This post is about something that bothers me a lot. Especially, because it originates from a place where you think they should know better. It's about Dots-Per-Inch (DPI) and JPEG (the popular digital image/photo format).
It all starts, when I read the requirements of certain online photo contests. The criteria for entering the contest contain the following: The photo entering the contest must be in JPEG with maximum quality (least compression), AND 300 DPI.
A couple of months ago, Fuji released a highly anticipated firmware version featuring several new functions for the Fujifilm X-T1 digital camera. One of those being an electronic shutter mode.
The original mechanical shutter gives you a or minimum shutter speed of 1/4000second. This is not that fast, compared to the average dSLR, where 1/8000 second seems to be the standard. Another 'problem' is that you can't use fast lenses (f/1.2, f1/4) in (bright) daylight, without the use of ND-filters.
Two weeks ago, we went to Jordan for our holiday. Something we had planned to do a couple of years ago, but was postponed a couple of times due to the events (Arab Spring) in the Middle-East. Something that turned out to be completely unnecessary.
Jordan is a stable (semi) democratic Middle-Eastern kingdom surrounded by some of the most dangerous countries in the region. Especially with the rise of the Islamic State (IS) in Syria and Iraq which share a border with Jordan on the north/east, things COULD turn ugly relatively fast... But then again, were are you 100% safe?
You can also be shot from the skies over the Ukraine while going on holiday (MH17), or your train can be blown up in a train station in Madrid, or spotting planes on the World Trade Centre (Twin Towers) can result in death and mayhem. While staying at home is also not without risks. How many people die in the bathroom by slipping over a couple of drops of water?
So more than enough reasons not to stay at home and taste the culture of Jordan during an 8 day trip.
A while back I investigated the possibility of using the Lee filter system on my Fujifilm X-T1. As you can see, I invested in two Lee ND filters;
- Lee Big Stopper (110ND / 10 stops Neutral Density Grey filter)
- Lee Little Stopper (106ND / 6 stops Neutral Density Grey filter)
The thing with ND filters is that they reduce the light evenly. This results in (depending on the greyness of the filter) longer exposure times. With enough 'stops' in front of your lens, you can stretch the exposure from 1/200s to 10 or 15 minutes. Shooting with exposure times of minutes instead of the usual fraction of seconds results in motion blur in the photos (assuming that you're not shooting a stationary object indoors). Expose long enough, and the movement becomes a silky haze.
