Auctiva will resize any upload to maximum of either 1024 pix wide or 768 pix high for storage and use for supersize, so cropping and sizing the picture prior to upload with either dimension restriction in mind will provide the best supersize. Uploading smaller doesn't get a resize (no loss). However, uploading very large (high density) takes time or often fails to upload. So, I look for balance between size and limits.
I frequently use the 6.1 MP setting on my camera for close-ups that I intend to crop for small detail on an item (like coins). For full-frame shots with no crop (or limited crop), I use 1.7 MP. My cam has 4:3 aspect (like most) and maintains the 1024 x 768 perfectly for landscape mode shots.
Thanks, Danno. From the other thread I got an understanding of how the Auctiva image uploading process works, and now I see that you tend to adjust the megapixel size for close-ups.
Maybe I'm having trouble understanding how the sizing relates to the resolution. If I upload an image at 1024 x 768 and the resolution is 300, then it will show more detail in the supersize, is that correct? (vs. 1024 x 768 at 72 resolution)
I'm having some trouble getting all my images to appear in uniform size and then to get good detail on the supersize. My next step was going to be to leave the images at the pixel size they are full-size from the camera (which corresponds to the 4:3 ratio) and but make the resolution high. When it comes to cropping, I guess the high res is important but also, to keep sizes uniform, it's important to crop to a 4:3 ratio?
Sorry to be so dense with this. I use Photoshop for image editing and so theoretically I have a lot of options. Thank you.
The 1024 x 768 is "pixels", which dictates how it will display on a pixel based monitor. Digital cameras also operate on pixel for capture, e.g. 6.1 Megapixel translates to highest resolution for my camera.
When I crop, I'm not loosing resolution, i.e. I'm not losing density. When I resize (or let Auctiva resize), resolution is lost by forcing less detail per pixel retained.
An ungraded coin does well as square, which means the height limitation of 768 pixels is in play. I do close-ups at 6.1 MP or my scanner at 1200 DPI, crop-in to get the coin with small amount of boarder/background and upload the result, allowing Auctiva to resize. Keeping common aspect ratio or crop to specific size (like 8 x 10) can usually keep them uniform, but it also depends on how you want images displayed in a listing for best viewing of item. There's no absolutes, just best fits for the occasion.
Here's one from my photo/scan library that's stored on my PC at 2064 W x 2055 H (nearly square) and resized 771 W x 767 H for supersize by Auctiva at upload. The full-size limits are 400 W x 300 H for storage and display.
Edit: I added the thumbnail (limit 80 x 80), so you could see the set stored by Auctiva (minus store at 96 x 96).
