This does not mean cropped images are ineligible, just that we are seeking work with its final dimensions after any post processing. To accommodate this, the maximum dimensions in PhotoEntry for this one submission have been set to 9,999 x 9,999 since actual sizes will vary by camera. Only uncropped images from something like a Fuji GFX 100 or stitching from many multiple images will exceed those limits. Even a Sony A7R IV with, by comparison, its paltry 61 MP would be OK.
Unfortunately, PhotoEntry does not cater for flexible image sizes as it is expecting them to be projected. Consequently it gives a warrning that the image is too small. On this occasion only, the warning can be safely ignored. If you can see the image in PhotoEntry, it has been successfully uploaded. The other limitation of which to be aware is that the maximum permitted file size per image is 10 MB. The colour space should be sRGB, which is the usual setting for images uploaded to PhotoEntry for competition.
It has been suggested to me that this explanation could require clarifying, especially as there might be some confusion between the concepts of image pixel dimensions and file size - there is no direct correlation between the two. So let's have another go. Hopefully I will clarify the waters rather than muddy them.
Say, for exanple, that your camera has a 24 MP sensor and image dimensions start out at 6000 x 4000 pixels. After post processing, which might include cropping, the image dimensions could end up being smaller. That is the image which the club is seeking, not necessarily the one straight out of camera unless that is the final version. In many instances, it will not be, especially for those who shoot Raw files which require further processing to create the image. As previously described, PhotoEntry will generate a warning that the image dimensions are too small which in this instance can be ignored.
The other consideration is the file size of the image, which is entirely separate from the image's pixel dimensions. PhotoEntry has an upprer limit of 10 MB which is normally sufficient as an image's pixel dimesions are usually reduced for competition purposes. However, a maximum quality JPEG created using a camera with a large number of megapixels might exceed the threshold. If exporting from Lightroom, in the File Settings section there is an option to specify the maximum file size. Set it to 9000 and ensure that the check box is ticked. Lightroom will sort everything out automatically.
With Photoshop, it will be necessary to adjust the quality setting to create a file of the required size. Start by ensuring that the image is in 8 bit mode and that the Preview option is checked in the "JPEG Options" panel. Photoshop will provide an estimate of the eventual file size. (Note that it only does this for 8 bit images.) If the file size exceeds 10 MB, it will be necessary to lower the Quality setting until the figure drops below 10 MB. Photoshop's estimate is not always accurate and if PhotoEntry rejects the upload for being too large, it will be necessary to resave the image with a Quality setting that has been further reduced and submit the new file to PhotoEntry.
