Windows freeware to lock in a 3: or 4:3 aspect ratio for cropping

That's true for lossless. But the cropping itself is always destructive.

no it isn't.

You misunderstood. If you crop an image to keep only the left side, the
right ride of the image will be gone. Meaning that the crop function itself
removes data. Whether there's an undo or redo functionality or not, that an
entire different function.


bmp is obsolete.

In a Mac OS, BMP isn't even the native image container. So, I would be
obvious that most, if not all of Mac softwares don't use BMP.

In Windows however, not so. BMP is the native image format in that OS. i.e.
used by the graphic kernel.

And you misunderstood our response. _Of course_ cropping discards
information - but it was information you didn't want! But also, when you
re-save a JPG image after doing anything to it, the lossy compression is
usually re-applied, meaning the information in the _remaining_ part of
the image is further degraded. Some of us were just pointing out that
there is available "lossless JPEG cropping". which achieves a crop
_without_ further degradation of the kept part of the image.

The information in the graphics RAM while a picture is on screen -
whatever the OS - is going to be raw image data, regardless of how it
was saved to or loaded from disc. (What _is_ the "native" format for
Macs then?)

it; I think it was in .pcx format (which was what the old scanner I'd
used produced). So formats _do_ fall out of fashion.

LCD.

then there's no radiation.

be sure it's using dvi/hdmi/displayport for the best quality.

if it's vga, it will not be as sharp.

Like TVs, they have threaded holes on the
back to accomodate mounting hardware.

some do, but not all.

false.

For you who uses Mac OS, that would be true - including *nix OSes. But not
for Windows and IBM OS/2.

it's false regardless of operating system.

there
is also the issue that a given raw format might not be readable at some
point in the future, whereas jpeg always will be.

some formats are proprietary and there is no guarantee that they will
be readable in the future. when the apps that can read/write them cease
to work, you're ****ed.

undo/redo can only be done *if* the crop is non-destructive.

with a destructive crop, there is no undo. those pixels are *gone*.
forever.

macs can read bmp, but given that the format is obsolete, it's
exceptionally rare that anyone would need to do that, on any platform
(even windows).

In Windows however, not so. BMP is the native image format in that OS. i.e.
used by the graphic kernel.

bmp is a file format.

He doesn't grasp the concept. It's like saying
we won't have words in the future, but that
English will always exist. The truth is the other
way around, but he doesn't grasp file formats.

I was reading an article
yesterday postulating that programming has become
a very steep learning curve simply because the
usage of a computer is so abstracted. Someone
can be a successful photographer working with
digital images yet with no need to understand
what a file is, how the image is stored, or even
where their images are. Fire up Adobe rental-
ware, log into your online storage, sync your
phone, edit images from yesterday's wedding,
then send them to friends.... There's no need to
have even the barest concept of how that all
happened or "where" the photos are, much less
what they are.
And there are lots of valorizing terms to make
it sound technical: "I'm managing assets in my
workflow" sounds far more official than, "****,
where'd I put that file?"

Your editing software is the important factor. There are several photo
editing application which can perform non-destructive crops which are
reversible, among them Photoshop CC, Lightroom Classic CC, On1 Photo RAW
2018, Luminar 2018, AlienSkin Exposure X3, & Affinity Photo.

As a Mac user BMP is far removed from my thoughts, and workflow. I shoot
RAW+JPEG, and use a RAW workflow, and usually the only time I use JPEG is
when I produce one for online sharing. Though recently I have been using
SOOC JPEG from my Fujifilm cameras, and their great film simulations.

In Windows however, not so. BMP is the native image format in that OS. i.e.
used by the graphic kernel.


Not being a Windows user, I don’t understand this idea of holding on to the
BMP format when there are much better ways to go.
