Hello,

I would like realise a mosaic with picture do with two devices :
- Fujifilm F10 -> 6Mpx -> 2848x2136 -> 4/3
- Canon 50D -> 15Mpx -> 4752x3168 -> 3/2 (with pictures is in RAW format : CR2)

What is the better way to do this ???
Use the standard or the DSLR version ?
Convert all my CR2 in Jpeg (I have 3000 pictures -> I my god) ?
AndreaMosaic crop the bad ratio or deform the bad ratio ?

Regards

Sorry for my bad english, I'm french.

Try both! Then print the resulting mosaic that you like most. The difference between 4:3 and 3:2 isn't so big. The tiles are cropped.
Yes, you must convert all CR2 to JPG, I like to use Adobe Lightroom (it does it in a Batch), you can also use the freeware Faststone Image Viewer (also with Batch feature).

Thank you for your reply.

I use yet Faststone Viewer to do some test to crop and convert my picture.

Other questions :
1 - I can use the same collection in Standard and DSLR version ?
2 - Do you know what is the resolution that a "Photo Store" could print (600dpi, 1200 dpi, ...) ?

I would like know this to adapt the resolution of my file of the technical possibilities of the print boutique.

The AndreaMosaic collection file (AMC, AM9 and other extensions) is different for each of the four versions of AndreaMosaic. But you can create four collections, one of each version, containing the same files and folders.

A resolution of 200 PPI is already good enough for a quality print. Over 300 PPI is really unnecessary.

There is a difference between DPI and PPI. The basic fact is that DPI (Dot Per Inch) is not a standard unit because the quality and meaning of a "Dot" changes with the device you are printing/viewing. Originally DPI was used for matrix and inkjet printers, later adapter to laser printers too. With these kind of printers, to print one single color (pixel with 16 milion possible values) you need several dots, usually at least 6. On a monitor, based on 3 values (Red, Green and Blue component) to create a pixel a Dot can be interpreted as one of these components (so you need 3 Dots to make one color/pixel) but sometimes a monitor Dot can be interpreted also as one pixel.

So I personally use only the PPI unit (Pixel Per Inch) based on standard color pixels (16 million possible colors for each pixel) without any viable interpretations and marketing deformations.

Thank you for your answer.
