I think the possibilities that DALL-E offers us to try out our ideas, concepts and obtain results that, even if they aren’t exactly what we had in mind - will likely come pretty close to what one had in mind initially, thereby helping us get to the next level.
The one (actually two) drawbacks I find are that the resolution of the images produced, and what we are limited to uploading - are very low - 72 dpi with maximum dimensions being 1024 x 1024. Also, plus the limitation to a square format; with no option for say different heights and widths.
I would surmise the size of resolution and file size and dimension constraints are a function of the amount of computing power it would drain from DALL-E, which is totally understandable.
However, why not, if one is a paying customer and willing to “pay the freight” to order a higher resolution image - say 300 dpi in a larger dimension that you like and feel you can use, make it available?
Why not offer that option to people to allow them to select individual files out of the many that are only close but no cigar that we all know we will generate over time but enable us to take ones, that we feel are marketable and download hi-res versions?
I produce fine art giclée prints on canvas and/or other media and 300 dpi is usually the minimum I like to work with (prefer 360 DPI); my prints usually are around 24 x 24 inches, 36 x 36 or various other dimension. My results are sharp as a tack and riveting - no brag - just fact!
I would be very interested in knowing, if the management team at DALL-E has ever considered offering this upscaling option as a separate, income generating stream? If so, I would be most interested in hearing about it!
To me, it seems like the next logical step to consider.
