SIGMA QUATTRO CAMERAS
The big update this month, if one excludes the PhotoShop Beta, was that I obtained an unused Sigma DP3 Quattro at a really good price. I already own a DP1 but have been unable to obtain the DP0 or the DP2. I should mention that I also use a Sigma DP3 Merrill.
The Sigma dp0 Quattro is a discontinued[ fixed-focal length APS-C digital point-and-shoot camera, announced by Sigma on February 10, 2015.
Like other cameras in the dp Quattro series,it features a 29-megapixel Foveon X3 sensor, but is said to produce images equivalent to that of a 39-megapixel bayer sensor camera.
The dp0 Quattro has the widest focal length compared to other models of the dp Quattro range, with a 35 mm equivalent focal length of 21mm.
PCMag called the dp0 Quattro a "niche product", due to its fixed wide angle lens, with some quirks such as its uncommon grip shape, slow processing and writing per capture and battery life, but praised it for the quality of images produced, with its superior sensor and lens, giving the dp0 Quattro a rating of 3.5 out of 5.
During the CP+ [jp] show held in 2015, USA Today did a first impressions review of the dp0 Quattro, which mentioned that the improved sensor on the dp0 Quattro had "faster processing times", compared to older Foveon-based cameras, but still pales in speed compared to other cameras in the market at that time. The camera is described with low lens distortion despite its wide angle lens but with poor battery life, with a conclusion that the camera is "an endearingly oddball".
The operation of the Foveon X3 sensor is different from that of the Bayer filter image sensor, which is more commonly used in digital cameras. In the Bayer sensor, each photosite in the array consists of a single light sensor (either CMOS or CCD) that, as a result of filtration, is exposed to only one of the three primary colours: red, green, or blue. Constructing a full-color image from a Bayer sensor requires demosaicing, an interpolative process in which the output pixel associated with each photosite is assigned an RGB value based in part on the level of red, green, and blue reported by those photosites adjacent to it. However, the Foveon X3 sensor creates its RGB colour output for each photosite by combining the outputs of each of the stacked photodiodes at each of its photosites. This operational difference results in several significant consequences.
Because demosaicing is not required for the Foveon X3 sensor to produce a full-colour image, the colour artifacts ("coloured jaggies") associated with the process are not seen. The separate anti-aliasing filter commonly used to mitigate those artifacts in a Bayer sensor is not required; this is because little aliasing occurs when the photodiodes for each colour, with the assistance of the microlenses, integrate the optical image over a region almost as big as the spacing of sensors for that colour. On the other hand, the method of colour separation by silicon penetration depth gives more cross-contamination between colour layers, meaning more issues with colour accuracy.

MEDIATEMPLE TO GODADDY MAY 2023
Within a few months all my sites will be self hosted and while that does present many problems I can say, based on experience, that shared hosting and even dedicated WP hosting is, at best, unreliable. For a number of years I used MediaTemple and while I may not have been over impressed by the quality of service I was reasonable happy. However, MediaTemple was purchased by GoDaddy and my sites were transitioned this week and I am less than pleased.
However, to be fair, the site OSX128.COM which is now hosted by GoDaddy is faster than any of my self hosted sites ... this is mainly because it is what is known as a 'headless' WordPress site.
I PLAN TO VISIT CORK CITY AND COUNTY
I am planning to spend the second week of May 2023 in Cork City and I have decided that the Sony FX-30 will be my main camera and my backup will be an old Sigma DP1 Quattro which is a bit of a risk. I have yet to decide what lenses to bring with me.
PHOTOGRAPHS OF SIR JOHN ROGERSON'S QUAY IN DUBLINPHOTOGRAPHED USING A SIGMA DP3 QUATTRO
The idea for the railway arose from proposals by the merchants of Dublin to link the city with Dún Laoghaire Harbour, because the levels of silt at Dublin Port meant that large ships could no longer dock there and instead called at Dún Laoghaire. The line ran from Westland Row (Pearse Street) to Seapoint and shortly after was extended to Dún Laoghaire. Blackrock Station opened on 17 December 1834.

SAINT FIN BARRE’S CATHEDRAL IN CORK CITYPHOTOGRAPHED IN MAY 2023
Finbarr was born in about 550. He was, by legend, given Gougane Barra as a place of contemplation, and visited Cork city to lay the foundation stones for the "one true Christian faith".[3] According to tradition, after Finbarr died his remains were brought to Cork to be enclosed in a shrine near the site of today's cathedral.
Archaeological evidence suggests the first site at Fin Barre's probably dates from the 7th century, and consisted of a church and round tower that survived until the 12th century, after which it fell into neglect, or was destroyed during the Norman invasions.
