How much do megapixels matter?

Hello, i am stuck between the canon rebel t4i and the nikon d3200. The nikon has 24 megapixels, whilst the t4i has 18. I have a retina display macbook pro and i will be wanting to take pictures up to 2880x1800 in size. Can the t4i handle this? I like everything else about the t4i. I will be shooting pictures of nature and also taking video. Can you explain how many megapixels i need and what they do? Will i be able to take 2880x1800 pics with the t4i? With the d3200? all feedback is appreciated; thanks so much in advance :)

My Nikon D5000 delays in taking pictures?

I am an Ametuer photographer, and I have a Nikon D5000, I've had it for about 2 years now, and it seems that when I'm taking pictures it takes a long time for the camera to actually take. I'm getting frustrated with my camera because I've missed SO many great facial expressions and perfect moments because my camera wouldn't take the picture. I don't understand why.Is it a setting on my camera? Maybe, something to do with the lens? I've used friend's Cannon cameras before and they don't do this, I'm considering switching brands, but I've got so much money invested in Nikon, I don't want it to be a waste. Help! any suggestions?

Is this depth of field?

I used my aunts really nice lens yesterday, and loved the results I got. Example:

and…
http://www.flickr.com/photos/adripendletonphotography/8212156149/in/photostream

They were taken with a Canon(not sure what model) and a 70-200 lens. What I really love about these is the way the background is so blurred out.Is this what depth of field is?

My new lens(the Nikkor 18-200mm VR) should be here within a week, and I'm wondering if the lens I'm getting is capable of making the backgrounds of my pictures like the ones I linked to above.My old lens(the standard kit lens) never did this for me.

So, is this depth of field? And how do I get results like that with my new lens - if possible?

Please excuse my ignorance - I'm pretty new to photography, but I'm learning quickly :)

How macro is the nikon 40mm f/2.8 lens really?

Here is the lens I'm talking about:
http://www.amazon.com/Nikon-40mm-2-8G-Micro-NIKKOR/dp/B005C50H2Y
It supposively focuses at 6 inches, but I tested my 18-55 mm kit lens at 40 mm and it seems to focus around 6 in from the subject as well, but in no ways do I see it as a micro lens. How could this lens be macro if it focuses at the same focal length that my kit lens does?

I know it is probably irrelevant, but I have a nikon d3100.

How to get chrispy pictures in low light with Nikon J1?

Whenever i take pictures with my Nikon J1 in low light, they always end up kindof blurry.for and example, i was taking a picture of my sister and my cat by the fire, and i turned out blurry, even though there was afternoon light.

I love taking pictures in the evening and night (especially the night sky) so any help will be very appreciated, Thanks: D

The best budget AF (autofocus) film SLR? - 1

Hello! I'm looking for a film SLR that has an autofocus feature.

Preferably by Nikon or Canon and within a budget of USD $250, of course this would mean I'd buy it in secondhand condition.

Any suggestions?

Canon 60d and the nikon d7000?

Well i see that the Canon 60d has a burst rate of 5.3fps and the d7000 has 6fps. Now is that alot of difference? Im merging into sports photography and want either of these cameras.because the nikon has 0.7fps more than the canon, does that mean that then nikon is better for shooting sports photography (Football)(UK) or is there other things that will make a camera shoot nice crisp pictures when things are moving? that i don't know about and have to look out for.
Cheers

Was the 16-85mm a wise purchase in addition to the 18-105?

My parents recently bought the Nikon D7000 with the 18-105 kit lens online. (I know most say that it's a better idea to simply buy the body and skip the kit lens, which tends to have lesser quality, but the body and the entire set were both the same price.) This will be our first digital SLR, although we do have experience with film and point and shoots.
I tried to do some research online about which zoom lenses to buy in addition to the kit lens and on a Flickr forum many people said they used their 16-85 most often when leaving the house. We decided to order this lens as well but now I'm not so sure if it was necessary. The 18-105 has the same aperture range (f/3.5-5.6) and it offers a slightly larger zoom range. A comparison between the 16-85 and 18-200 on Ken Rockwell's website revealed there wasn't a whole lot of difference between the 16mm and 18mm wide angles. I realize the kit lens is made of a plastic mount, and the quality of its materials is cheaper, but is there a recognizable difference in quality in the photos produced by the 16-85 and 18-105?
It just seems to me that the 16-85 is simply a more convenient, condensed version of the 18-105 lens--am I mistaken?
Hmph this question ended up longer than I thought it would be but basically, I'm wondering if my parents' money was well-spent on the 16-85 or if it should be exchanged for another lens with a similarly versatile range but a larger aperture.

Shutterfly photo book quality?

I had a baby in April so for Christmas I wanted to make photo books for all my family members through Shutterfly. I just created a 12x12 book online and I'm a little worried. Before I go and purchase $150 worth of these, I want to get others' opinions. I have pictures on there from a variety of different things (droid x, droid razr maxx, sony dch-10, nikon d90, nikon d3100 and nikon d3500) I tried to get all the pictures from my phone to be smaller in the book so they wouldn't be too bad, but looking at the pictures from even the nikons they look a little blurry or pixelated when I preview it.Is this normal? I just dont want to pay $150 and have crappy looking pictures. I'm looking at all the pictures on my memory card and they look perfect.Is it just because of their website or something?

Is it worth it to invest in a lightroom program?

I'm interested in shooting in the RAW mode on my Nikon D50 now that I'm finally getting a good lens. Can you tell me… What are the advantages of shooting in RAW? In programs such as Adobe Lightroom(and any other programs for RAW pictures), what kind of editing is done in them? Is it worth it to invest in these, is there a noticable difference in quality of the images and how they turn out?
Anything you can tell me would be appreciated. Thank you!
