Choosing Image Resolution and Scaling, Series and A/B Comparison
The diglloyd.com publications often include images as series (aperture series, comparative series or similar) and/or as two A/B images.
Quick tips (details follow), referring to the screen shot below:
- Choose the desired resolution at top (numbers indicate width in pixels).
- At bottom, control which variant is shown (an f-stop in this example)
- At bottom, control the scaling (Resize). On conventional displays, this should be 100%, but on Retina or HiDPI screens at 2:1 it should be 50%.
- Any two images can be compared/toggled with the A-B mode.
On the gallery page for each image (the window that displays the image by itself), various controls are found at bottom.
Series vs A-B mode
By default, an image series (aperture series or other) allows rapid mouse-over, which yields an animation of sorts, which is very helpful for seeing how lens rendition changes with aperture or focus and/or for quick flipping between lenses and apertures. On touch devices (phones and tablets), touch each aperture in turn.
As shown, the image series is being shown (Series mode). Choosing A-B mode allows a simple two-way toggle between any two images and is an excellent way to compare changes, for example, between apertures.
