I have been using ProDPI for my printing needs for several years. Although I really don't have any issues with their work, I find that their software for uploading my images is cumbersome. Also, they require that my uploaded images be sent as a JPEG in sRGB colorspace. I don't know whether this in any way compromises the final print (compared to sending a TIFF in Adobe RGB). So I guess that this is my excuse to get a sense of which other labs I might consider. If anyone has any strong recommendations based on their experience with other labs, I would truly appreciate your input. Thank you kindly.
