probably do a small article on TPE as a follow-up to this, as it’s another very handy tool for photographers.
If you order ViewRanger for the iPhone, you need to go through the app store, which will cost you €20, but that comes with a pack of tiles for the country of your choice. For other phones, the app is free, but you pay seperately for the map packs. Tile packs are about €20, individual provinces are about st£60, Northern Ireland is about st£40, and WholeEire.zip will cost you st£120 (€150).
I initially started using ViewRanger on a SonyEricsson Satio touchscreen smartphone, but then got and iPhone 4. ViewRanger support were very quick in helping me move my licences from the Satio to the iPhone at no extra charge.

There’s a very handy feature of the Epson R2880 printer that I only discovered in the last few months, and it’s been great when it comes to cleaning the heads before making an important print, and ensuring all of the nozzles are getting a good ink supply. I put this little blog article together because I was using the printer for about a year before I discovered it (I know, it pays to read the manual), and I thought that it might be worth mentioning just in case anyone out there might find it useful also. It’s probably available in a good few of the Epson printer range.
The printer head is made up of an array of tiny nozzles, split into one array for each colour. In the R2880, there are 8 colours, each colour having an array of about 180 nozzles. That makes a total of 1440 nozzles in the print head! That’s a lot of nozzles, and a lot of chances to get a dodgy print!
Anyway, the auto-check-and-clean function is in the printer dialog screen:
By clicking on the top left icon “Auto Nozzle Check and Cleaning(C)”, the printer will start printing out a check grid, and will then read back what it’s printed to ensure that all nozzles are printing as expected. The following is the resulting output of the auto clean process. (Click on the image to see a bigger version).
Oh, an it’s advisable to insert a good paper for this, such as a glossy paper. It gives better contrast than plain paper, making it easier for the printer to read back the test patterns it’s just printed.
So, in the test page above, the printer prints the first 4 colours. Then it reads back the patern. Becuse there’s a couple of missing blocks in the Light Black array (right side of area marked Pass 1), it runs a clean cycle. Once that clean cycle is complete, it’ll print that pattern again and re-check. If that’s ok, it’ll then print the second 4 colours (Marked as Pass 2). It then sees that Cyan is missing a few blocks in the pattern, so it runs the cleaning cycle again. For Pass three, you’ll notice that it prints the first 4 colours again, then the second 4 colours. This is because the clean cycle may have affected some nozzles in the 1st 4 colours, to it needs to be sure that these are still working ok. For pass 3, you can see that ALL the Cyan nozzles are now lacking ink. So it cleans again. Finally, on pass 4, everything checks out, and the process completes successfully.
I’ve found that it may take doing this process twice, but it’s usually a lot easier than doing a manual nozzle check and clean repeatedly. Also, I suspect that when it’s charging the nozzles, it may only charge the colour that’s Missing ink rather than all colours, thereby wasting ink, but that’s only a theory.
From reading this blog, you might get the idea that I’m obsessed with disk speeds as of late (on the cheap, I might add). Well, you’re not wrong there. And to add to my obsession, I got my hands on a USB 3.0 PCIExpress card and a SATA-USB 3.0 atapter today. After installing the drivers for the card, I then attached a SATA hard drive to the adapter, and plugged it into the PC. Up it came no problem, so the first thing I did was to run ATTO Disk benchmark tool against the drive. Here are the results:
Sustained 80-85MB/sec read/write. It sure beats the hell out of USB2.0, at about 25-30MB/sec. I don’t have a decent drive available to test it faster, but theoreticaly USB3.0 is good to >400MB/sec.
Next purchase will probably be a USB3.0 Compact Flash reader, but they’re very thin on the ground. Oh, and some good and fast Compact Flash cards to go along with it. :)
I got a new motherboard, which has USB 3.0 built in, and this week Aldi were doing a special on USB 3.0 1TB drives for €79.99. I got one, and the following is the ATTO benchmark results:
While I was out recently with my 5DMkII, Manfrotto 458b tripod with 486RC2 ball-head, I noticed that the strong wind was shaking the camera a lot. I looked a bit closer at the setup and it seemed to me that the weak point in the above setup was not any of the parts mentioned, but the 3rd party battery grip I was using on the camera. It’s not the offical Canon battery grip, buta cheap alternative I got of EBay for about €50. When the lens (24-70L) caught the wind, I could see it shaking up and down. The camera body seemed solid, and the tripod head was barely moving, but there was still a shake visible at the end of the lens. It looked to me like the weak point was the battery grip. So, the next time I went out, I took off the battery grip, and screwed the tripod plate back onto the camera and left the battery grip at home. In similar conditions, I could hardly see the lens shake at all this time. Less camera shake, as we all know, means sharper images, and I was much happier with the images from the second outing. Looking closer at the battery grip, it seems solid enough, but when I grab each end and twist, I can see the plastic deform slightly. So the force of the weight of the camera when on the grip, then on the tripod was enough to warp the grip slightly to allow the shake.
Next time I’m in the camera store, I’ll check out the official Canon grip. I’m sure that’s made from much sturdier stuff than the cheap knock-off alternatives…
So from now on, when I go shooting landscape, the battery grip will stay at home.
I had a walkabout around Limerick the other evening. John Hickey (another local photographer) and myself took a stroll around to see what we could see. The light was wonderful, so just about sunset we went into the Strand Hotel and asked at reception if we could go up to the top floor. Thanks to the very nice person on reception, who checked with the boss in the back room and up we headed.
As the sun went down there was a lovely colour to the sky over Thomond Park, the local rugby grounds.
A while later, once the sun had gone down, we move to the other side of the building, and I set up my tripod on the very edge of the balcony, and took a series of five long-exposure images (about 15 seconds each). Stitched in PhotoshopCS5, and the GuyGowan retouch action applied (Yes, I subscribed to the website), plus a few more retouches from myself . I like to call this one “King John’s to the Clarion”, which covers about 800 years of Limerick history. This is the result:
This is best viewed large.
Overall I think it was quite a productive evening.
