Original aspect means the same ratio of length to side - so a 4x6 = 8x12 = 2x3 etc.
I've done the corrections for color, WB, noise....I've done cropping, but in Aperture I was doing it with 'retain original aspect'....
I don't know what that original aspect is...hence, my asking.
I'm wanting to know if I want 4x6 prints, if I need to go back to all my images and re-crop them before sending them out...or if the 'native' export from the 5D3 happens to be 4x6...?
Conversely you would not be maintaining the aspect ratio if you cropped to e.g. a square image.
The sensor size is nominally 24mmx36mm or 2:3 - so the same as 4x6.
Nothing should be lost on a 4x6. Othersizes such as 5x7, 8x10 etc. will cause some cropping.
I am not familiar with aperture to know if it supports print sizes, but I expect that it does.
As for format - that will depend on the lab. JPG should be OK for 4x6 etc. For larger prints a TIFF maybe better.
IF these are your first prints you may want a lab that will perform some work on the image - e.g brightness control, as you may otherwise find that your images come out too dark due to you having too bright a monitor.
Further on you may want to see if the lab has ICC profiles for download - this will help in getting more accurate colours.
To start with though I would just send in a number of images in JPG at 4x6 and see what comes out.
You can always learn and improve / change labs later...
That's what I was looking for....the 5D3 sensor size/image size.....so, I'll know to go iterations off 2x3....
I've noticed no one here has mentioned snapfish...which was the first one to come up on my first google search....anyone have experience with them?
