Some of my tools

Just a quick note about a couple of tools that I use in my photography process.

As part of my backup process I record my photos on DVDs. I don't like simplified consumer version of Nero software that came with my DVD writer, so I tried some free tools. I tried several of them which I didn't like - some for uncomfortable interface (e.g. many clicks needed to add a folder to a disk); some failed during recording (which I wouldn't expect to happen at all these days with mature technology). Finally I chosen imgburn that I prefer over the others: http://www.imgburn.com - reasonable interface; some advanced features, and good reliability.

The other tool that I use often is FTP client. Again I tried several options and for the last year I use Filezilla: http://filezilla-project.org, which I know also recommended by many other users.

Good time to photograph tulips

It's great time to photograph tulips now while they are blooming. It's a long weekend in Belgium and in neighbor countries and the weather is nice. A good place to go is Keukenhof in Netherlands, not far from Hague. Thousands of tulips of all different sorts and colors, and many other flowers.

Trying macro photography

I've tried macro photography with Canon EF 85mm f1.8 lens having +4 lens attached; and with old manual Russian-made Helios-44 lens + cheap Chinese extension ring.

The option with EF 85mm and +4 lens means full electronic control with autofocus.

Cheap extension ring is a piece of metal only, no electronic connection between camera and lens. This is why I used old Helios-44 - because it has manual aperture control.

The result with EF85 is in general good, but chromatic aberrations are strong on contrasty edges (depending on particular scene of course).

Helios-44 resulted much less CA however the transition between area in focus and completely unsharp part isn't very pleasant to my eye. EF85 produces a softer blur.

I must note however that the comparison isn't fair because I tried 2 lens in different conditions. Now as I noticed some interesting point I'll need to find some time to make a real comparison.

Testing CF cards transfer speed with Transcend and Hama card readers

A few days ago I became a happy owner of new Canon EOS 5D Mark II camera. Thus I decided to buy a larger compact flash card. I wanted 32GB with a good speed. However the price of top-range brand name cards seemed a bit too high so I decided to make a compromise - i.e. to get large capacity and reasonable speed, but not the fastest possible.

I bought Silicon Power 200x card and I got interesting results testing data transfer speed.
3_flash_cards

I did a basic test on my PC, using USB card reader. My older cards shown on the picture are rated 100x (PQI) and 133x (Transcend). They both demonstrate read speed of about 40 MB/s (reading large file from card to hard drive of my PC). However the card from Silicon Power has only shown 16 MB/s in my initial test with Transcend M5 card reader. I repeated the test few times with the same result. At first I was very disappointed, but when I repeated my tests with Hama card reader I've got the speed of ~44 MB/s from the same card!

The writing speed is approximately the same for Silicon Power and for 133x Transcend and is about 9 MB/s (100x PQI is notably slower).

I paid about 70 Eur for the Silicon Power card while the brand name 266x-300x cards are priced above 150 Eur, so I am very happy now with the saving I got :)

My main surprise is that cheap Hama reader overperformed the Transcend by so much - but only on 32GB card. The tests with 8GB and 2 GB cards didn't show a difference between 2 card readers. FYI Hama reader is a box from blue transparent plastic and called 'Cardreader 19 in 1'. It has partnumber 00055114. I've got one in Germany for 9 or 10 Euro. (The one from Transcend looks nicer - it's a square white glossy box in "Mac-style" but it failed miserably with large card.)

Finding photo models

There are several ways to find models. Relatives and friends might be easy to access, but they are not necessarily good models. Another possibility is to use special web sites where models and photographers find each other. Make-up artists can be found the same way.

Quite often the same model can be found on different sites at the same time. Sites provide different options and different communication channels to the users.

Probably the most popular in Belgium is http://modellennet.be. Currently it lists more than 2000 models (mostly from Belgium and some from the Netherlands). In Dutch.

Another popular site is http://www.eye-on.net (former photograaf.be). Current list is above 800 models. The site is in Dutch. It is supposed to grow beyond a basic meeting place for photographers and models, but these services are yet to be developed.

Less popular is http://models.handelsgids.be/?zoekenHome/

Speaking about Dutch model the most popular site is http://DutchHeaven.nl

Very popular international site: http://www.modelmayhem.com. It is not so popular in Belgium (only 300 models) as it is in some other countries, but is it a good resource for photographers. The site is in English.

Site popular in Germany: http://www.model-kartei.de. It lists more than 20,000 models, and on top many make-up artists, studios for hire, etc. Although the site is in German it is quite easy to search for models if you learn a few basic words.
