I saw some cool birds today and completely failed at taking cool pics of them with my K-50 and 50mm lens, so I'm thinking about ordering a telephoto one.

I'm trying to get a feel for the difference it would make if i went from 50 to 300mm and I wanted to sanity check my math because i have no idea how camera math works and this is the first time I've done trig this year probably.

According to this site the horizontal viewing angle would change from 39.6° to 6.87°, so the change in the focal plane is sin(6.87/2)/sin(39.6/2) = approximately 17.7%

So if I shrink a pic from my camera now to 17.7% and then paste the (now severely cropped) original into the smaller resolution version, this is a decent comparison for the relative size of things in the frame, right?

Obviously the resolution won't be representative but I'm just trying to see if 300mm is like omg way too close up or not.

For bird nerds 300mm is like the starter focal length. :v:

They habitually go for 600mm and often use a teleconverter too.

with a 300mm you're zooming in 6x compared to a 50mm.

Unfortunately this is pretty true. Think about your budget, how heavy you are willing to go, and whether you want something that's multi-purpose or really a dedicated critter lens. The basic 70-300 that most manufacturers have is where many people start but most wild birds are small and shy enough that it's not ideal.

Bird photography is a very slippery slope, you're always lusting after more reach. 300mm is a good start. Do that. But be ready to start looking up eBay auctions on 50-year-old screw-mount super teles because your Pentax can happily wear them and you can achieve the lofty heights of 500mm and F/4.5 for only a dollar per millimetre!

While technically correct that is a poor way of conveying how much larger something actually gets in the frame when you change focal lengths.
Going from 50mm to 300mm is a THIRTY SIX (300^2/50^2) times increase in the size of the subject (or the area it fills in the frame)


300mm is a quite short focal length for birding, unless you are either at the zoo or in some organized event where large birds (eagles or bigger) swoop in really close to grab bait.
Even 600 is short if you want to photograph smaller birds

I managed to grab it for £89.99 a few months back for 12 months. So it does happen from time to time but I don't think there's much rhyme or reason.

I family friend left a few old cameras and gear with my parents about 6 years ago and they're tired of holding onto it so they gave it all to me... From what I've found most of it isn't worth much -- there's two Minolta SRT101's, a Revere Stereo 33, an old Kodak Instamatic Reflex, along with a few others. But there's also a Mamiya C330 Professional that eBay tells me is worth ~$250-550. I'd like to sell it but I don't know anything about this style of camera... how do I tell if it even works?

This is great so far. From one of the optional readings:

quote:

We simply have to mention sepia toning. It is probably the worst thing that has ever happened to photographs but, like neckties and hair dye, it’s out there and has long been around to make things look silly. Somehow the idea grew in the first half of the century that a photograph could somehow be better if it was brown.

Wikipedia agrees with you:

quote:

Sepia toning is a specialized treatment to give a black-and-white photographic print a warmer tone and to enhance its archival qualities. The metallic silver in the print is converted to a sulfide compound, which is much more resistant to the effects of environmental pollutants such as atmospheric sulfur compounds. Silver sulfide is at least 50% more stable than silver.

I got some prints from Parabo recently when they were running a special on twenty 4x4" prints for the cost of shipping. They're pretty decent and I plan to use them again for bigger stuff. They're running a similar special for even tinier prints right now I think.

I have good results from bay photo for prints. They hosed up my Christmas cards two years in a row though (prints were skewed on the card stock) so I'm going to try national photo lab this year for cards.

Instead of doing a traditional photobook through some photo service, I used blurb to design and print a trade book. It gave a lot more customizability to how things were laid out, and I liked being able to get it printed on matte paper. I can't speak too much for the quality, because I chose to try the worst quality printing they offered, which I think probably correlated to some sloppy work putting the book together.

On the other hand for the worst quality printing I only paid $16 shipped for two copies, and I did like the look and feel of it a lot more than a glossy photobook.

Was this a just-for-fun book? I started trying to price out options for a small photo book project and it seemed like a possibility, but I was a little worried about what the low-end trade book options actually looked like. I guess I should just start by ordering on the lowest reasonable level and inch up in specs until it looks like something someone would actually pay for as a visually appealing item.

It was just a family photo album, I just wanted something like a more traditional book. The lowest end color print quality was pretty bad, lots of vertical streaking, and some pages were cut badly enough you could see coding marks that are way off the page. I think without that and the streaking I would have liked the low-fi look of it, and the paper and cover were nicer than other people's small run books I've bought. I was tempted to try another, but at the time at least you could only make that choice when making the book, so I would have had to resubmit it if I wanted to try the better quality printing.

Actually for the price it wasn't nearly as bad as stuff I bought from major publishers for similar prices at reading fairs as a kid.

Ok looks like we are getting the X-T3 to do baby and sailing photography

It looks like a couple people sell an aluminum thumb rest for the camera family that plugs into the hot shoe, is this worth looking at getting

Anything else I should look at getting? If I have a tripod somewhere, it's a piece of poo poo $19.95 model from walmart and it's at the bottom of my storage unit

X-T3 is a loving great camera, thanks to whoever suggested it

The battery charger is still plugged into a socket in the kitchen from the day we got it, being able to just leave the camera plugged into the USB-C phone charger at my desk is fantastic. The battery is always topped off, ready to go. I bought two extra batteries but I've never even tried them, being able to charge the camera with a regular charging cable is loving great, really glad we didn't compromise on the USB-C charging requirement

Picked up a $12 manual Canon FD (1970-1985 lenses) adapter, was able to plug in my dad's old (and free) FD 50mm 1.8 and 35-105 3.8 lenses with no problems; picked up an 80-200 2.8 and a 100-300 5.6 for $70 shipped, so I think I'm good on lenses for a while. I ordered a $15 FD 2x teleconverter off ebay for grins, and oh, I have a $99 7.5mm 2.8 lens on order. Really enjoying that you can plug cheap vintage lenses on this thing.

Thanks for the feedback on Blurb. It's definitely what I'm going to check out first. I mainly need something with good bright colors that I can do at a fairly low price point. The photos are all natural light iPhone photos like this one (I'm going to crop/edit to make it punchier but you get the idea).

Yeah we've done a family photo book with them every year for the last 10 years. I always do their highest quality paper and print options and have been very happy with the quality. A hardback photo print 8x10 book with like 150 pages ends up costing around $150, but they always run a half-price special for black friday. So we make it our thing to finish up the book layout around this time and be ready for the sale. Every since our daughter was born I buy a copy for myself and one for my parents as their gift from us, and they love it.

I'll also mention that if you use lightroom classic (aka the only real lightroom) it's very convenient that it has a book module that lets you lay out the book directly from your library, and then export a PDF for digital archiving, and upload directly from lightroom to blurb. The book module in lightroom is slow, like the rest of lightroom, but you can't beat the convenience of laying out directly from your main library.

you mean you cant readily quote the names of five tomes for grinding your own lenses and building your own auto light metering devices?

but seriously, i would go as far as suggesting the OP look up a few videos on youtube to learn about the relationship between shutter speed, iso, and aperture. those concepts really are best explained "in person" and the medium of video makes it easier to illustrate the impact of each.
i can't say i have read a photography book to learn about technical stuff, but those that i do have are more about inspiration for the kind of things i would like to work towards.

For basic exposure triangle stuff, the go-to is Understanding Exposure, by Bryan Peterson. For all these kinds of books get it with color prints, not as a black and white kindle. You need to see the example photos which illustrate the principles.

https://www.cambridgeincolour.com is a great website that explains many many photography concepts with good figures and interactive tools.

Bryan Peterson's Understanding Composition is good, too.

I read a few books on studio/off-cam flash lighting, as well as weird DIY lighting solutions and they all illustrate the interesting ways you could manipulate light for your work, as photography is lighting.

I just bought it but use On1 for raw file editing, with the idea to Affinity Photo for more… well Photoshopy touch ups and all that. By all accounts Capture One is still better for off the camera file conversion and that but no idea yet on how the photo manipulation and correction side stacks up.

It's a real decent deal though, I saved a bit.
