This is some blog description about this site
I have decided to write some more information on the subject of old photos restoration for printing on canvas. This is something that we do more and more and I feel it maybe of interesting for many people.
I love to work with old photos, there is something very special about them, either old negatives, slides or simply old photos. With the negatives it is like revealing hidden beauty, likewise slides - I have experienced very emotional moments once they have been scanned and presented to owners who didin't really remember what exactly was on them. Obviously scanner plays extremely important role in capturing the data. This is why we proudly use high tech Screen Cezanne Elite scanner which is doing just that - making sure that none of the details are lost. As photos do usually need quite a lot of work to be done before they can be printed on canvas it is important to have a good starting point. For a start we scan at 16bits - not very many scanners can do that. In simple terms 16 bit is allowing a lot more information - tonal range - to be captured. In 8 bit mode (most commonly used by domestic scanners) you can only capture half of the existing tonal information. This plays huge role when it comes to keeping the details sharp and also when the photo need to be magnified. This is almost always the case. Another important aspect is relosution. Canvas prints do allow to use lower resolution than when printing on paper. Yet once we increase, double, triple or even make the originals more than 10 times bigger resolution plays its role. Our scanner can scan up to 5300 dpi. This is true optical resolution. Scanning resolution has to be adjusted specifically to each job - there are no benefits to use too high resolution - quite contrary - the image will loose it's sharpness and lack detail. Surprisinlgy new domestic scanners are becoming better. There are differencies though which separate them from high end scanners. Apart from lack of 16bit capability there is also sensitivity in dark tones. This is where the difference is quite staggering. Home scanners will loose the differentiation even above 90% of black, simply showing anything between 90%-100% as 100% black. Now, if your photo has a lot of details above this 90% threshold - they will be simply lost. The key to a good looking canvas prints is a good contrast and full tonal range. This is why we have decided to offer all our customers free scanning service using our Screen Cezanne Elite scanner, with any order. Your originals will be returned to you together with your canvas prints. We can also send digital files of the scans. Please contact us if you require any more information on that.
