1. A more in-depth edit
Photos printed in large format require more careful editing. Details that do not stand out in small format will be magnified in printing. Hair on clothes, a strange bird in the sky, electric wires in the landscape. Lots of things that you don't notice when the photos are on the screen, but catch the eye once they are on the wall. Before investing in a large format print, consider ordering a specific retouch for the print or check with your photographer if the files submitted are already optimized for this purpose.
2. Image Calibration
Your photographer (me!) works in RAW or TIFF format, files that you cannot open yourself with basic software. The image processing softwares that I use are the best on the market and always up to date. Files can be encoded to meet your printer's requirements to ensure the best possible color rendering and preserve details.
3. Options, quality and durability
Big box stores rely on volume sales and have limited options. By choosing a professional printer, you will have access to more flexibility. Custom dimensions, printing on canvas, metal, acrylic, anti-reflective glass, pearl, matte or glossy finish... Big box stores also do not have high-resolution printers and quality paper. Therefore, colors and details will not be true to what appears on your screen and the life of your print will not be as long as on papers designed to prevent fading and deterioration.
