Help Me Humpa

Hey Humpa,

do you know a way of getting details about a jpg? For instance, I remember seeing somewhere when I posted an image, it told me everything about it - when it was created, the camera it was taken with etc. Is there a way in php to upload an image and it will tell you all this?

Cheers!

Not sure what is out there to get the exif data. You should find plenty of info on google though.
I looked into it briefly, but I recall the Motorola phones gave very little exif data, and half of it was wrong anyway.

Cheers - I guess I needed the key word - "exif" to search on as I didn't know what it was called. I've managed to knock together a simple little script that displays the exif data from digital cameras but not phone images - as you say, they don't seem to display a lot of stuff.

Cheers for the info icon30

The other thing I recall (and my quick search on google after my last post brought it back to the forefront of my memory) is that the exif standard is rather loose (or maybe just loosly followed).
Even some high end digital camera's don't show the correct (or perhaps complete) exif data except with their own software - or from software that is customizable (has special config files that need updating as new camera's appear or as someone writes a config file to handle certain camera's).

I agree - the standard does appear to be rather loose...To be honest, it was just something I got thinking about and wondered what could be done with it...So again, thanks for the info. I'll tell you what got me thinking about it...We had a cracking storm on Wednesday night and I had my phone taking sequence mode photos. I was taking a sequence of 6, if no lightning then just deleting them and starting again. I'd been going for about an hour and I actually managed to get this shot:

And one of the lads at work started saying "Yeah, nice Photoshop work" - he wouldn't accept the fact I just got lucky. It was then I started wondering if there was any way I could prove it to him.

cool ... nice shot

I think you can copy exif data somehow too, though - or at least preserve it somehow.

I remember I had to do something specific to get the exif data on my D70 pics when I converted them to jpg (though I forget what that was) - my gallery script shows exif data (though not at the moment, I see - I must be missing something to have exif data working on my new gate.com hosting)

When you say your gallery script, you mean the same scripts that I run? Please post up and let me know any details if you get it running again on gate.com.

BTW, THANKS for just saying "cool ... nice shot" and not, "No way, you must have photoshopped that" etc., etc., etc. Laughing

No, I just meant the menalto gallery that I use for my "real" pics:
http://www.humpa.com/phpnuke/modules/gallery

If you click on a pic, one of the links will say "Photo Properties" - that pops up a window which shows the exif data. But it is not working - I imagine it requires something that isn't installed on gate.com. I haven't looked into it, because I hadn't noticed that until just now (it used to work before I switched host).

Gotcha. Some cool pics there and wow! 5782x1856?? They are HUGE!

I just had a quick look on Google and I didn't realise but EXIF support has to be enabled on your server...I guess it is on mine as the little script I tried for exif data works, but my hosts recently turned off phpinfo() so I can't check stuff anymore...Which sucks Mad

I can't even add pics anymore though - I get errors, and I can't seem to resolve them. Sad

I'd switch webhosts again, but I just don't feel like it ... lol

I particularily like the seagull, which you can see better if you click on the full sized pic:

Holy sh*t! They are awesome. Did you take those? They really are fantastic! Really, really impressed Very Happy

Have you ever heard or seen of the 2.5 Gigapixel photo? Have a look here: http://triton.tpd.tno.nl/gigazoom/Delft2.htm to view the pic...Single click anywhere on the image and then use the + & - buttons to zoom in or out. And if you're interested, have a read here: http://news.bbc.co.uk/1/hi/technology/4022149.stm

I've seen that before ... but not in a while. That's pretty freakin cool though.

But any of my pics that are bigger than 3000x2008 are stiched together. That's the max size of my Nikon D70
There are some really cool panoramic sites too - there is one in particular that I really like, but I don't have the link to it. The guy has a panormic pic that is hundreds of pics stiched together - really amazing.

Every pic on my site was taken by me. Except maybe one or two (there are a couple of me, which I didn't take).
And all the pics in that menalto gallery (the humpa.com/phpnuke/modules/gallery) were taken with my D70 (except the Vegas gallery - that was my old Canon Elph)

I think this is pretty neat too - I wrote some little slideshow code to show some ski jumping shots that I took:
http://www.humpa.com/attitash/
Every one of the thumbnails is a slideshow that I took in rapid fire mode - they may be a little choppy, but that's just because I can only snap off 3 or 4 pics, and then it is just 1 pic a second after that (because I always shoot in RAW).
Though with only a 1024x768 monitor, those slideshows don't really fit on the screen very well. Sad

Unfortunately it's the end of my shift in an hour but I've got a lot to look at tonight Smile

You should be (rightly) very proud of a lot of the images you have taken...I LOVE the one of the USS Kennedy - that is fantastic.

I think maybe the other guy you mention is Max Lyons? He's done some great stuff with stitching hi-res images - I found some stuff here: www.tawbaware.com/maxlyons/gigapixel.htm

Really interested in the D70! How do you stitch the pics together?

...and all this because of a thunderstorm Smile
