What may appear to be ephemeral visions or dreams can now be captured in reality with the Daguerreotype Achromat 2.9/64 Art Lens, inspired by the world’s first photographic optic lens. Seamlessly blurring the lines between fantasy and reality, alternate between razor-sharp details and silky-soft focus with this advanced Art Lens. If you can imagine it, then you can make it with this extraordinary handcrafted art lens. Compatible with both SLR and mirrorless cameras, including Canon EF and Nikon F bodies, as well as many more when using an adapter.

A reinvention of the original 19th century Joseph Petzval portrait lens for modern-day analogue and digital SLR cameras with our first Bokeh Control Ring for even greater experimentation.

Lomography Art Lenses feature the finest glass optics to produce photos that will astonish you with their colors and optical character. As well as being designed and assembled by hand, these lenses have been engineered using modern techniques and multi-coated to produce vibrant, strong, wonderful photos with a whole range of contemporary cameras. Each Lomography Art Lens brings with it a wide variety of creative possibilities, no two are the same.

You can use the same PPI formula above to calculate pixels per centimeter, PPcm. Just substitute cm for inches to find PPcm.

Daguerre was the kind of guy who made things happen. In addition to having invented photography – as you do – he also designed and fabricated things like the Diorama, was an accomplished painter and often worked as an extra at the Opéra de Paris too – the hottest 18th-century club in town. To top it all off, he was also well known for his tight-roping skills and nifty moves on the dance floor.

The Daguerreotype Achromat 2.9/64 Art Lens is a revival of a nearly two centuries old lost aesthetic. This aesthetic was courtesy of the world’s first-ever photographic optic lens, invented in 1835. This historic model was built on a unique achromat design that bathed the world’s earliest photographs in a powerful, alluring veil of light.

PPI is a measure of pixel density or resolution of a computer screen, television screen or other display device. Pixels per inch or PPcm indicates how many pixels are in a 1 inch line or 1 cm line on a display. Also calculated are dot pitch, diagonal in pixels and total number in megapixels.

You have a computer screen that is 1920 pixels wide by 1080 pixels high. The diagonal is 10 inches. You want to find the pixel density in one linear inch of display.

In 1835 Charles Chevalier and Louis-Jacques-Mandé Daguerre changed history – they gave the world practical photography. Daguerre combined a Daguerreotype camera with the very first photographic lens in the world, built by Charles Chevalier. The Daguerreotype Camera captured the first-ever picture of a human being, at Boulevard du Temple in Paris, 1838.

Multiply PPI × PPI to get pixels per square inch. The number of pixels in a square inch represents the resolution or pixel density of an area of one square inch. Substitute 1 cm for 1 inch to find pixels per square centimeter or PPcm2.

Charles-Louis Chevalier was a bit more of a technical nerd – the son of a prominent French instrument maker and a leading Parisian optician – he began designing lenses as a teen. He handcrafted the first optic lens in the world after he received an order from Daguerre to use on his Daguerreotype camera. In 1840 Chevalier received the top prize at Paris’ Société d’Encouragement for his discovery.

The number of pixels per inch or PPI tells you how many pixels are in a 1 inch line on a display screen. The PPI will be the same whether it's a horizontal or vertical or diagonal inch because pixels are square and therefore symmetric. If a display does not have square pixels then this calculator does not apply.

The Daguerreotype Achromat 2.9/64 Art Lens optical construction has been redesigned to allow both ethereal soft focus from apertures below f/4, or razor-sharp results with deep contrasts from f/5.6 onwards. Asides from the classic Waterhouse Aperture plates, for this lens, Lomography has created the Lumière and Aquarelle Aperture plates. The Lumière aperture plates soak images in a radiant, soft glow – and create delicate dotted backgrounds, enriching depth of field. The Aquarelle aperture plates produce a rich and very textured, painterly effect – comparable to watercolor masterworks!

The Daguerreotype camera complete with the Chevalier lens was publicly announced on 19 August 1839, when the French government presented its patent as a gift “free to the world” and 1839 has been heralded as the year in which photography was born ever since.

For example, let's say you have a screen width equal to 1920 pixels and height equal to 1080 pixels. The ratio of width to height is 1920:1080. To reduce this to lowest terms we find the greatest common factor of 1920 and 1080 which is GCF(1920,1080) = 120. Reduce our ratio of 1920:1080 by dividing both terms by the GCF of 120. 1920/120 = 16 and 1080/120 = 9 so our reduced ratio is 1920:1080 = 16:9. 16:9 is the aspect ratio, the ratio of width to height in lowest terms.

In some cases we want to know the aspect ratio in terms of 1 as the second term. In that case, divide both terms by the second term to get 1920/1080 = 1.7 and 1080/1080 = 1. The aspect ratio in terms of 1 is 1.7:1 and we can say 1920:1080 = 16:9 = 1.7:1

Diagonal dot pitch is the diagonal distance from the center of one pixel to the center of the next. Dot pitch is calculated from the diagonal length in inches and pixels then converted from inches per pixel to millimeters per pixel but normally only expressed in millimeters (mm).

The PPI Calculator finds pixels per inch (PPI) and pixels per centimeter (PPcm). It will calculate PPI when inches are entered and calculate both PPI and PPcm when centimeters are entered.

Amazing aperture adventures await with an optical construction redesigned to allow both ethereal soft focus from apertures below f/4, or razor-sharp results with deep contrasts from f/5.6 onwards.
