The What’s Up Docs podcast from the BBC is an entertaining but factual podcast about health presented by two doctors, Chris and Xand van Tulleken (brothers and twins!) who find out to their dismay that they were wrong about the dangers of getting a nice healthy colour from the sun.
A tan occurs when UV radiation damages skin cells, causing them to produce more melanin as a protective response. This process involves DNA damage to skin cells, which can accumulate over time and potentially lead to skin cancer.
Sunburn is obviously harmful and painful. Even one blistering sunburn in childhood can double your lifetime risk of melanoma.
It’s a bit late for my Irish readers, as we had cloudless skies and a hot sun last week. Temperatures reached 25C where I was, so I slapped on the factor 50 sunscreen and made sure I was wearing a hat when I was outside. Many years ago, a neighbour died of skin cancer at the age of 52, only a few years older than I am now.
The Met Éireann UV Index page will show you what the UV index in Ireland is. If it’s 3 or over, you should be covering up with clothing or sunscreen. It’s quite alarming that the difference between a clear sky and a cloudy sky is 1-2 or 8-10 on that index.
A few years ago, I invested in a Godox TT685s flash unit, a TT350s flash unit and X1Ts transmitter for my Sony A7III camera. Despite their potential, I rarely use them, leading to some forgetfulness about configuring their wireless transmitters. A helpful YouTube video brought back memories of the necessary settings, including the requirement that the channels used for communication between devices must match. I also remembered there was an irritating issue about them, but I couldn’t quite recall what it was.
Before a party, I tested the flashes on our Chihuahua, Diego, placing one on the floor and the other on a window sill. Both worked flawlessly, and I was excited to use them that evening. Diego is a very patient subject, sometimes anyay.
My willing test subject, Diego.
Later on, I got my camera out, successfully made a photo or two of one group, then headed to the kitchen. However, while trying to photograph the beautiful desserts there, the flash refused to fire, even after several attempts. I resorted to aperture priority mode with auto ISO, managing to snap a few shots without the flash’s assistance. Despite the hiccups, I was able to capture images.
I went around to different groups to take photos, but to my dismay, the flash wouldn’t fire as expected, leaving me to apologize for my failed attempts. Fortunately, after numerous attempts, the flash worked, but the experience was disconcerting. Eventually, I resorted to attaching the flash to the camera and was relieved when it worked perfectly. Because of the complications, I was grateful to have captured some memorable shots.
While troubleshooting why my Godox TT685s flash didn’t fire, I scoured the internet for answers. Amidst various suggestions, I stumbled upon a StackExchange post that revealed the true reason behind the problem: the Godox X1Ts transmitter and the TT685s flash were positioned too closely to each other. I remembered it was the same vexing issue that had slipped my mind earlier!
Godox added a “close mode” to their transmitters to address the issue of the X1Ts transmitter and the TT685s flash being too close to each other. While it’s unclear to me why this would affect radio signals, it’s good to know there’s a solution. A firmware update may be needed for the X1Ts, but my device has the latest one (v18). To activate this feature, hold down the TEST button while powering on the transmitter until the status light blinks for 2 seconds. The setting will reset when the device is turned off. After trying this out, I can confirm that it worked flawlessly.
I don’t use flashes much. In the future, if I encounter that same non-firing issue with my Godox X1Ts transmitter and TT685s flash, I hope I’ll remember to check my own blog first to avoid the hassle of researching it elsewhere. Hopefully, my own documentation will come in handy and save me time in the long run!
One of the Facebook groups I’m part of is Sony a7iii/a7riii setup Tips. It’s a relatively quiet group but it’s chock full of great tips for Sony’s latest cameras. One of those tips was posted yesterday and Daniel Ockeloen, the group administrator, made a video of it which I have embedded above.
In manual mode, the AEL button can be used to maintain the exposure while you change settings. With AEL activated changing the shutter speed will change the aperture and vice versa. In effect it’s the same as going back to Aperture or Shutter Priority modes but it does allow more flexibility since AEL can be deactivated and you get full manual control again, with the same exposure.
Do other cameras do this? My Canon 6D doesn’t. Apparently Pentax cameras have a hyper-manual mode which operates in much the same way, but others have been saying for a long time that manual mode is manual mode and you don’t need auto exposure.
