Dreaming To Be A Famous Photographer

can anyone help me understand what's the differnce between a jpe, jpg, raw, format? whats the best format used to use in capturing images? and why.

thanks in advance

 

JPG is the 3-letter file extension for JPREG images. Not sure what JPE is, but I would guess it's also JPEG> RAW is the image as it comes directly off the sensor. No manipulation, no compression, not even extracting the RGB out of the Bayer pattern.

 

I prefer RAW. Why? Because to me it's like having a negtive. IN fact, Adobe has a RAW to DNG (digital negative format) converter that preserves all the original image data. Converting to JPEG in the camera is, for me, a REALLY, REALLY bad ting to do. You let the camera make the first level exposure compensation decision for you. THEN you compress the file with a lossy compression scheme.

 

Simple truth about digital data (or ANY data for that matter) - once it's lost, it's lost, and no amount of clever extrapolation schemes will ever truly reconstruct the lost data. Once you go from an uncompressed format to a compressed format, you stand a really good chance of losing vital data. Every time you open then save an image in JPEG, you stand the chance of losing more and more data. Why should I do that to myself?

 

Why should I not try to preserve EVERYTHING that I captured, then make MY OWN decisions on how to extract the image information in the manner that best represents what I want the image to be? Why should I let some unknown engineer who may or may not be a photo junkie like me make my exposure, compensation, image extraction, and data extraction decisions for me?

thanks sir agxo3.. ive learned a lot... i really appreciate it...

i already got 2 lenses for my dslr camera.(18-55mm and 55-200mm) . im planning to buy one.. yung

wide angle lense.which of the list would you recommend? or if there are anything not on the list that

you may recommend, much better..what are the letters represents?

e.g. AF - S, DX, IF-ED, f, G? and the difference between a wide angle zoom lense and a wide angle lense

only. thanks again..

Hmmmm - good question! I'm not really up on what all those marking mean for Nikon lenses. The "f", though, is a standard marking that refers to the maximum aperture of the lens.

 

The aperture number given is the ratio of the diameter of the aperture to the focal length of the lens. That is, if the focal length of the lens is 28mm, then the maximum aperture of an f/2.8 lens is 10mm. A lerger aperture means more light enters the camera, so a lens with a large maximum aperture (a small "f" number in the lens spec) will allow a faster shutter speed in low light situations.

 

Zoom vs. prime - a prime is only one focal length, a zoom allows you to vary the focal length.

 

"ED" refers to the dispersion characteristics of the glass. "DX" typically menas it's a lens designed for a digital camera application as opposed to a conventional lens. "AF" means autofocus. "S"??? Who knows? Check the Nikon spec sheets. "IF" typically means "internally focusing" which is one lens focusing method for zoom lenses. Which focal length? Depends on what you want to shoot. I like larger apertures instead of smaller apertures, becasue of the flexibility they give me - I prefer available lighting (ambient lighting) over flash for most of what I do.

 

I personally prefer prime lenses instead of zooms whenever possible. I find primes to be better quality lenses, and cheaper, too!That does not mean that I do not own zooms - I do - but that if I had to choose a lens for a specific application, instead of a general purpose lens, I would choose a prime.

 

All of this is pretty basic stuff, and if you're asking these kinds of questions, then it's clear that, while you are trying to learn (and that's good!) you have a long way to go. I will make the same suggestion to you that I make to all who wish to take up photography - go learn the basics. Pick up a book. Attend classes. Practice. Learn.

Just to add... JPEG stands for (Joint Photographic Experts Group)

I shoot RAW as well... aside from the fact that RAW gives you more flexibility in your images... it also discourages me to shoot just about anything because it eats a lot of memory space... this instills discipline to carefully choose my shots...

Like what the master said... its like a digital negative in your cam... I have several images that has been saved because I shot in RAW... sure it would take more time in processing your photos... but believe me... its well worth it :)

I would actually recommend getting 12-24mm f4 for a wide-angle... but I suggest you get the Tokina equivalent instead of the Nikon one... primarily because the Tokina is HALF the price compared to Nikon... you could spend the money you 'saved' for getting other gear...

 

Happy shooting :thumbsupsmiley:

"Zoom vs. prime - a prime is only one focal length, a zoom allows you to vary the focal length."

 

correct me if im wrong, so when you're using prime lenses, you'll not be able to "zoom in" or "zoom out" your subject?

what's the spec of the lense you recommend for me to buy (for wide angle lense)? yung tipong ang vertical or hirzontal lines

dont appear to be straight lines.. yung nagcucurve na sila..thanks

The only difference between zooms & primes are 'manual & auto' zooms... with primes you have to zoom in or out manually... meaning you'll have to walk towards or away from your subject... hehehehe :P

 

The one I recommended (12-24mm / f4 - Tokina) is a great UWA lens. Very minimal distortion compared to its UWA counterparts for half the price of its Nikon equivalent :thumbsupsmiley:

can an slr lens be used for a dslr?

 

it depends on the SLR lens and the particular DSLR...it would help if you could be more specific.

 

For Canon cameras, as long as the lens is an EF mount (canon lenses that have auto-focus), yes they can be used on ANY Canon DSLR

 

For Nikon, not all auto-focus lenses can be used, especially if you're planning to use it on a D40 or D40x

 

For Minolta auto focus lenses, you can still use them on the Sony Alpha cameras, or the older (and defunct) Konica-Minolta Maxxum DSLRs.

 

For Olympus and Panasonic, I would have to say that you're out of luck. those cameras use an entirely new line of lenses (4/3s or four-thirds mount)

 

I'm not sure about Pentax cameras though... never had a Pentax SLR... don't know anyone who has...
