Default Whats a good image management app?

What's a good program that can do operations including compression on multiple images? I just noticed my new camera folder album exceeded 2GB, which is ridiculous. I've noticed the given resolution of taking a picture with every digital camera is always twice the real resolution less. It's so obviously blurry it looks upscaled. Same thing with 1080p Blu-rays, they all look upscaled 720p. Pure waste of bandwidth and storage.

So is there a program that can resize all my images to 50% and then apply compression, preferably the compression being customizable. I always go with 95 for photos I need perfect and 80 for the rest.

There are tons. I suggest Irfanview. Photoshop also works well, but
not many people have it. Photoshop Elements is a very good program
that doesn't get mentioned very often.

I haven't seen a digital camera where the resolution (and inversely
the file size) hasn't been adjustable. Sounds like you may need to
visit the camera's menu system and play with the options.

It's so obviously blurry it looks upscaled.


Make sure you're not using digital zoom. Other than that, make sure
the lens is clean. Digital cameras made in the last 5-10 years should
have no problem creating very clear images.

Same thing with 1080p Blu-rays, they all look upscaled 720p. Pure waste of bandwidth and storage.


You have something wrong with your display device, your playback
device, or your source material. You didn't provide enough information
to be able to narrow it down any further.

Yep, see above. There are many.

I have Photoshop CS6 tho I'm a newb to PS, I got it recently. Its quality selector is non-standard, its from 1-12 while the standard is 1-100.

You totally missed the point. Yes, the resolution is adjustable and I naturally select the maximum the camera allows, but it ends up looking so obviously blurry and upscaled that it may as well not exist, and the makers of these **** cams oughta be sued for false advertising. Why did I pay $90 for this hunk of junk when its only capable of half the megapixels it advertises?

The file size is adjustable too, the problem is the camera's compression algorithm sucks ass and it requires nearly the same filesize no matter the content. Lots of my pics are indoors with a solid white wall and its maybe 100-200 KB smaller than the more complex photos.

>It's so obviously blurry it looks upscaled.

I've made sure of both. The max selected resolution is still fake.

No sir, it is quite common for idiot entrepreneurs to exaggerate and push the limits of technologies to give as low possible quality at the highest possible resolution. A blu-ray resized to 720x576 looks way better than a DVD of the same resolution. In fact, I've found most DVDs real level of detail to be around 360p, not 480-576p.

Nothing's wrong with any of my equipment, what's wrong is that ****heads are trying to sell the public garbage and get rich. A rather common practice in America.

Here's a screenshot straight from the Blu-ray, does this look 1080p to you?
http://i45.tinypic.com/2dsgvwi.jpg

The level of detail in that particular scene is not even 720p! Obviously upscaled.

If you say your unspecified digital camera is a steaming pile of crap,
I won't argue. All I can offer is to do more homework next time. Check
specs, check user reviews, and take advantage of return policies if it
doesn't work as advertised. My digital cameras don't produce blurry
photos in general, although they tend to struggle a bit in extremely
low light conditions. I'm aware of that, though, and it isn't a
problem for me.

With zero knowledge of the source or any of the equipment involved in
playback, I can't begin to hazard a guess.

This has happened on 3 cameras I bought in a row.

The equipment you speak of is a built-in blu-ray drive in my computer and decoded by FFDShow. But I really don't see the relevance. This is digital. It either works or doesn't. The only artifacts that do exist from improper decoding are corrupted frames, wild colors you normally need to drop acid to see or slight brightness/contrast offsets. Blurriness is never a digital media artifact.

Btw, I welcome you to give me any screenshot straight from a Blu-ray with true 1080p detail. That would be a sight to see.

The term "1080p" doesn't infer any specific level of detail or picture
quality. It can be the blurriest picture you've ever seen and still be
displayed at 1080p.

Well, now you're mixing topics.

Video is a different animal than still camera shots. Video does
both spatial and temporal compression (for video formats that
involve compression). If you shoot video of a perfectly still scene,
then the I-frame collected should be reasonably equivalent to a
still camera picture. If there is motion in a picture, any
particular frame selected from the video, may not look
very good as a "still".

http://en.wikipedia.org/wiki/Video_c..._picture_types

As for your camera, and the lies they wrote on the side of the
box. I'll give an example. My webcam is 1280x1024 native format.
Yet, it promises to shoot 5 megapixel pictures for stills. When
in fact, I know I've got all the detail it has to offer, if
I shoot in the max "native" resolution. That's what you want
to do with your camera, is use the native value. Not any value
which requires interpolation to make any in-between pixels to
pad out the image.

Some cheap cameras, only record in compressed formats such as JPEG.
They do this, because the built-in flash chip is so small, and they
want to be able to claim the ability to store a large number of
photos. Whereas the users, would want the image to be recorded
at native resolution, in an uncompressed format (BMP or some particular
TIFF format). Some camera users will select RAW as a format, but
this has implications for aspects other than just the number of
pixels.

As for compression methods, there are "lossy" and "lossless" methods.
If you have an 8 bit photo, you can use GIF as a "lossless" compression
format. No information should be lost with a lossless compressor, but
the level of compression to expect is relatively low (maybe 3:1 to
just make up a value). Things like JPEG, on the other hand, have a
"quality" factor, which goes hand in hand with compression ratio.
I could probably get a 100:1 compression ratio with JPEG, but the
resulting image would only be fit for the Trash Can.

http://en.wikipedia.org/wiki/Jpeg

"Sample photographs" [ three quarters of the way down the web page ]

Some cameras, will "soften" the image before storage, and this may be
an attempt at noise reduction. You can "sharpen" the image with
Photoshop or equivalent, to get back some of the detail. Oversharpening,
is a form of digital mutilation, so don't "turn the knob too far".
After a few trials, you'll get some idea what looks natural, and
what looks like "too much".

If shooting stills, with a camera with excessively noisy sensor, and
the scene is *perfectly still*, you can shoot two photos, one after the
other, with exactly the same lighting, then use Photoshop arithmetic
operation to compute (A+B)/2 or the "average" of the two images. This
helps reduce the noise to some extent, but without degrading the image.
But it only works for things like indoor scenes, where everything
in the scene is under your control. I used that technique, when
preparing photos for a "how-to" manual for something constructed
indoors. Every shot, consisted of two pictures, with the pictures
averaged together to get rid of camera sensor noise. It's what you
get, from a $100 camera. Even with halogen lighting of the scene,
there's still sensor noise present. Better quality sensors, make
that less evident (until it gets a lot darker).

HTH,
Paul

But is that really so bad? I think it greatly depends on the compression
used. Who wants to deal with such a huge file as BMP in the first place?
Or raw video, for that matter (instead of compact MP4 video!).

I only hope if/when I get one, it will have JPEG and MP4 output capability,
not BMP and/or raw video.

They do this, because the built-in flash chip is so small, and they
want to be able to claim the ability to store a large number of

That's a pretty good reason though, I think!

I guess this is assuming most users want the best possible image/video,
regardless of the file size. I sure wouldn't. (for the same reason I
prefer to have a collection of MP3 files, not WAV files, stored on my
computer)

Interesting link. I think even the 23:1 compression one looks pretty good!

My experience with JPG compression is you can often compress the image quite
a bit, and still get good results - and save a ton of disk space. But it
depends on the image.

It all depends on what you want to do with the photo. If you're just
going to print the photo on your inkjet, or send to Walgreens or
similar, the JPG will be just fine.

But, if you're a professional photographer, the Ansel Adams level, a
compressed format is the last thing you want.

It's somewhat analogous to the music you hear from a record or tape
(JPG) or a CD/DVD (TIFF, RAW, BMP).

Absolutely. You shoot and keep/archive RAW format but you deliver in JPG.

Or especially if you're going to blow up that print too, I guess, which I
guess is what a professional photographer might also need. That, in
addition to not seeing ANY artifacts, I guess, no matter what s/he does with
the image.

It seems it might be better to either sell two types of cameras, then, to
the two different markets (pro vs amateur), OR at least offer the option to
save in JPG and MP4 formats, which, I would think, would satisfy the vast
majority of most customers. (I mean, the savings in disk space is so
huge).

I guess I can relate to this somewhat, in that whenever I work on or restore
an audio file (as a hobby), I really prefer to work directly on the WAV file
format, and not the compressed one it may have come to me in. And
actually, if it's not in WAV format, more than likely I'll convert it to
WAV, and leave it there, until all my restoration work has been applied to
it, and I'm satisfied with the results.

But I probably won't retain it in (uncompressed) WAV format, because I'd
fast run out of disk space if I did so. I suppose if I were working in a
sound studio, as a sound professional, with unlimited resources, I'd leave
it that way, however.

Oh. Ok, good to know.
Hopefully the P&S ones can save in JPEG for stills, and MP4 for videos,
although I'm guessing that the latter (video) may still be using the old AVI
format (which is a pretty old format nowadays), in most instances. I
haven't checked into it, because I'm not really in the market, but it's just
interesting to be aware of these things. :-)

Btw, I welcome you to give me any screenshot straight from a Blu-ray

The term "1080p" doesn't infer any specific level of detail or picture
quality. It can be the blurriest picture you've ever seen and still be
displayed at 1080p.

I think we all know what IOne means, however.

(Equally, the p does not convey anything about the detail that could be
extracted as a still.)

As for compression methods, there are "lossy" and "lossless" methods.
If you have an 8 bit photo, you can use GIF as a "lossless" compression
format. No information should be lost with a lossless compressor, but
the level of compression to expect is relatively low (maybe 3:1 to
just make up a value). Things like JPEG, on the other hand, have a

Though "8 bit" is not actually wrong, in that GIF can use 8 (or, I
think, 4 or 1) bits per pixel, I don't _think_ the colours have to be
8 bit colours: GIF selects a palette of 256 (or 16 or 2) colours, and
records which one each pixel in the image is - but I think the colours
can be 24 bit. For example, a picture of a sunset might have 256 shades
of yellow orange and red), but each one can be store to finer detail.
