would appreciate any information on what the default dpi is for this camera - and is it variable>

 

Thanks

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

I think you're talking about resolution (dpi is a term usually used with inkjet printers).

 

The V-Lux-1 has an effective maximum resolution of 10.1 megapixels (3648 x 2736 pixels) and it is variable over three different formats, 4:3, 3:2, and 16:9.

 

Spec sheet should still be available on the Leica website

 

Hope this helps. I find it to be a very capable and handy digicam.

Thank you Henry - appreciate the clarification. I am planning to transfer some photos to CD for printing and wanted to make sure I had the best CDs for resolution. I was speaking with another photgrapher and he asked what the dpi (dots per inch) setting was for the V-Lux. I told him the max resolution was 10.1, but he seemd to think there may be a different setting for the camera - on the whole.

 

Thanks for the help - I am new to the forum

i transferred my images to the computer from the card. i am using 10 megapixel setting (4:3) at fine setting.

the images show up in photoshop at 3648x2736 @ 72 dpi

my smaller cameras with lower megapixels show up with 180 dpi.

is there a way to increase this resolution (or is it just something with photoshop)

The dpi is just a number that tells the printer how big to make the print.

It has nothing whatever to do with image quality from the camera.

You can set it to anything you like in Photoshop etc. to set the actual print size.

Unless you are very critical, values from 150 upwards will give acceptable prints.

hello, from what i know the dpi ARE very important for the quality of the prints.

I work as a photo researcher for a photoagency (i send pics to magazines), the standard for a photo to be published is 300 dpi, 25/30 cm longer side, sometimes 40 for a double page. In Photoshop, go to the IMAGE menu, IMAGE SIZE, change the dpi to 300 (with the Resample Image option unchecked) and see how many cm it gives you on the longer side. If it's less than 25/30 and you had the camera on Fine Setting there's something wrong.

Hope this helps,

good luck

DPI = Dots Per Inch

 

To determine DPI you need to know the pixel size of the image and the output print size. Trying to determine the DPI of a camera without any print size is kind of like asking "how many MPH is it to New York City?" Both are meaningless.

 

To get DPI, divide one side in pixels (3648) by the corresponding print dimension in inches (30). Thus, for a 20x30 print from a 10MP V-Lux 1 file, you would get 121.6 DPI. You'll get higher DPI numbers for smaller prints and lower ones for larger prints.

 

The old belief that you must have 300 DPI to get a good print is not really the case. You can expect quite a good 20x30 print from a 10MP file. Otherwise, according to the 300 DPI myth, you'd only get a good quality 8x12. This is just patently untrue.

 

As far as the Photoshop 72 DPI thing, don't sweat it. This is just the default for files that have no preset output size. Make sure you uncheck "resample image" then set your desired output size. The DPI will change accordingly, but the pixel size will not.

 

Hope this helps.

Thanks David

 

This helps considerably. I have shot numerous pictures through the V-Lux and have had some good success - - DPI is one issue I have wrestled with.

 

Thanks from a newbie on this forum.
