How does JPG stop multiple reproductions of an image?


It doesn't.

The whole point of JPEG was to create a lossy format, to stop multiple reproductions of an image. It was not intended for editing or storage. It's doing exactly what it was designed to do.


JPEG was initially designed to transfer video and still images over slow ISDN lines, not to stop multiple reproductions. Storage was also a huge consideration. Perhaps it wasn't ideal for editing, but as the storage issue dissipated, JPEG editing became more common. With the resolutions of today, there is absolutely no reason why we shouldn't or can't edit JPEGs.

No, but some serious consideration should be given by the camera manufacturer's to the Jpeg2000 and other super Jpeg iterations.

It's time to move from an 8 bit Jpeg to one of the more advanced Jpegs moving up to 12bit image bit depth.

It's been played with, but the camera manufacturers would have to understand how much more marketable their camera's would be with a better color palette and other advances offered by 12 bit processing.

Any consideration of dumping current Jpeg is premature, since one must actually process about 10 to 12 "save" commands to view degradation without pixel peeking, or better said, "with the naked eye".

It takes about a dozen runs successively over the same file, for the compression algorythm to show up, as said, to the naked eye.

10 to 12?? Try like 30! But I get your point. You are being very conservative. JPEG hasn't lost any ground because the vast majority of image shooters don't care about full color gamut, artifacts or compression. It's all about portability and instant gratification; we don't even listen to uncompressed music anymore. Leave the ultra hi-res super duper color spectrum prints for the few professionals out there who actually know what they are doing. Camera mfg's aren't stupid. They do research---well, the better ones do. If they thought they could make MORE money removing support for JPEG, they'd do it in a heartbeat.

I am considering adding Nik Software to my workflow. When searching for products I discovered they were acquired by Google. The bundle package price seems reasonable; however, in my searches for information I come across some indications that since being acquired by Google there have been problems with support and assistance on Nik products. There seems to have been a drop of in promotion of the product. I even noticed their facebook page doesn't look like it has had activity for some time and there were negative comments about service. Is Nik software a good investment? Does anyone have concerns about support with future versions of Photoshop or Lightroom or operating software upgrades? Are they still working to enhance the product?

Nik is reasonably priced, and a solid suite. Get it and don't look back. If you want support, Google Youtube. Every question I have ever had about this software can be answered by a quick Internet search. There are also a few good books as a reference too. Silver Efex Pro 2 alone is worth the money!

Given that jpeg compression introduces artifacts and loss of definition wouldn't it be better to use a lossless format such as png and maintain an accurate image.

As the raw files produced by our camera's are accurate as we can get is converting to jpeg a reduction in image quality and we would get a better image from png or tif files. Historically space was at a premium but these days why not save in the most accurate file we can use?


No, but here's an interesting side note. Many professional photographers use Facebook, Twitter and/or Instagram to capture/reach out to a bigger audience. Like it or not, social media is a great marketing tool, and JPEG is the perfect format for this. Regardless, if you uploaded a full-res image to Facebook (i.e. a JPEG with 100% quality or no additional compression), FB further compresses your file by more than 80% (in some cases more than 90%). That's a lot of info just being tossed out (a SECOND time). Yet, some of the images I see are still stunning. Of course, printing is another story. Yet, your images have to capture someone's attention before printing is even considered. Unless, of course, you ONLY display your work in a gallery.

My point is that JPEG is far from dead, and many good professional photographers are very glad it exists, and you should too.

BTW: uploading a lossless PNG to Facebook did not fair any better, quality-wise, than it's lossy counterpart. In fact, many are convinced (myself included) that JPEG images look better than PNGs on social media, and in terms of Instagram MUCH better.

John, I completely agree.
My point is..., at what point are we going to stop comparing cell phones to REAL cameras!!! :lol:
SS


I think why many folks make the comparison is because we often judge a photo on many different criteria. You can take an award winning photo with an iPhone; likewise, you can take a crappy photo with an $8K DSLR. Just because a photo is technically perfect doesn't make it a good photo. A cellphone IS a real camera. The question is... is the person using the cellphone a real photographer? :-)

The reason cell phones are taking over is because they are user friendly, don't have a 500 page manual and most people are capturing memories, not pixel peeping.

Its the way of the future.


LOL. User friendly? I just got a Galaxy S5, and I have to say that it took me longer to learn it than my DSLR---had to ask my kids a lot of questions. Not sure what you mean by "taking over"... If you mean everyone has one, then sure they have taken over, but I'd like a hear how many pros with a DSLR are willing to give-up (not add to) their expensive gear for an iPhone to do a wedding?

Having said that, my S5 takes wonderful photos and captures great memories as you say, but it has a long way to go before it actually "replaces", for example, a Nikon D4S.

I do youth sports picture day, where I set up backdrops and flooring for the posing. I have strobes as well. Yet parents insist on whipping out their iphones and standing behind me taking shots. I am not sure if all of the parents are just using the set up to not buy pictures , but I feel I can not do anything about it. I have assistants that block shots inadvertently, their job is to get the shot not run interference. I know that not all parents can afford to buy pictures and are quite satisfied with a snap shot or two. My job is for the rest of the parents, to give them the best shot possible. There is very little time after the shot for parents to take their shot, since the youngsters move out of the backdrop right after we get our shot. Usually our crew blocks most of the shots. We however do not allow their flashes to go off when we are taking shots. It is just a split second or two that parents might get to take shot. It is not a big deal. We have to be professional at all times, and avoid any conflicts with parents. I do have one technique where I tell the parents standing behind me to move to the side as their presents are affecting the child. It works most of the time. I do not allow parents to use our set to pose their child between team shoots. I usually let them know that it would tie up the flow and we don't want to run behind schedule.

Can't you just ask parents (politely, of course) to NOT take snap-shots during the shoot? I'm not sure why you have to play any level of interference? Just curious.

Yesterday I went to a Cancer Fund raising event, in which my daughter was competing.
I got to the event in ample time to find a good spot to stand at the end which had some good views of a "Mud Chute"
About 20 minutes later this official photographer arrived and stationed himself and his equipment exactly in front of me ruining my point of view.
I asked him to move to one side but he just looked at me and completely ignored my request, I also couldn't move as the event was now very crowded.
I have experienced this before and cannot believe how very rude and inconsiderate this clan of so called professional people can be to their fellow photographers.
It was so bad that this photographer!! appeared in almost every shot I took.
I gave up so didn't get a photo of my daughter thanks to him.

It looks like there is some room in front of this guy! ha ha... Perhaps you just need a wider lens? Or, on the flip side, perhaps a longer lens would be more appropriate? Fill the frame, right? Might even get a more interesting shot? I love those up-close, mud-in-your face shots!

I think a little common courtesy by both parties goes a long way. Another approach, which I have used before, is to introduce yourself and ask permission to get a least one shot of your daughter. Whether you need to ask or not, it might just diffuse the entire situation?

8 pages on this? Really? :-)

Hi! I very much like the angle from which you took the bridge. We can see the architecture of its beautiful shape.

Would you consider cutting some of the bushes so that the bridge seems closer to the viewer? The bridge is the subject of the photo and I think so much bush is too much.

I also don't like the starbursts of the lights. They just don't seem real, even if they are. There's one on the right side that's not part of the bridge structure, but where there are buildings, that I would consider diminishing.

I also wonder if the bridge would stand out more if the background were not as well lit or in focus as the bridge itself. It's as if everything is the subject in this photo, when I think the bridge is.

Despite what I've written, a stunning black and white photo.

When shooting something at night, and the colors are changing faster than your shutter speed, what color would the final image be? Is there a particular color that is more dominant than another? Or should it just come out mixed or white? Thanks. -M

Filter on the lens? That is very interesting. I've never seen a starburst quite so perfect from the usual aperture decisions and I'd never have thought f4 would achieve one, but then I don't have great equipment so it might just be something I can't do with what I have.


No filter. Perhaps someone will comment and explain. Thanks. -M

Beautiful image well presented with excellent processing. I like the extremes of tonality that you chose. Great use of the curves and lines to make a really well balanced composition. You included just enough of the trees to get the context right without detracting from the main subject.

Not a fan of the starburst though. It looks too perfect, like it came from software rather than camera settings.


Thanks for the comments Minniev. This starburst actually came from the camera, and frankly, I'm a little curious why. My aperture was set at f/4. Generally, I have to set my aperture to f/11 or greater to get this affect. Possibly has to do with a short focal length, but not sure. The lens I used was a Canon 24-70L II.
