Thank you for your time. It is my first post on mu-43 forums. The question I have is can my photograph print to such a large size and still be acceptable? I have never printed anything in my life from a digital camera and would really appreciate your opinion on whether printing this large is a foolish endeavor and also if there better places other than Costco. This photograph was taken with GX7 and I have been shooting RAW with camera settings at sRGB space. I am interested in printing at Costco 60x45 inches split canvas so that the single photograph that I have taken is split into two parts. Costco website: http://www.costcophotocenter.com/Help.aspx#/topic/product-pricing-shipping-costs prices this at $289USD. Costco has recommended resolutions for various print sizes specifically for canvas at http://www.costcophotocenter.com/Help#/topic/product-information---canvas-prints. This Costco website above states that for a 60 X 45 split 2 part canvas, the minimum resolution at 75 dpi requires at "minimum" 4725x3600, and at "optimal" 150 dpi requires 9450x6450. ( I actually don't understand why there are two recommendations. Is it implying that if I send them a lower resolution image they will then print at a lower resolution of 75 dpi whereas if I send them a higher more optimal resolution then they will print at 150 dpi?) my exif data from the image I want to print is as follows: file is a TIF file. ( I started out as a raw file in light room five and then exported it as a TIF file that was edited in Photoshop and then subsequently saved as a TIF file) dimensions 4920X3683 width 4920 pixels height 3683 pixels horizontal and vertical resolution both are at 240 dpi bit depth 48 compression uncompressed resolution unit two color representation SR GB From the resolution of my photograph it seems that it meets the minimum requirement but is far from the optimal requirement. So it is difficult for me to know if I should proceed with this print or if it will be unacceptable and not worth the $298. I would hate to spend this kind of money and not even meet "optimal" results. To be honest I happen to particularly like this photograph and happen to needed decorating piece in the home so it is not like I will be printing large prints that often. In fact probably it will be many years before I will have such an interest in printing this large. Thank you all for your time I want to take this chance to thank many of you for all your various contributions on the forums and I have learned immensely from reading your writings in the last six months when I was first introduced to mu43.
